What is a Master Gardener? A Master Gardener is someone who has successfully completed Master Gardener classes offered by an extension office. Classes provide research-based information on core subjects ranging from botany to soils to plant pests. Trees, turf, and landscape plant growing principles are also covered. Master Gardener volunteers take the knowledge learned through these classes and put it to use in their communities – sharing knowledge informally with others, teaching, and doing various gardening-related work in public areas.

How do I become a Master Gardener? Complete classes offered at the extension office and complete 40 hours of volunteer service within one year of course completion. Volunteers complete 20 service hours annually in subsequent years to maintain active Master Gardener status.

Where can I volunteer? There are several ongoing volunteer opportunities at Yew Dell Gardens and Creasey Mahan Nature Preserve, plus one-time opportunities that are announced throughout the year. Participants may help with an existing project or begin their own. A project can be as simple as helping plant or maintain your church’s landscape or providing plant recommendations for a neighborhood association common area. The possibilities are endless.

Landscape Help Publications Available

The following Agriculture & Natural Resources and Horticulture articles printed in the Summer 2017 edition of the quarterly Oldham County Extension newsletter.

‘What is Your Tree Worth?’ Landscape trees can add to the value of your property if undamaged, healthy, and planted in an appropriate location. This publication describes how to have your trees evaluated to determine their value in your landscape.

Get Help With Pond Weeds

A common problem for pond owners is control of weedy plants. Correctly identifying the plant is the first step in managing it. Scoop up problem weeds in a bucket and bring to our office for identification and control tips. Keeping pond weeds in water helps preserve them for accurate identification. An open container is best because it keeps the sample fresher. A closed container can be used for same day delivery to our office, but plants will begin decaying if kept enclosed multiple days, especially in a hot environment.

KY Spring Native Flowers

Home to over twenty-five hundred plant species, Kentucky is a veritable wildflower garden. Kentucky native spring flowers include bloodroot, spring beauty, and Virginia bluebells.

KY native wildflower

Bloodroot

Spring Kentucky Native Flower

One of the earliest blooming wildflowers in Kentucky, bloodroot (Sanguinaria canadensis) appears in the late winter and early spring. This native wildflower gets its name from its red-orange rhizome and the red juice that can be squeezed from it. Native Americans used bloodroot to treat fever, ulcers, ringworm, and skin infections. It finds use in dye-making and is also being studied for possible anti-cancer properties. Bloodroot, however, is toxic when ingested, causing vomiting and loss of consciousness.

Bloodroot can be planted from seed or through root division. It can grow in sun or shade as long as rich, moist soil is available. You will find this short wildflower in both Kentucky’s woodlands and open fields. Bloodroot’s white flowers, yellow stamens at the center, are about an inch and a half to two inches across. A single round leaf accompanies each flower.

KY wildflowers in blooms

Spring Beauty

Kentucky Spring Wildflower

Spring beauty (Claytonia Virginica) is another of Kentucky’s early spring wildflowers. Less than a foot in height, the small white to pink flowers emerge before the trees begin to leaf out. Spring beauty opens in the morning to take in the sun’s warmth and closes again each evening. Its inconspicuous leaves blend in with surrounding grasses. Like many wildflowers, its loveliness is fading, blooms lasting only a couple weeks.

Claytonia readily reseeds itself and can be found soaking up the sun across the eastern United States. Gardeners can collect the seeds to bring a little spring beauty to their own gardens.

Spring beauty owes its name to John Clayton, an eighteenth century naturalist who so impressed Benjamin Franklin that the founding father “granted him free mail privileges for shipping his plants and letters.”

KY wildflowers in bloom

Virginia Bluebells

Ephemeral KY Native Wildflower

When traversing Kentucky’s woodlands in the early spring, you may encounter Virginia bluebells (Mertensia virginica), also called cowslip or mertensia. Virginia bluebells flourish in sandy and loamy soil and can often be found along creeks and other waterways. Nurseries and seed catalogs also carry these spring beauties. The nodding, bell-shaped wildflowers vary from blue to purple to pink. The inch-long trumpets bloom in clusters. Bluebells grow to a height of one to two feet, and if the growing conditions are right, they may quickly spread and naturalize. Bees, butterflies, and moths all pollinate them.

This Kentucky native wildflower springs up after the last hard frost in March or April. A spring ephemeral, Virginia bluebells only bloom for two to three weeks before going to seed. The foliage dies back by early summer. Mass plantings are breath-taking while Virginia bluebells are in bloom, but they are short-lived and may leave a “hole” in your landscape once they have died back. Keep this transience in mind when planting bluebells in your garden.

Virginia bluebells were a favorite of Thomas Jefferson’s and still grow at the Monticello today.

Adapting Your Garden As You Age

Tips For The Aging Gardener

Love gardening but afraid your body can no longer physically handle the work? A few simple adjustments can help make the work easier, allowing you to continue enjoying your hobby.

Like an athlete, the gardener develops gardening skills through repeated activities like digging, weeding, mulching, etc. We learn how to use tools to get the job done with the least amount of efforts and the best results.

gardening tips

Through my wife, an occupational therapist, I have learned a lot about adapting physical activities to fit a person’s ability. Her background includes work with children and seniors.

I have been gardening and landscaping since the late 1970s. Following my back surgery in 1995, I discovered the importance of proper lifting, carrying, and digging techniques for gardening. Recommended habits can be modified. Don’t wait for back surgery to take a look at your gardening habits. I still garden and do strenuous work, but I listen to my body and take a break, change my position, or stop when needed. Well, sometimes I go past my limit — but not far — and when I do, I pay more attention to my posture. Staying active is important to maintain endurance, flexibility, and energy.

The Aging Gardener

When we age, endurance is often the first thing to go. We can’t work as long. We feel weak, unable to lift and move plants like we used to, and familiar tasks take longer to complete. If you’re having these experiences, it might be necessary to reevaluate the size of the garden or change its maintenance requirements. Reduce the overall maintenance of deep perennial beds, for example, by making them narrowing and backing them with shrubs.

The loss of flexibility is also one of the first signs of aging. An injury or development of arthritis are among several things that can cause reduced flexibility. This limits our ability to maneuver in the garden: getting up and down, twisting or changing position while pulling weeds or picking flowers, and cleaning up dead leaves. Of course, gardening does help us maintain flexibility. Reduced flexibility needs to be considered when we decide what needs to be changed to make it easier to maneuver in the garden.

Additional limiting changes include poor balance and persistent back and joint pain. Once these changes start, gardening becomes more of a challenge, so modifying your garden as you develop it could help in the long run.

Adapting Your Garden As You Age

Let’s look at the garden. What is the size and layout of your garden? Is your garden large with numerous perennial plantings and border gardens, or is it smaller, including just the area surrounding your house with maybe a small vegetable garden? The style, size, and area of your garden will determine the approach needed when making modifications so that you can enjoy gardening again.

Note that annual and perennial plantings need a lot of maintenance because of their constant change and growth rate. Lawns, trees, and shrubs also require maintenance but not as often as flower beds.

We don’t want to limit our garden, build expensive raised beds, and, most of all, reduce the size of our garden once it is established because there are always new plants to try. We should look ahead. Look at what has recently changed in your ability to maintain your garden. What are your immediate limitations? Decide what you will be able to handle and still enjoy gardening. Will you be able to have someone available to help (maybe a family member or young gardening enthusiast) to keep your garden as it is?

gardening as you age

Gardens are a collective of plants that we desired to grow at one point or another. Some, though attractive, are not your favorite. Select those plants that are your favorites and reconsider how to handle the rest. Changes based on a landscape plan can be made all at once or over a period of years. If you decide to do the work yourself, start with your most labor-intensive space. Look for plants that need less attention. Reduce the overall maintenance of deep perennial beds by making them narrower then backing them with shrubs. Another solution might be creating a pollinator garden that requires minimum upkeep and can be mown off once a year.

Reduce reaching distance and amount of leaning forward to pull weeds or spread mulch. If you can only access a bed from one side, ensure it is no wider than two feet. Beds accessible from both sides can be four feet in width.

To make the work easier, use quality tools and keep them clean and sharp. A rusty shovel is more difficult to dig with because the soil will stick to it more. A sharp hoe will cut through weeds easier than a dull one. Consider automatic watering and semi-automatic watering systems for gardening to reduce the amount of hand watering. Soaker hoses and single drip emitters are two options.

Making Your Garden More Accessible

Once you have decided what changes to make to your garden, you can make them yourself with family help or hire a landscaper to install them for you.

The design of large gardens will need to provide easy access to all the plants with wide, level walkways on both sides of four-foot-wide beds. Create shaded areas in the garden using trellises, gazebos, and small trees so you can get out of the sun a while. Benches provide a comfortable place to sit and rest.

Walkways should be wide and level enough to accommodate a wheelchair. Turf, smooth recessed stepping stones, or paving stones make a good surface for wheelchair access. Mulch and loose gravel are often hard to push through and can also become a slipping hazard.

Smaller garden areas can be created using a number of large containers grouped together or as single planters.

Container Gardening

container gardening

Container gardening can reducing your gardening stress, and the many different and attractive containers available add interesting focal points to your garden.

You can also turn just about anything into a container garden. From teapots to milk jugs, wooden dressers to wine barrels, let your creativity run wild!

Raised Bed Gardening

Consider installing raised beds that reduce bending over by allowing you to work in a standing or seated position. Standing, you may be able to maintain a three-foot-deep bed, while two feet is manageable if seated.

raised bed gardening

Raised beds can be a very attractive part of a landscape, defining walkways and providing a more formal appearance. Height often varies from six inches to three feet tall. Raised beds can be constructed in many styles using a wide variety of materials, including treated wood, concrete blocks, stone, and more. Various shapes and curves can be included to help blend the raised garden into your existing landscape, making it both attractive and functional.

Vertical Gardening

Unique garden features like vertical gardening with wall planters and trellises allow you to work while standing up. You can buy a premade trellis or build one yourself. Pots can be stacked or arranged on a riser. Like container gardening, vertical gardening is an opportunity to get creative in the garden.

vertical gardening ideas

Growing vegetables using vertical trellises reduces bending and picking. Many vegetables grow well when trellised. Cucumbers, beans, squash, and melons can all climb the traditional store-bought garden trellis.

Straw Bale Gardening

Another simplified gardening method that lifts your garden, making it more accessible, is straw bale gardening. This gardening method can be incredibly productive. It also cuts out all of the digging and cultivating that can be hard on the body. Straw bale gardening does, however, require several weeks of setup. A good guidebook is Straw Bale Gardens – The Breakthrough Method for Growing Vegetables Anywhere, Earlier and With No Weeding by Joel Karsten.

Reduce Your Garden Stress

Every garden and every gardener is unique. Consider your body type and abilities when adapting your garden as you age. Understand that your garden is limited by your physical abilities and personal interests as well as the location of the garden itself.

  • Reduce the overall size of the garden
  • Trade out high maintenance annuals and perennials for lower maintenance shrubs and trees
  • Reduce the amount of reaching, leaning, and bending with raised bed and vertical gardens
  • Garden small with container gardening
  • Keep your tools in good shape so they’re easier to work with

With these tips in mind, make changes that allow you to continue enjoying your gardening hobby without the stress of a high-maintenance landscape.

Vegetable Garden Preparation

The following Horticulture article printed in the Spring 2017 edition of the quarterly Oldham County Extension newsletter.

Looking Forward to the Vegetable Garden

Spring is almost here. Take advantage of the last few days of winter to plan your garden. After exploring the seed catalogs and deciding what you want to grow, map out your garden on paper. This is a good way to determine how much seed to order for the vegetables you want to produce. Whether you are growing a new garden or one you have been using for several years, planning will help improve the quality of your harvest this year and future years.

  • Plan your garden on paper before you begin. A map showing where each vegetable is grown allows you to space your plants for good growth. This plan will help determine your crop rotation for following seasons to reduce the carryover of vegetable disease and insect pests in the soil.
  • A good gardening site has full sun for at least eight hours each day and is relatively level, well-drained, and close to a water source. Watch for possible shading as landscape trees mature.
  • Test your soil every two to three years. Prepare the soil properly and add fertilizer and lime or sulfur according to soil test recommendations.

carrot vegetable garden

  • Plan only as large a garden as you can easily maintain. It is easy to overplant and then fail because it is hard to keep up with the tasks required.
  • Grow vegetables that will produce the maximum amount of food in the space available. The bush varieties are best for small spaces and generally yield a lot of vegetables.
  • Plant during the correct season for the crop. Crops are either cool season or warm season types. Choose varieties recommended for your area. Controlling weeds and watering when needed will keep the plants less stressed and improve your production.
  • Harvest vegetables at their proper stage of maturity. Store them promptly and properly if you do not use them immediately.

A well-planned and properly kept garden should produce 600 to 700 pounds of produce per 1,000 square feet and may include many different crops.

Finally, the closer the vegetable garden is to your back door, the more you will use it. You can see when your crops are at their peaks and can take maximum advantage of their freshness. In addition, keeping up with the planting, weeding, watering, and pest control will be easier.

Kentucky Native Fruit Trees

Fruit Trees Native to Kentucky

Apples, bananas, oranges, pears, peaches, and grapes ─ we eat these common fruits every day. Local sources for these fruits, however, can be difficult to find due to their preference for a longer, warmer growing season. Kentucky native fruit trees are adapted to grow in our varying soil types and withstand our unpredictable weather.

KY Native Fruit Trees

KY native plum

American Plum (Prunus americana)

The winter-hardy American Plum is a small tree, reaching a mature height of only fifteen feet. It grows wild across the eastern two-thirds of North America, forming thorny thickets that provide habitats for birds and other wildlife. The red to yellow fruit is popular with deer as well as humans. Kentucky plums can be eaten fresh or using in baking and canning. Due to unreliability of fruit production in Kentucky, plums are usually only commercially grown as a secondary crop.

Other names for the American Plum include American wild plum, Osage plum, river plum, thorn plum, wild yellow plum, red plum, August plum, and goose plum.

KY black cherry tree

Black Cherry (Prunus serotina)

The Black Cherry Tree produces Kentucky’s largest cherries which ripen in August and September. The bitter-sweet fruit is popular for jelly and wine making. Birds help spread Black Cherry seeds, but it also readily self-seeds. It can tolerant a wide variety of soils and conditions, the exception being full shade. Mature trees often reach a height of fifty to sixty feet. Black Cherry wood is hard, close-grained, and strong, making it popular in woodworking.

Farmers should note that this tree’s bark, leaves, and twigs are poisonous to livestock. Deer, however, can eat the leaves without problem.

KY native pawpaw fruit

Pawpaw (Asimina triloba)

Found in wooded areas, the Kentucky native Pawpaw is the largest native fruit in North America. Pawpaws are commonly described as tasting like a mix of banana and mango or pineapple. The fruit has high nutritional value, being an excellent source of vitamin A, vitamin C, and protein. Pawpaw fruit surpass apples, grapes, and peaches in magnesium, phosphorus, potassium, and sulfur. Wildlife such as birds, raccoons, and opossums enjoy the fruit, and zebra swallowtail butterfly larva feed on young pawpaw foliage. With some effort, you can grow pawpaws from seed.

Most pawpaw trees grow fifteen to twenty feet in height but can reach up to forty feet if conditions are optimal. The champion Kentucky pawpaw is in Letcher County.

Kentucky State University, one of Kentucky’s land-grant universities, is home to the world’s only full-time pawpaw research program. In 2009, the horticulture program released ‘KSU-Atwood,’ a new pawpaw variety named after Rufus B. Atwood who served as college presdent from 1929 to 1962. This variety is a heavy producer ─ more than 150 fruits from a single tree!

KY native persimmon

Persimmon (Diospyros virginiana)

Native Persimmon trees grow in Kentucky’s woodlands. Tolerating a range of pH levels, persimmons prefer moist, well-drained soil but can flourish in dry areas as well. Its interesting bark is thick, grey to black in color, and broken up in scaly, square blocks. The wood is very hard and has found use as golf clubs and flooring. When the berry ripens in the fall, the skin turns wrinkly, and persimmons become edible to humans. Persimmons taste similar to dates and can be used in breads, cakes, puddings, and beverages. You can also eat persimmons fresh or dried.

Cooking oil can be extracted from persimmon seeds. During the Civil War, Confederate soldiers boiled the seeds in substitution for coffee.

Winter-hardy and adaptable, Kentucky persimmon trees suffer few pests and diseases. Some trees further south may be susceptible to vascular wilt. It can develop black leaf spot, and tent caterpillars can be problematic.

KY native sassafras

Sassafras (Sassafras albidum)

Common across Kentucky, Native Sassafras is readily seeded by birds which love its fruit. The dark blue berries contrast beautifully to the bright red stems on which they grow. Sassafras trees thrive in moist, well-drained, acidic soil with full sun to partial shade but can also tolerate drier, rockier soil. Filé, a Creole spice used in gumbo, is made by grinding dried sassafras leaves. The fragrant bark and roots have been used to make tea and root beer but contain an oil called safrole, a proven carcinogen in mice and rats. In 1960, the Food and Drug Administration banned direct use of safrole in food although spices are still permissible.

Most sassafras trees mature to a height of thirty to sixty feet with a spread of twenty-five to forty feet. The national champion sassafras ─ located in Owensboro, Kentucky ─ is seventy-eight feet tall with a sixty-nine-foot spread.

KY Native Berry Fruits

KY native elderberry

American Black Elderberry (Sambucus canadensis)

Only four to twelve feet in height, the American Black Elderberry forms thickets that provide habitat to more than fifty species of birds and small mammals. White-tailed deer feed on the twigs, foliage, and fruit. Purple-black American elderberries taste slightly bitter and make a crimson juice, finding use in wine, jellies, and pies. The shrub grows best in full sun but can also be found along streams and on forest floors. Its hard wood can be crafted into combs, spindles, and pegs. The twigs can fruit are also used as dyes in basket-making.

Elderberry trees grow best from seed which must be scarified prior to planting due to the hard seed coat. Without scarification, the seed may not germinate for two to five years after planting. The hard coat protects the seed when wildlife ingest the fruit. If properly stored, elderberry seeds may remain viable for up to sixteen years.

KY native mulberry tree

Red Mulberry (Morus rubra)

Hardy Red Mulberry trees prefer full sun but will tolerate shade as well as a variety of soil and weather conditions. They thrive in moist, deep, rich soil. Birds love the sweet fruit which resemble thin blackberries. Red mulberries can be eaten fresh or used in jellies, wines, and desserts. These native trees can grow over sixty feet tall and require heavy pruning to maintain a suitable height for fruit harvest, so red mulberry trees are not commercially grown for fruit production. Some varieties, however, are grown for their ornamental value.

The mulberry, once known as the “King of the Tree Crops,” is now considered a messy, weedy tree unsuitable for the well-manicured landscape.

KY Native Serviceberry

Downy Serviceberry (Amelanchier arborea)

Of the three Kentucky native serviceberries, Downy Serviceberry is mainly planted as an ornamental. Its wood is both heavy (the heaviest in the U.S.) and hard, making excellent tool handles. Serviceberry trees grow in full sun or partial shade and prefer moist but well-drained soil. The red-purple fruit tastes somewhat like blueberries. Serviceberries can be eaten fresh, baked in pies, or dried like raisins. Forty or more bird species favor serviceberries as well as mammals big and small. It is a common understory tree.

The serviceberry gets its name from funeral/memorial services. Kentucky serviceberries flower in early spring (two weeks before the dogwood) and has been used as an indicator, legend has it, that it is warm enough outside to dig a grave for a funeral service. The nickname “sarvisberry” comes from the Appalachian pronunciation of the word “service” as “sarvis.”

KY Native Plants in Bloom

Home to over twenty-five hundred plant species, Kentucky is a veritable wildflower garden. Kentucky native fall flowers include aster, goldenrod, and ironweed.

KY native aster

Aster

Fall Kentucky Native Flower

Several species of aster grow in Kentucky, including smooth blue aster, aromatic aster, New England aster, and white panicle aster.

Kentucky asters bloom from summer to fall in multiple colors: violet, white, blue, and pink. Depending on species and variety, they can grow from eighteen inches to five feet tall. Height can be controlled by pruning during summer, before buds develop. Be careful to remove no more than one-fourth of the total height at a time so as not to overstress the plants.

Asters are prone to powdery mildew and verticillium wilt, especially when overcrowded. Prevent these diseases by providing the plants with good air movement. Asters grow best in full sun but can tolerate partial shade.

KY native goldenrod

Goldenrod (Solidago)

Kentucky Native Flower in Bloom

Goldenrod, Kentucky’s state flower, blooms in the late summer and early fall. Thirty-one species of goldenrod are native to Kentucky, including two endangered species: White-Haired Goldenrod and Short’s Goldenrod.

It is a common misconception that goldenrod is responsible for fall allergies. In truth, it is the inconspicuous ragweed, blooming at the same time, that causes hay fever. Green and weedy in appearance, ragweed blends right into its surroundings. Its tiny, green flowers release waves of pollen into the air, contributing largely to fall allergies. Goldenrod, on the other hand, is insect-pollinated and therefore not the culprit of your allergic reaction.

Goldenrod blooms in full sun from late summer to early fall. Species vary from two to five feet in height. Some varieties will aggressively take over a garden, so goldenrod is not a common landscape plant. They are susceptible to several diseases, but most are easily avoidable if proper air circulation is provided and good watering practices are used.

KY native ironweed

Ironweed (Vernonia)

Kentucky Native Wildflower

From late summer through early fall, ironweed blooms in fields and along roads all across Kentucky. The most common species in the state is Tall Ironweed, but Missouri Ironweed and New York Ironweed also grow in some regions.

Ironweed can grow between four and six feet tall, but pruning in June can help keep the size manageable. It prefers growing in full sun and well-drained, moist soil. Few pests and diseases affect this Kentucky native wildflower. With an aggressively spreading root system, ironweed is perhaps the most troublesome pasture weed in Kentucky. Livestock avoid it due to its bitter taste.

Top 5 Landscaping Mistakes

The following Agriculture & Natural Resources article printed in the quarterly Oldham County Extension newsletter.

Common Landscaping Mistakes

Horticulturist Michael Boice Shares His Expertise

Planting and managing a landscape incorrectly can lead to plant loss or excessive maintenance. Often we plan a landscape without thinking about the needs of plants or how they grow. Five of the most common mistakes I have found include locating a plant in a space that is too small for it, planting in poor soil types, overplanting, improper mulching, and failing to consider the environmental requirements of the plant.

Trees are often planted in locations they will rapidly outgrow. Even small trees grow 15 to 25 feet tall and 10 feet wide and can interfere with buildings and walkway. Heavy pruning to control the size will eventually stress the tree, making it susceptible to disease and insect pests.

Some locations have poor soil that will not support the plants we choose. Note that water-retaining soils are the most common type in our area, and too much water can drown a root system. Root health is very important to the growth of a plant. Some sites may require total removal of poor soil and replacement with a good quality topsoil to insure proper drainage.

ky landscaping

Overplanting is a common error. It may be desirable for a new planting to look full, so small plants are planted for the immediate aesthetics without considering how big they will grow in a couple years. Overplanting requires a lot of trimming to maintain plant size because crowded plants will grow taller. Crowding also reduces air movement, increasing the opportunity for disease and insects to attack. Plants often have to be removed to reduce the overcrowded look or even to uncover a blocked window. Reduce the maintenance and improve the health of your landscape by considering how much space a plant will require once it is mature.

Proper mulching is good for the landscape. Mulch improves the appearance, conserves moisture, and reduces the number of weeds. Mulch can also cause problems if applied incorrectly. Mulch should be applied a uniform two to three inches deep around the planting. It should not be excessively deep or piled up on plant stems or trunks. Deep mulch can shed water, limit air reaching the roots, and create homes for rodents and insects that can damage the plants. Mulch piled up around tree trunks creates an area where roots will grow in the mulch and wrap around the tree. Over the years, the roots grow toward the trunk and girdle the tree, killing it. Maple trees are especially prone to girdling roots.

Plants used in landscaping come from many different growing environments. Plants chosen to add color or texture are often placed in locations that are too sunny or too shady for them. The plants become stressed, making them more susceptible to pests. Some plant foliage, such as that of the variegated hosta, will burn in sunny locations. Most flowering plants will not flower in heavy shade. The amount of light and water available, soil type, and growing temperature are important for the health of the planting.

Planting Summer Annual Forage Crops: Grower Talk

There’s still time to plant summer annual forages for pasture and hay this season. Forages like sorghum-sudangrass, millet and teff are typically planted in May through July. The earlier these are planted during this time window, the higher the yield opportunities. Summer annuals make their best growth when cool season grasses have gone semi-dormant during hot, dry months. Read on to learn from two producers about their experiences with these forage crops.

Wes Husband, on growing German Millet (also called Foxtail Millet):

“I have grown German/Foxtail millet for hay and have always been lucky enough to have a good crop. One year we had it tested, and it was 14% crude protein. That year I cut it right when it was in the boot.” (before seed heads form)

“I started using millet frequently for two reasons. I plant/reseed hay fields in the fall because there are less weed problems then. I use the millet during the summer growing season to prep the ground for working in the fall and suppression of weeds during the growing season. Millet seems to have the same effect on ground as soybeans. After I harvest the millet the ground really works up well.”

“I have been double-cropping the millet behind wheat. Once the wheat is harvested, I plant millet to make sure I have enough hay. Last year it rained so much, and it became so late with the wheat harvest that I didn’t plant millet until the third week in July and still had a harvestable crop.”

“Advantages include low seed cost, minimal rainfall requirements, high yields, and minimal fertilizer needs. It is excellent for an emergency late planted hay crop and has a short growing season. If there is a disadvantage I guess it would be that it’s an annual.”

Caldwell Willig, on growing Sorghum-Sudangrass and Teff:

“We had a river bottom that wasn’t fenced and couldn’t be grazed. It was cropped for years (grain) but we still had to buy hay to supplement what we cut on the rest of the farm. So the economics of leasing the bottom and turning around and buying hay just didn’t make sense. We already had the investment in the hay equipment so we decided to convert the bottom to hay ground.”

“The advantage of using sorghum-sudangrass and teff was the increased tonnage/acre yields. As far as disadvantages – like all hay, timing is everything. Teff was very prone to lodging, particularly right before cutting. A sudden shower with some wind meant disaster when we grew it.” (Especially prone to lodging after stem elongation/seed formation).

“Excessive rainfall right before harvest of sorghum-sudangrass results in the plants over-maturing very quickly and producing thick, unpalatable stems. Also, the sorghum-sudangrass is very difficult to dry down sufficiently to make good quality hay. It makes better baleage.” This year, Caldwell planted sorghum-sudangrass on a different part of the farm, where it could be grazed by cattle.

Note that horses should not be allowed to graze sorghum-sudangrass or millet pastures because of serious health disorders associated with these. When in doubt about suitable forages for grazing animals, check with the Extension Office and/or your veterinarian.
