Lawn Weed Control & Prevention
How to Save My Lawn from Weeds
Do you have visions of a beautiful lawn surrounding your home without all of the weeds? Have you tried everything, but your lawn is still being taken over by crabgrass, dandelions and god-knows-what else? Green Giant’s weed control and prevention services can help!
Every year we see all kinds of lawns with extreme weed problems. We know what needs to be done to wipe out weeds and make your lawn something you can be proud of. The more severe your problems, the more dramatic the change will be!
When it comes to killing and preventing weeds, there are three different categories to consider – and each has to be treated differently.
What Kind of Weeds are in my Lawn?
- Broadleaf Weeds – There are dozens of different types of broadleaf weeds that infest lawns in our area. A few examples include dandelion, clover, oxalis, ground ivy and wild violet. These are perennial weeds – meaning they live year round.
- Annual Grass Weeds – The #1 lawn weed in Pennsylvania is an annual weed – crabgrass. Other annual grasses we deal with are Goosegrass, Foxtail, and Barnyard Grass. Annual plants only live for one growing season. The plants will grow from seeds in the spring, mature and produce seeds during the growing season and, in the fall, they will drop their seeds and the plant will die. The next spring, the process starts all over again.
- Sedges – There is only one type of sedge that is considered a lawn weed in southeastern Pennsylvania – but it’s a doozy! It is called Yellow Nutsedge. While it appears to be a fast-growing, oversized, yellowish-green grass, it’s not actually a grass (or a broadleaf weed).
How to Keep Weeds out of My Lawn?
Broadleaf Weeds are most often controlled by a liquid weed-killer while they are actively growing. This is a ‘foliar treatment’. The foliage (leaf) of the weed is lightly sprayed and the herbicide is absorbed into the plant and moves down into the root system to kill the weed.
Crabgrass and other Annual Grassy Weeds are not controllable with the same herbicides that kill broadleaf weeds. And, since it is very likely that a lawn will have both dandelions & crabgrass, different treatment materials are needed at different times of the season.
The best way to control crabgrass is with two Crabgrass Preventer treatments. A crabgrass preventer will kill the seedling when it begins to grow. These treatments are typically done in early spring and the other in late-spring or early summer.
Sedges – Because a sedge is biologically different than the other weed types, it needs to be treated with a specialty product that will control the Nutsedge without damaging your good turf-type grass. As odd as it seems, this material will not kill your broadleaf weeds or your crabgrass. The material is sprayed onto the blades of the Nutsedge while it is actively growing. It is important to treat the nutsedge before its seeds fully mature and create more problems in the next year. The seeds grow on the top of the plant.
After being treated, it can take up to two weeks for the nutsedge to start turning brown but, once the nutsedge is sprayed, it will stop growing which makes it much less unsightly.
The weed control methods above can do a good job of getting rid of weeds but, it is also important to keep your grass healthy and thick to make it harder for the weeds to compete.
Lawn Fertilization is the cornerstone of a turf-management program. A well designed fertilizer program will provide the right types of fertilizer at the right time of year and in the right amounts to help the density of your lawn.
Mowing is also a very important part of maintaining a nice lawn. We do not provide mowing services but, we know a lot about it. Learn more about proper mowing.
