Weed Control in the Memphis Area
More than most cities in the U.S., Memphis and the Mid-South’s main lawn management problem is weed control. Our fertile climates and rich soils are the perfect home for weeds to grow and fester. Our mantra from day one has always been to know more about the physiology of weed systems than any other company in the Mid-South, and most importantly, know more about how to kill them. Our lawn care experts are the best at lawn weed control in Memphis.
Types of Weeds
Identifying weeds can be difficult. One must consider several items: the maturity of the weed, the place it is found, and the time of year it emerges. Throughout the Memphis area there are three types of weeds: broadleaf weeds, grassy weeds, and sedges. A homeowner’s choice for the best weed control in Memphis, including appropriate herbicides, is dependent on the type of weed you have in your yard. Our weed control in Memphis offers you superior service and advice when it comes to getting rid of weeds.
Broadleaf weeds are easiest to identify. Like dandelions and clover, they are distinctive from and not botanically related to grasses and sedges. As the name indicates, broadleaf weeds have leaves that are broad and are generally produced in pairs or multiples. The leaves of these weeds are detached from the main stem by a sub-stem or petiole. Their leaves may be simple with one leaflet, like a dandelion, or they may be compound having more than one leaflet, like clover. Veins within the leaf of the weed give a netted appearance in most cases.
Grassy weeds, like crabgrass, are botanically related to lawn grasses. They have a similar appearance and development to that of lawn grass. The leaves of grassy weeds are not detached from the main stem but are narrow with a blade-like appearance. The leaves are produced one at a time in two vertical rows with veins within leaves that run parallel. The stems of these grassy weeds are usually round or flat. Since grassy weeds are often difficult to control once they establish themselves in your lawn, they are generally best controlled with preventive or pre-emergence herbicides. Pre-emergence herbicides need to be applied before germination, as they act by preventing establishment.
Sedges, like nutsedge, have leaves that are similar in appearance and are often mistaken for grasses. Since herbicides used to control grassy weeds are generally not effective on sedges, it is important to distinguish between the two. Sedges have two key identifying characteristics: their leaves are arranged in three vertical rows and they have a triangular stem. Stems of grasses are commonly round or flat with leaves in two vertical rows.
Life Cycles of Weeds
Each type of weed may have one of three basic life cycles of a weed: summer annual, winter annual, or perennial. These three different life cycles of weeds determine when the weeds will produce seeds, grow, and die. These factors help our lawn care experts determine the best plan of action for our weed control.
Weeds that are considered summer annuals complete a life cycle within 12 months. Summer annuals usually germinate in the spring, grow or develop during the summer, produce seeds, and die by the fall or after the first killing frost.
Winter annuals complete a life cycle in 12 months but generally overlap two calendar years. They germinate in late summer to early fall and then begin to develop. They remain dormant or semi-dormant throughout the winter, they flower the following spring then mature and die in late spring or early summer. Weeds that are considered summer and winter annuals reproduce and spread by prolific seed production, becoming a ready source of infestation and establishment when conditions are favorable.
Perennial weeds live for more than two years and may regenerate indefinitely. A simple perennial weed, like a dandelion, may germinate from seed but produces a tap root that, when severed, can produce a new plant. A complex perennial weed can spread by seed as well as creeping above or below ground vegetative structures capable of bringing forth a new plant. Perennial weeds are often the most difficult to control mainly because they are an established plant that has already produced considerable vegetative reproductive structures. Repeated control measures then become necessary in order to get rid of these weeds. Removing the above-ground shoot growth does little toward long-term weed control. Herbicide treatments that act on the above and below ground structures are required for long-term weed control.
