Preserving Garden Tools

Picture
​Hoes, shovels and other common garden tools often have wooden handles that can deteriorate over time. Storing tools in a protected location can slow that process, but normal use will still expose the tools to the elements. The end of the season is a good time to clean up and protect the handles so they will last for many years. Weathering can raise the grain of wood, resulting in splinters. A light sanding can smooth the handle. Follow that with a light application of wood preservative, linseed oil or polyurethane to protect the wood. Wipe off any excess after a few minutes as oil-based products can attract dirt. Cleaning any dirt off metal parts and coating with a light application of oil can prevent rust. Good tools are expensive. A few minutes of care after the season is over can help preserve them for many years to come. (Ward Upham)

Cleaning Extends the Life of Garden Tools​

Vegetables:
Soil Prep Now for Peas Next Spring

Picture
 Peas can be planted earlier in the spring than just about any other vegetable crop because they can grow well at a soil temperature of 40 degrees. Though other crops such  as lettuce, parsnips and spinach can sprout at lower temperatures (35 degrees), they don’t start growing well until the soil reaches about 45 degrees. However, soils are often too wet to work in the spring. Therefore, you may wish to prepare the soil now rather than next spring so that planting can take place as early as possible even if those spring soils are wet. Wait until soil temperatures reach 40 degrees next spring and sprinkle the seeds on the soil and push them in with your finger. Protection from rabbits and deer will probably be needed as they will be attracted to anything green coming up so early. (Ward Upham)

Flowers:
Fall Care of Peonies

Picture
Cut peony foliage back to the ground if this hasn’t been done already. Compost or discard foliage. Fertilize peonies twice a year — in the spring shortly before new growth appears and then again in the fall after the plants have been cut back. A total of 1.5 to 2 ounces (3 to 4 tablespoons) of a 1-1-1 fertilizer such as a 10-10-10 or 13-13-13 per plant per application should be used. This amounts to 3 to 4 ounces of fertilizer per year. If a soil test reveals adequate levels of phosphorus and potassium, use a lawn fertilizer such as a 29-5-4, 27-3-3 or something similar, but cut the rate to 1/3 of the above rate. In other words apply ½ to 3/4 ounce (1 to 1.5 tablespoons) per plant. The lawn fertilizer should not be a “weed and feed.”
 
Never apply fertilizer directly on the center of the peony as the buds (eyes) may be damaged. Rather, place the fertilizer in a band from 8 to 18 inches from the center of the plant.  Water the fertilizer in so the plant can take it up.
 
Winter protection of herbaceous peonies is only necessary the first winter after planting to prevent alternate freezing and thawing from lifting plants out of the soil. A couple of inches of mulch should be sufficient. Any organic material that does not mat down will work and should be applied after the ground freezes. Avoid using leaves that will mat together. Remove the covering before growth begins in the spring.
 
The less common tree peonies have woody stems like deciduous shrubs and should not be cut back to the ground or pruned in the fall. Collect the shed leaves and place in the compost pile this fall. Though tree peonies are hardy to Zone 4, they do benefit from a light mulching over winter. Also, it is recommended that tree peonies be fertilized during November to get the plants off to a good start next spring. It is best to take a soil test to see what nutrients are needed. If the soil needs phosphorus and potassium, use a complete fertilizer (such as 10-10-10, 9-9-6, etc.) at the rate of 2.5 pounds per 100 square feet. This would equal 1 rounded teaspoon per square foot.
 
If phosphorus and potassium are not needed, blood meal makes an excellent fertilizer. Apply at the rate of 2 pounds per 100 square feet or 1 teaspoon per square foot. Turf fertilizers such as a 27-3-3 or 30-3-3 also can be used but at the rate of to 1 pound per 100 square feet or 1 teaspoon per 2 square feet. (Ward Upham)

Miscellaneous:
Begin Rabbit Protection Now

Picture
Rabbits may begin to nibble on newly planted trees and shrubs through the winter. Protect your investment with at least 2-foot-tall cylinders of 1-inch-mesh, chicken wire, or similar barrier.  Other control methods include plastic tree wraps and liquid rabbit repellents sprayed on the plants. Repellents will need to be reapplied each time it rains.  (Ward Upham)

Horseradish

Picture
Horseradish is ready to dig after a hard freeze kills the foliage (usually November or December). The large roots can be harvested while smaller, pencil sized roots can be cut in 6-8 inch long sections as 'seed' or 'sets' for next year's crop which are then immediately re-planted. Another option is to leave the horseradish in the ground and dig as needed. If you choose the latter option, be sure to heavily mulch the area so that the ground doesn’t freeze.

To use horseradish, peel the large, fleshy roots and cut into sections. Use a blender or food processor to chop the roots along with a small amount of water and a couple of ice cubes. Vinegar or lemon juice is added to stop the process that produces the “bite” of horseradish. Add immediately after blending for a mild flavor or wait up to 3 minutes to give the horseradish more kick. Use 2 to 3 tablespoons of vinegar or lemon juice per cup of horseradish sauce along with ½ teaspoon of salt for flavor.
 
Horseradish has an extremely strong odor and so you may wish to open the blender or food processor outdoors and to keep your face away from the container when opening. Store ground horseradish in a tightly sealed jar in a refrigerator until ready for use. (Ward Upham)

Knotweed Control

Picture
Knotweed thrives in compacted soils, so a thorough aeration is the first step in control. This weed will not compete in a healthy lawn. Chemically, there are two options. Knotweed is an annual that germinates in late February or early March, so a preemergence herbicide can be used in the late fall (about now). Pendimethalin (Scotts Halts), Surflan (Weed Impede), Barricade, Dimension and XL are labeled for knotweed. (Note: Pendimethalin, Barricade and Dimension can be used on all Kansas turfgrasses, while Surflan and XL can only be used on tall fescue and warm-season grasses such as buffalograss, zoysiagrass and bermuda).
 
The other option is to use a combination postemergence product such as Trimec, Weed-Out, Weed-B-Gon or Weed Free Zone after the knotweed has germinated in the spring but is still young.
 
​If spring seeding of the lawn is planned, your options are more limited. Buctril can be used on commercial sites and has a very short residual. It must be used on very young knotweed to get control. Trimec and others require a month before overseeding to thicken up your lawn. Obviously, don't use a preemergence herbicide if you are trying to get new seed established. For homeowners seeding in the spring, tilling will control knotweed adequately without using a herbicide. If seeding without tilling (e.g., overseeding using a slicer-seeder), then use a combination product such as one mentioned above just after the knotweed comes up in the spring, and be sure to wait at least a month before seeding. (Ward Upham)

Potential Problems with a Warm Fall

Picture
In the fall plants go through a process of cold hardening whereby they become acclimated to low temperatures. This acclimation is in response to cooler temperatures and to days becoming shorter during the fall months. As temperatures drop gradually, plants become progressively more acclimated to cold. A well-acclimated plant can survive much lower temperatures than one that has not had the opportunity to become used to the cold weather. The temperatures recently have been so mild that our plants have not hardened as much as they normally would. If temperatures drop very quickly, we may see damage to plants.
 
There is not a lot that can be done to protect trees and most shrubs (other than making sure the soil under them is moist) but we may be able to help herbaceous perennials. Herbaceous perennials would not only include our perennial flowering plants that die to the ground each year but also other plants such as strawberries. As long as the weather remains mild or temperatures drop gradually, keep the plants uncovered to allow them to acclimate. However, if there is a sharp drop in temperature (to mid-teens or lower), throw mulch or some other covering over them to help moderate temperatures. Uncover again as temperature rise to allow the plants to continue the acclimation process. Some tender herbaceous perennials (such as strawberries) need a permanent mulch through the winter months to help protect them from dessication and heaving caused by freezing and thawing of the soil. This is best done when temperatures have been cold enough to leave some frost in the ground. (Ward Upham)

Fall Colors of Trees

Picture
Part of the allure of fall foliage is color variation. There are trees that turn red, purple, yellow, orange and brown.
 
Specific plant pigments determine individual colors. Foliage derives its normal green color from chlorophyll, the substance that captures the energy of the sun. Other pigments produce fall colors. Reds and purples are caused by anthocyanins, yellows by xanthophylls, and oranges by a combination of carotenes and xanthophylls. Browns are the result of tannins present in the leaf. Most of these substances are present throughout the growing season but are masked by the green color produced by chlorophyll. Anthocyanins are the exception and are produced after the chlorophyll is destroyed in the fall.
 
If you have ever seen pictures of New England in the fall, you have probably wondered why trees in Kansas usually do not color as well. This difference is partly because of the tree species prevalent in New England. Certain oaks and maples naturally produce good color. Coloring also is influenced by the weather.
 
Warm, sunny days and cool nights are ideal for good color. The sunny days encourage photosynthesis and, thus, sugar accumulation in the leaves. As fall progresses, each leaf develops an abscission layer at the base of the petiole, or leaf stem, that prevents these sugars from being transported down the trunk to the roots for storage. This high sugar content in the leaves produces more intense colors. Cloudy days and warm nights prevent some of the sugar accumulation in the leaves and results in less vibrant colors.
 
Weather during other parts of the growing season also can have an effect. Heavy rains in the early spring or hot, dry weather during the summer can both have a deleterious effect on fall color.
 
The length of time a tree maintains fall color also depends on weather. Reds, yellows and oranges are short-lived when trees undergo frosts and freezes. (Ward Upham)

Flowers:
There is Still Time to Plant Spring-Flowering Bulbs

Picture
Generally, it is recommended to plant hardy bulbs (especially daffodils) in October to give them enough time to root before winter. But it is certainly not too late to plant them now. As long as the soil temperatures are above 40 degrees F, the bulbs should continue root development. You can find the previous week’s soil temperature readings for areas across the state from our Weather Data Library at  http://mesonet.k-state.edu/weather/soil/
 
Although many of the best bulbs have probably already been purchased, garden centers may still have a good selection. Be sure to select large, firm bulbs that have not begun to sprout. While many bulbs can adapt to a wide range of soil types, none can tolerate poorly drained soil. Prepare the planting bed by adding organic matter such as peat moss, well-rotted manure, or compost and mix into the soil.
 
Adequate fertility is essential. It is best to rely on a soil test to determine what nutrients are needed. Garden soils that have been fertilized regularly in the past may have excess levels of phosphorus. Excess phosphorus can interfere with the uptake of other essential micronutrients. In such cases, it would be better to use a fertilizer relatively high in nitrogen such as a 29-5-4, 27-3-3, or something similar. Apply these fertilizers at the rate of 2/3 pound per 100 square feet. Organic sources of fertilizers low in phosphorus include blood meal (12-0-0) applied at 5 to 10 pounds per 100 square feet, cottonseed meal (6-0.4-1.5) applied at the rate of 10 pounds per 100 square feet and soybean meal (7-2-1) applied at the rate of 8 pounds per 100 square feet.
 
In the absence of a soil test, or if phosphorus is needed, add a low analysis, balanced fertilizer such as 5-10-5 or 6-10-4 at the rate of 2 to 3 pounds per 100 square feet of bed. Mix all amendments thoroughly with the soil before planting the bulbs.
 
The size and species of the bulb determine how deep to plant. In general, the depth to the bottom of the bulb should be about 2 to 3 times the size of the bulb, but check the planting instructions specific to each particular flower. (Ward Upham)

Perennial Garden Clean-Up

Picture
Fall is traditionally a time for cleaning up gardens. Normally, we recommend clear-cutting dead stems to help control insect and disease problems. With herbaceous perennials that have been pest free, you might want to consider leaving some to provide structure, form, and color to the winter garden. For example, ornamental grasses can be attractive even during the winter months. But those near structures should be cut to the ground because they can be a fire hazard. Perennials with evergreen or semi-evergreen foliage can provide color. Of course, some perennials are naturally messy after dormancy and should be cut back in the fall.

Foliage can be left for other reasons. For example, foliage left on marginally hardy plants such as tender ferns helps ensure overwintering of plant crowns. Also, seed heads on some perennial plants can provide seed for birds. (Ward Upham)

Miscellaneous:
Harvesting and Curing Black Walnuts

Picture
Black walnuts are ready to be harvested when the hull can be dented with your thumb. You can also wait until the nuts start falling from the tree. Either way it is important to hull walnuts soon after harvest. If not removed, the hull will leach a stain through the nut and into the meat. The stain will not only discolor the meats but also give them an off flavor.
 
There are several ways to hull walnuts including running them through a corn sheller or pounding each nut through a
hole in a board.  The hole must be big enough for the nut but smaller than the hull. An easier way is to run over the nuts with a lawn tractor.  This will break the hull but not crack the nut.
 
Note that walnut hulls contain a dye that will stain concrete, your hands or about anything else it touches.  Wear gloves as the stain is almost impossible to remove.
 
Wash hulled nuts by spreading them out on the lawn or on a wire mesh and spraying them with water or placing them in a tub of water. If you place them in a tub, the good nuts should sink. Those that float are probably not well-filled with kernels. Next, dry the nuts by spreading them in layers no more than three deep in a cool, shady and dry place such as a garage or tool shed. Drying normally takes two weeks. (Ward Upham)

Will Fall Mums Last Through the Winter?

Turfgrass:
Apply Late-Season Nitrogen Application in November

applying fertilizer to turf
November is the time to give cool-season lawns the last nitrogen application of the season. Why November? Because while top growth slows in response to cool temperatures, grass plants are still making food (carbohydrates) by photosynthesis. A November nitrogen application helps boost the photosynthesis rate. Carbohydrates that are not used in growth are stored in the crown and other storage tissues in the plant. These carbohydrate reserves help the turfgrass green up earlier in the spring and sustain growth into May without the need for early-spring (March or April) nitrogen. Those early-spring nitrogen applications are less desirable because they can lead to excessive shoot growth and reduced root growth. Other benefits of November-applied nitrogen for cool-season grasses include improved winter hardiness, root growth and shoot density.
 
How much should you apply? One to 1 to 1 ½ pounds actual nitrogen per 1,000 sq. ft. of lawn area is sufficient. Following the recommended spreader setting on the fertilizer bag should apply the correct amount of fertilizer.   In order for this application to be effective, the nitrogen must be readily available to the plant, because the growing season is nearly over. Therefore, for a November application, use a soluble (quickly-available) nitrogen carrier such as urea or ammonium sulfate.
 
Many turfgrass fertilizers sold in garden centers and other retail outlets also contain soluble nitrogen. Avoid products that contain water-insoluble nitrogen (slow-release) for this application. As always, sweep up any fertilizer that gets on driveways, sidewalks, or streets and reapply it to the lawn. (Ward Upham)

Flowers:
Garden Mums

garden mums
​As soon as garden chrysanthemums are done flowering, you may cut the plants back to 2 to 3 inches high. Some gardeners prefer to leave the top growth so that it provides some protection from fluctuating soil temperatures. If you choose to cut the tops off, apply a layer of mulch over the top of your mums after the ground has frozen or if the forecast calls for a sharp drop in temperature. Mums should not completely dry out during the winter. It may be necessary to water occasionally if sufficient rain or snow has not fallen. (Ward Upham)

What is the "Wild" Shrub with the Bright Red Berries?

Honeysuckle
People in the eastern half of the state have been reporting shrubs with bright red berries growing wild. The berries are clustered around the stem and the leaves are still a bright green color. These are likely one of two species of bush honeysuckle, Amur or Tatarian. Each species can reach 6 to 20 feet tall.
 
This landscape shrub has become a serious understory invasive throughout the Midwest from eastern Kansas to Ohio. Many states have it on their noxious weeds list. All of our native honeysuckles are vines, similar to the vining Japanese honeysuckle. Amur and Tatarian honeysuckles are very noticeable in the spring as they put out leaves earlier than most other trees and shrubs. Leaves also stay green much later into the fall. This long growing season gives it a competitive advantage over other native species, and the vigorous growth can take over a woodland understory, reducing the number of native woodland wildflowers and other shrubs. If you want to promote native species on your property, then controlling bush honeysuckles is needed. Honeysuckle seedlings can be readily hand pulled when the soil is damp.
 
Chemical control is needed for larger infestations, as cutting alone results in vigorous resprouting. Foliar applications of glyphosate (i.e., Roundup) in late summer and fall works well as does applications of Crossbow (2,4-D + triclopyr). Treating cut stumps with Tordon RTU (picloram), or concentrated (20% - 50%) glyphosate is also quite effective. Several studies have shown basal spraying with triclopyr (Garlon) not to be effective, while basal applications with 2,4-D or picloram products work well, using an oil carrier to penetrate the bark. Please follow all label instructions when using pesticides. (Charlie Barden and Ward Upham)

Tucking your Lawnmower in for the Winter

Picture
If you are done mowing for the year, be sure to service your mower before putting it away. Make sure you drain the gas tank of gasoline-powered engines or use a gasoline stabilizer. Untreated gasoline can become thick and gummy. A few drops of oil squirted inside the spark plug hole (after you remove the spark plug) will help lubricate the cylinder. While you have the spark plug removed, replace it with a new one. If your equipment has a battery, clean the battery terminals, which usually corrode during the season. A wire-bristle brush is a good tool for doing this. The battery can then be removed or connected to a battery monitor that will keep it charged over winter. If you remove the battery, be sure to store it in a protected location for the winter (a cool basement works best).

Now is also an excellent time to sharpen mower blades so they'll be ready next spring.  Sharpening rotary mower blades is fairly straightforward. The following steps will guide you through this process:

        * Check the blade for major damage. If you can't fix it, it likely will need to be replaced.
        * Remove grass and debris from the blade with a moist cloth. Dry before beginning to sharpen the cutting edge.
        * Remove nicks from the cutting edge, using a grinding wheel or hand-file.
        * If using a grinding wheel, match the existing edge angle to the wheel. If hand-filing, file at the same angle as the existing edge.
        * Grind or file until the edge is 1/32 inch, about the size of a period.
        * Particularly with a grinding wheel, avoid overheating the blade as this may warp it.
        * Clean the blade with solvent or oil, much like if you were cleaning a gun, for optimum winter storage. Avoid using water because it will promote rust.

Following these tips can help you better prepare your mower for winter storage and also save you some steps this coming spring. (Ward Upham)

Pests:
Millipede Invasion

Picture
Millipedes, or "thousand-legged worms," are an arthropod relative of insects. They can be distinguished from centipedes by the number of legs per body segment. Millipedes have four legs per segment, while centipedes have only two. Also, the millipedes’ legs are quite short and often are not seen if viewing the millipede from above. Though usually found in damp locations outside, they can become a problem inside the house and cause homeowners a great deal of concern.

Household invasions are often sudden and sporadic and may be in response to rain. Millipedes feed primarily on decaying organic material, rarely on living tissue. They do not bite people or damage household furnishings directly, but they will leave a mess and give off an odor if crushed.

Millipedes are worm-like and most often brownish-black in color. The legs ripple as they move.  Millipedes often curl up into a "C" shape like a watch spring if touched. Remember you may not see the legs unless viewing the millipede from the side. They defend themselves by releasing a disagreeable odor when disturbed.

Millipedes require high moisture to survive and often die in a day or two after entering a house. Dead millipede bodies can then be vacuumed up and disposed of. Drying out moist areas inside will also help with control. Sealing and caulking around openings in the foundation will help keep populations low. If this is not enough, spraying cyfluthrin (Home Pest Control Indoor & Outdoor Insect Killer), proxopur (Baygon), or resmethrin in a three-foot band around the outside of the house will take care of them before they get inside. (Ward Upham)

Hackberry Psyllids Flying Around Homes

Picture
The hackberry psyllid causes “bumps” to form on the underside of hackberry leaves early in the season. The bumps are actually caused by nymphs that hatch from eggs laid by females as leaves start to unfurl in the spring.  This abnormal growth is caused by the feeding of the nymphs. This condition is extremely common to the point it can almost be used as an identifying characteristic for hackberry. Fortunately, this does not harm the hackberry.

The hackberry psyllid overwinters in the adult stage. These insects are tiny and resemble miniature cicadas. They are dark reddish-brown with mottled wings. Adults are tiny enough that they can crawl through the openings in most screens and therefore often find shelter during the winter inside houses. In the spring, the adults become active about the time the leaf buds of hackberry trees open. The best way to control hackberry psyllids found inside the home is the same as for boxelder bugs: a vacuum cleaner.

Several steps can be taken during the fall just before frost to reduce entry. Turning off outdoor night-lights and reducing the amount of light shining through night windows helps. Consider using fine mesh (18 mesh) screens on windows that are kept open. Ordinary screens are 12 mesh to the inch. Caulk or plug up cracks and crevices. Keep windows and doors closed when psyllids are active. For temporary reduction, spray exterior surfaces such as window screens, shutters and sides of buildings where psyllids are resting. Look for residual insect sprays labeled to use on outdoor surfaces. Examples of ingredients with residual action include cyfluthrin (Tempo, Bayer Vegetable and Garden Insect Spray), bifenthrin (Talstar, Hi-Yield Bug Blaster II), permethrin (numerous trade names), Baygon and tralomethrin.

Preserving Garden Tools

Picture
Hoes, shovels and other common garden tools often have wooden handles that can deteriorate over time. Storing tools in a protected location can slow that process, but normal use will still expose the tools to the elements. The end of the season is a good time to clean up and protect the handles so they will last for many years. Weathering can raise the grain of wood, resulting in splinters. A light sanding can smooth the handle. Follow that with a light application of wood preservative, linseed oil or polyurethane to protect the wood. Wipe off any excess after a few minutes as oil-based products can attract dirt. Cleaning any dirt off metal parts and coating with a light application of oil can prevent rust. Good tools are expensive. A few minutes of care after the season is over can help preserve them for many years to come. (Ward Upham)
