Many gardeners assume that compost is acidic but such is usually not the case.  Compost is more often alkaline than acidic.  The possible use of alkaline composts on highbush blueberries was enough of a problem that Oregon State University carried out a study that included determining the pH of various composts. The listing below is of some of the composts Oregon State University studied and the pH of those materials.  We have not listed those composted from materials not common in Kansas such as hops and mint hay.
 
Material                       pH
Mixed Manure                     7.9
Horse Manure                     6.4
Dairy Solids                          8.0
Leaf                                          7.2
Yard Debris                          7.7
Composted Bark                5.4

It is interesting to note the tremendous variability in pH; from 8.0 for dairy solids to 5.4 for composted bark. Therefore, it is important to perform a soil test on soils that have been heavily amended with compost as the compost may have affected the pH. (Ward Upham)

Turfgrass:
Dormant Seeding of Turfgrass

Picture
The best time to seed cool-season grasses such as tall fescue and Kentucky bluegrass is September because the turf has more time to mature before spring crabgrass germination and the heat stress of summer. Dormant seeding of turfgrass is sometimes used to help fill in bare spots of lawns that weren't overseeded in the fall. Dormant overseeding is done during the winter (December – February) when it is much too cold for germination.
 
As with any seeding program, good seed-soil contact is vital. Several methods can be used. One method is to seed when there has been a light snowfall of up to an inch. This is shallow enough that bare spots can still be seen. Spread seed by hand on areas that need thickening up. As the snow melts, it brings the seed into good contact with the soil where it will germinate in the spring.
 
Another method is dependent on the surface of the soil being moist followed by freezing weather. As moist soil freezes and thaws, small pockets are formed on the wet, bare soil that is perfect for catching and holding seed. As the soil dries, the pockets collapse and cover the seed.

​A third method involves core aerating, verticutting or hand raking and broadcasting seed immediately after. Of course, the soil must be dry enough and unfrozen for this to be practical. With any of the above methods, seed germinates in the spring as early as possible. There will be limitations on what herbicides can be used for weed control. Tupersan (siduron) can be used as a crabgrass preventer on new seedings even before they have come up. Also dithiopyr, found in Hi-Yield Turf and Ornamental Weed and Grass Stopper, can be used on tall fescue, Kentucky bluegrass, and perennial ryegrass two weeks after germination. Dithiopyr is longer lasting and more effective than siduron. Other preemergence herbicides available to homeowners require that the turf be well established before application. (Ward Upham)

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

Picture
People in the eastern third 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 Tartarian), which can get 6-20 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.  Bush honeysuckles are also noticeable in the spring as they put out leaves much 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.  Cut stump and basal treatments can be done when the areas to be sprayed are dry and not frozen. Please follow all label instructions when using pesticides. (Charlie Barden and Ward Upham)

Miscellaneous:
Compost Pile Maintenance

Picture
Compost piles should be turned about once per month even during the winter months. This will ensure the composting process continues and that all materials are equally composted. A compost pile is “turned’ when uncomposted material is moved from the sides and tops of the pile to the center where it provides “fuel” for the microorganisms that break it down. Water may need to be added if the material you move to the center is dry. Check the moisture content by squeezing a fistful in your hand. It should feel moist but no excess water should drip out. Compress the material in the pile as best you can as excess air can slow the composting process. (Ward Upham)

Poor Drainage in Garden Areas

Picture
Winter is often a good time to fix areas in the garden where water sits and does not drain properly. Such areas often harm plant roots due to poor oxygen levels in the soil. Consider adding good topsoil so water doesn’t sit. Be sure to till or spade the area to mix the new topsoil and the underlying existing soil. Plant roots do not like to cross distinct barriers caused by one type of soil sitting on top of another. Internal drainage can be improved by adding organic matter such as peat moss, rotted hay, cotton burrs, rotted silage or compost. This can be done by adding a 2- to 4- inch layer of organic matter to the surface of the soil and tilling or spading in as deeply as possible. (Ward Upham)

Winterizing Roses

Picture
Though most shrub roses are hardy in Kansas, other types of roses can be more tender. For example, the hybrid teas have certain species in their ancestry that originated in the warm climate of southern China. These roses need protection to reliably survive Kansas winters. Mound soil or compost about 8 to 10 inches high around each plant. If using soil, bring it in from another part of the garden. Do not pull it from between plants because this can damage the rose roots or make them more susceptible to cold.
 
Mounding is normally finished by Thanksgiving. After the ground has frozen, add a 4-inch mulch of straw, leaves or hay for further protection. More soil may be spread on top of the mulch to keep it in place. Do not add the mulch before the ground freezes or mice may invade and feed on the roses over the winter. The purpose of these coverings is not only to moderate the cold, but also to prevent warm days during the winter or early spring from stimulating growth that is tender to returning cold weather. Excessively tall canes should be pruned to a height of 36 inches and tied together to prevent them from being whipped by strong winter winds. Wind can damage the crown of the plant or loosen the surrounding soil.
 
Next spring, remove coverings before new growth starts. If soil was used for mounding, remove from the area so that the level of soil stays constant from year to year. Wait until after the ground thaws, or the tops may begin growing before the roots can provide water. (Ward Upham)

Miscellaneous:
Winter Care of Houseplants

Picture
During the short days of winter, houseplant growth slows, resulting in a need to change how we care for them. Although frequent watering may have been necessary during the long days of summer, the same amount now could cause problems. Excess water fills air spaces within the soil resulting in roots that receive less oxygen than they need. Water by touch, not by calendar.  If the soil is dry an inch deep, it istime to water. Be sure to add enough so that some water flows out the bottom of the pot. This will help wash out excess salts that tend to accumulate within the potting soil. Fertilization also should be reduced. Normally, it is best to apply half the amount of fertilizer for flowering houseplants and one-fourth the amount for foliage houseplants. Too much fertilizer results in plants that become leggy and weak.
 
Location is another factor that should be considered this time of year. Since day length is so short, houseplants may be helped by being moved to areas of the room that receive more light, such as a south-or east-facing window.
 
Avoid placing plants where drafts from doors or direct output from heating ducts may contact them. Relative humidity also tends to be low during the winter. If you do not have a humidifier, frequent misting of the plants or placing them on water-filled trays of pebbles can help raise the humidity. (Ward Upham)

Draining Hoses and Irrigation Lines

Picture
Hoses and shallow irrigation lines may be damaged over the winter if water is not drained. If there is a main shut-off valve for the system, close it and then run through the zones to make sure any pressure has a chance to bleed off. Lawn irrigation systems usually have shallow lines. Though some lines may be self-draining, check to be sure there are no manual drains. If manual drains are present, they should be opened. Be sure to map them so they can be closed next spring before the system is pressurized. If there are no manual drains the system should be blown out with an air compressor.  Lawn irrigation companies often offer this service.
 
Drain hoses by stretching them out and coiling them for storage. Water will drain as you pull the hose toward you for coiling. Store in a protected place. UV light can make hoses brittle over time. (Ward Upham)

Keep Compost Pile Moist

Picture
This is the time of year when there are lots of materials available to compost. Remember that the compost needs to be kept moist so that the bacteria and fungi can break down the raw materials. Use a sprinkler to soak through the pile to the center. Allow the pile to drain. The goal is for the pile to remain moist; not waterlogged. Edges will dry out the quickest and may need a light sprinkling from time to time.
 
If you are interested in composting but don’t know how it is done, see our video at http://tinyurl.com/jn6yppo and/or our publication at http://hnr.k-state.edu/doc/hort-tips/Composting.pdf (Ward Upham)

Roasting Pumpkin Seeds

Picture
Now that Halloween is past, you may be wondering what to do with the pumpkins that were used to decorate for the holiday. Consider roasting the seeds before freezing temperatures destroys the pumpkin fruit. Cut open the pumpkin and remove the seeds and stringy material. Seeds should be washed and dried and the “strings” discarded. Toss the seeds with a little oil before roasting.
 
Flavor can be enhanced by adding a sprinkling of salt to the oiled seeds. Seeds can then be spread on a cookie sheet and roasted for about 25 minutes at 325 degrees F. Times may vary depending on the size and moisture content of the seed. Seeds are done when they turn a golden brown. If seeds are not eaten immediately, store in a zip closure bag in the refrigerator. (Ward Upham)

Water Landscape Plants

It is important that perennial plants go into the winter with moist soil. Even with recent rains, some areas of Kansas have been dry this fall with some portions of the state being under drought conditions for much longer. Watering now is important if soils are dry to help alleviate moisture stress and lessen the likelihood of winter damage.

Although all perennial plants benefit from moist soils before winter, it is especially important for newly planted trees and shrubs due to limited root systems. Even trees and shrubs planted within the last 2 to 3 years are more sensitive to drought than a well-established plant. Evergreens are also more at risk because moisture is lost from the foliage.

A good, deep watering with moisture reaching at least a foot down into the soil is much better than several light sprinklings that just wet the top portions of the soil. A deep watering will help ensure that the majority of roots have access to water. Roots that actually absorb water are killed when the soil temperature reaches 28 degrees F. Those near the surface do not last long in our Kansas winters. We must rely on roots that are deeper, and provide moisture for them to absorb.

Regardless of the watering method used, soil should be wet at least 12 inches deep. Use a metal rod, wooden dowel, electric fence post or something similar to check depth. Dry soil is much harder to push through than wet. 

Trees or shrubs planted within the last year can be watered inexpensively with a 5-gallon bucket. Drill a small hole (1/8") in the side of the bucket near the bottom. Fill the bucket and let the water dribble out slowly next to the tree. Refill the bucket once, and you have applied 10 gallons. Very large transplanted trees and trees that were transplanted two to three years ago will require more water.

A perforated soaker hose is a good way to water a newly established bed or foundation plantings. However, soaker hoses are notorious for non-uniform watering. In other words, you often receive too much water from one part of the hose and not enough from another. Hooking both the beginning and the end of the soaker hose to a Y-adapter helps equalize the pressure and therefore provide a more uniform watering. The specific parts you need are shown in the photo above and include the soaker hose, Y-adapter and female to female connector. It is also helpful if the Y-adapter has shut off valves so the volume of flow can be controlled. Too high a flow rate can allow water to run off rather than soak in.

On larger trees, the soaker hose can circle the trunk at a distance within the dripline of the tree but at least ½ the distance to the dripline. The dripline of the tree is outermost reach of the branches. On smaller trees, you may circle the tree several times so that only soil which has tree roots will be watered.

If using a soaker hose, note the time watering was started. Check frequently to determine the amount of time it takes for water to reach 12 inches. From then on, you can water “by the clock.” Use a kitchen oven timer so you remember to move the hose or shut off the faucet.

​If you are seeing surface runoff, reduce the flow, or build a berm with at least a 4-foot diameter around the base of the tree to allow the water to percolate down through the soil, instead of spreading out. (Ward Upham)

Compost Pile Maintenance

Compost piles should be turned about once per month even during the winter months. This will insure the composting process continues and that all materials are equally composted. A compost pile is “turned’ when uncomposted material is moved from the sides and tops of the pile to the center where it provides “fuel” for the microorganisms that break it down.

This can be done by adding a 2- to 4- inch layer of organic matter to the surface of the soil and tilling or spading in as deeply as possible. (Ward Upham)

Storing Power Equipment for the Winter

Late fall or early winter is a good time to service power equipment such as mowers, tillers and garden tractors. Run the equipment out of gas or treat the existing gas with a stabilizer as untreated gas can deteriorate over time. If using a stabilizer, run the engine long enough for untreated gas in the carburetor bowl to be burned and replaced. This is also a good time to replace the oil (and filter, if present) since the engine is warm. Check and replace the spark plug if necessary.

Some gardeners will also apply a light, sprayable oil into the cylinder through the spark plug hole. Check and clean air filters and replace if necessary. Many mowers and tillers will have a foam prefilter that can become filthy with use. If allowed to become too dirty, engines will run poorly or may not run at all. Sharpen blades, clean tines, tighten screws, replace broken parts and do all the other things needed to keep equipment in good shape. Though such maintenance takes some time and effort, it pays for itself by reducing frustration and lost time due to poorly performing equipment during a hectic spring. (Ward Upham)
