How to Prevent Crabgrass in Bermuda Grass Lawns


If you are looking for a hardy and durable grass to plant in your lawn, try Bermuda. As with most grasses, Bermuda grass can be plagued with crabgrass. This is especially true if the grass has not been maintained. Though Bermuda grass grows dense and is quite drought and heat tolerant, it, too, can be infested with crabgrass. The best cure for ridding your Bermuda lawn of crabgrass is to deal with the problem before it starts. With a little time and attention, your lawn should be lush and weed free.

Step 1

Grow your Bermuda grass in full sunshine. Bermuda grass will not tolerate growing in conditions that are shady. Bare spots will form and crabgrass will set up house there.

Step 2

Mow your Bermuda grass at the proper height and do no scalp it to open the lawn up to bare spots. Keep the grass at a height of one to 1 1/2 inch. This will keep the grass healthy and reduce the chance of crabgrass setting in.

Step 3

Water the Bermuda lawn regularly and deeply. Depending on the temperatures in your area, water the grass at least once or twice a week. Set a used aluminum can such as a used tuna fish can into the middle of the lawn. When the water has filled the can, the Bermuda grass has been watered enough.

Step 4

Apply a crabgrass preventer to the lawn in early fall and once again in February. This will help prevent any seeds that might be lying dormant in the lawn from germinating.

Step 5

Fertilize the Bermuda grass three times per year. Use a fertilizer that is high in nitrogen applied in the spring and late summer. Use a winterizing fertilizer in late fall to protect the grass from injury during winter.
