A weed is any plant growing out of place. By this definition, any plant could be a weed if growing in a location where it is not wanted.
…Annual weeds grow rapidly, flower, set seed and die in a single season. New annual weeds germinate from seeds each year. Before they die, most annual weeds produce large quantities of seeds.
It is very important to destroy these…
Air-drying is the best way to preserve cockscomb. After harvesting cockscomb, strip the foliage from the stems. Tie the stems into small bunches with rubber bands. Hang the loose bunches upside down in a warm, dry, well-…

Yellowjackets are social wasps that build paper nests in the ground, a log, building wall, attic, or other sites. The workers from the colony travel up to a few hundred yards from the nest while looking for food. In early summer, the…
Red raspberries sucker freely. If not confined, plants will spread rapidly. Red raspberries are most productive when grown in 2-foot-wide hedgerows. If the raspberry planting is several feet wide, plant rows need to be…
The forsythia is easily propagated from softwood cuttings. Softwood cuttings should be made from the current season’s growth in late June or early July.
Using a sharp knife, cut off 4 to 6-inch long shoots. Pinch off the leaves on the…
After harvesting the garlic, dry the garlic in a warm, dry, well-ventilated location. Place the garlic on an elevated wire screen or slotted tray to promote drying. When the tops have dried, cut off the dry foliage 1 inch above the…
The frequency of watering may vary considerably from container to container. Watering frequency depends on the size and type of container, composition of the potting mix, plant species, and weather conditions. Some plants, such as…
The rate of decomposition depends upon the composition of the compost pile, level of management, and other factors. A well-managed compost pile (one that is watered and turned regularly) containing a mixture of shredded plant material should be…
Black walnut (Juglans nigra) is a common woodland and landscape tree in the Midwest.
Much has been written about the allelopathic properties of black walnut. When plants produce a chemical that prevents the growth of…
The roots of trees continue to grow until the ground freezes. If the weather is dry, continue to water newly planted trees until the soil freezes in winter. Small trees usually require watering for 1 or 2 growing seasons. It may…
The frequency of aeration is largely determined by the soil type and the amount of use. Lawns growing in heavy, clay soils and those subject to heavy foot or pet traffic should be aerated twice a year. Once a year should be sufficient…
To encourage vigorous growth and abundant bloom, hybrid tea, floribunda, and grandiflora roses should be fertilized two or three times a year. Fertilizer applications can be made in early spring (immediately after pruning), during the first…
Mowing frequency is based on the growth rate of the turfgrass and mowing height. As a general rule, never remove more than one-third of the total leaf surface at any one mowing. Shorter mowing heights require more frequent mowing. A lawn…
Pinch chrysanthemums 2 to 3 times from spring to mid-summer. Remove the stem tips when the shoots are 6 to 8 inches tall. New lateral shoots will develop along the stems. Pinch again when these new shoots reach a length of 6 to…

Most turfgrasses have a difficult time growing in the vicinity of large shade trees. If your efforts to grow turfgrass are unsuccessful, there are alternatives. Areas around and beneath trees can be mulched with wood chips or shredded…
Kentucky bluegrass is an excellent choice. Bluegrass provides good cover, yet is less competitive than other cover crops. Late summer (mid-August to mid-September) is the best time to establish bluegrass by seed. Do not sow…
Blueberry plants should not be allowed to bear fruit in the first 2 years. Any blossoms which form should be removed (rubbed off). Removal of the flowers will maximize vegetative growth and increase yields in later years. …
