Lawn Weed Control

Crabgrass preventer




Contrary to popular belief, pre-emergent weed killers don't destroy weeds and their seeds. They simply stop them from growing. Some seeds are known to last fifty years, so if the herbicide isn't applied each year, the weed will grow.

A quick application of a preemergent herbicide product and all those pesky weeds will lay dormant another year. Yes, dormant. See a preemergent weed control product isn't a pre emergent weed killer. It keeps the weeds from growing which is why it's necessary for you to put down a pre emergent herbicide product every year. 


Hard to Control Weeds in Maryland


Oxalis:Several preemergence crabgrass herbicides have activity on yellow woodsorrel. Unfortunately, a higher concentration of herbicide is necessary for woodsorrel suppression.  Repeat applications of carfentrazone may be effective over the course of a season.


Wild violet: is consider one of the most difficult-to-control broadleaf weeds. It's aggressive growth habit and dense, fibrous root system help it to recover from herbicide damage. We apply 2 applications of Triclopyr, 14-30 days apart.


Nutsedge: looks like grass, but their stems are triangular and leaves are arranged in threes from the base of the plant (grass leaves are in twos along a round stem). They prefer poorly drained, rich soil and thrive in frequently watered lawns. In summer, they grow faster than the lawn and quickly stand above it. Very difficult to control. We apply 2 applications of Halosulfuron, 14-30 days apart. 


Bermuda grass Suppression


DESCRIPTION
Bermudagrass is a low growing perennial grass that spreads by rhizomes (root type stems),
stolons (stems that root), and seeds. The seed head resembles a hand with three to seven“fingers” or spikelets, which are about one to two inches long. Bermudagrass is sometimes confused with annual crabgrass. Bermuda has deeper, rhizome type roots, where crabgrass has a shallow,
fibrous root system with no rhizomes or stolons. The leaves on Bermudagrass are also in a
herringbone pattern. Bermudagrass’s aggressive behavior makes it a tenacious weed throughout the landscape. It propagates both vegetatively and by seed, so it spreads quite easily from one lawn or area to another. Bermudagrass grows in full sun, and does not do well in shade.

 Treatment Program:
We will reduce the amount of bermudagrass in your lawn by greater than 95% Our treatment program most reapply every two to three weeks throughout the season and continue more than one growing season if necessary.
The product applied is a combination of two specialty herbicides. The treatment consists of four applications. These applications need to be applied when the bermudagrass is actively growing, in our area this usually occurs between late May and early September.

 Common Broadleaf Weeds in Maryland


CHICKWEED: germinates during the fall, grows during the winter, produces seed and then dies by early summer. Eco-Lawn can control this weed with a pre-emergent weed control applied in early spring.

CLOVER: is a perennial broadleaf weed that sprouts in the fall. Established patches can be controlled with a post-emergent weed control. May be applied any time during the active growing season.

DANDELIONS:flowers from early spring through summer. Established plants can be controlled with a post-emergent weed control applied any time during the growing season.

GROUND IVY:spreads quickly. It's rapid growth will quickly choke-out desirable grass plants. We can control it with a spot treatment any time during the season.

HENBIT: sprouts in the fall, grows through the winter and early spring. We can controlled it with a spot treatment any time during the season.


WILD ONION:a perennial weed that grows during the cooler months. Can be controlled with a post-emergence spray applied on a warm winter day. Wild Onions and Wild Garlic may require repeated treatments.
