Most broadleaf weeds that invade lawns can be effectively controlled with the use of selective weed control materials that are currently available. These products are referred to as selective because they only affect the weeds and do not harm the grass plants in a lawn. There are, however, some weeds that are extremely difficult to control and some that cannot be controlled with the use of these materials.
Special attention and care is often needed to control these persistent weeds. Some difficult to control weeds found on home lawns are listed below. If weed problems such as these exist on your lawn, your Warner Robins, GA Weed Man can assist you with a program that will help reduce or eliminate this problem over time.

Ground-Ivy or Creeping Charlie
Glechoma hederacea L. This is a perennial weed that has a creeping growth habit. It lays prostrate along the ground with square stems and roots at every node. Its leaves are round with toothed edges. A distinguishing feature of this weed is that its stems and leaves produce a mint like odor when crushed. This weed is more readily controlled than the previous two, however, like most of the weeds mentioned, it will take an ongoing effort by a lawn care professional to control it.
Other Difficult Weeds
Other weeds found on home lawns that are considered difficult to control include field bindweed, wild strawberry, mossy stonecrop, yarrow and knotweed. A combination of proper cultural practices, adequate nutrition and a progressive weed control program that may include repeat applications of government regulated weed control materials will help to control these weeds over time. It may require several years of effort by a lawn care professional and the homeowner before adequate control of these weeds is achieved.

These weeds are seldom a concern in Georgia lawns, however, when they do appear they can present a major problem. All are perennial plants and are extremely persistent. All reproduce by underground stems called rhizomes that make them very difficult to control. They cannot be selectively controlled on a lawn using weed control materials. They can, however, be effectively dug out of a lawn as long as care is given to remove entire plants, including all underground reproductive structures (seeds, rhizomes, roots).
