Cover Crops Serve Dual Purpose

Gardeners have long used certain plants known as cover crops to help keep soil from blowing away during winter. An added benefit of raising cover crops is that their foliage and root growth can be tilled under in late winter to help loosen heavy soils and improve overall soil structure and fertility. Cover crops generally are sown in late summer or early fall, after summer vegetables are harvested. The type of plant you grow will…Read more about Cover Crops Serve Dual Purpose[Read More]

Consider Garden Mums for Fall Color

While many of summer’s perennials are winding down for autumn, you can refresh your garden’s color with garden mums. Colors ranges from many shades of yellow, orange, red, purple, bronze, pink and white. The flowers themselves come in many different forms, from spider types with long, narrow petals to cushion types that have wider, more compact flowers.

Q: For the last three years, my husband and I have had a problem with our zucchini plants. After one or two pickings, the plants are plagued with a gray-brown bug that looks like a stink bug. Soon, the plant dies. We have put Sevin on the plant as soon as we see the insects, but the plant still dies. We destroy the plant correctly and put diazinon in the ground to prevent further infestation but…Read more about September 1996[Read More]

Layering Gives Old Plants New Life

Many a gardener has noticed that branches of some plants seem to take root and form new plants where they lay on the ground. This is a natural process known as layering. We can take advantage of layering to increase the number of plants in our collection or to share our prized plants with friends and family. The concept is similar to propagating by cuttings except, in the case of layering, new plants remain connected…Read more about Layering Gives Old Plants New Life[Read More]

August 1996

Q. We would like to establish tiger lilies along a 50-foot portion of a bank on a farm pond where grass and weeds now grow. We have lilies growing wild along our field.

A. I think you may mean daylilies instead of tiger lilies, since…Read more about August 1996[Read More]

Much to the dismay of homeowners, landscape trees sometimes grow roots above the surface of the lawn. These roots can be quite a nuisance to lawn mowers and running feet. There are several reasons why the roots come to the surface. Some tree species seem to be more prone to surface roots than others, most notably silver maple, poplar and willow. Sometimes roots become visible due to erosion of the surface soil. But almost any…Read more about Some Tree Roots Surface on Lawns[Read More]
