weed grass seed head identification

 Preemergents are an added ingredient in many spring fertilizer. The bags will be labeled “with Crabgrass Control” or “Crabgrass Preventer”, etc. Make sure you spread the fertilizer at the correct nitrogen (N) level for your grass type. For help developing a sound fertilizer program, read the page on Developing a Fertilizer Program.

Learn From the Mistakes of Others: Spraying your lawn with a a non-selective herbicide such as Round-up, etc is not an effective crabgrass control. It doesn’t harm the seeds in the soil. Although it will kill all the grass and weeds it touches, the following year you will still have the problem with crabgrass and other broadleaf and grassy weeds that start from seed.

Cultural Practices that Help Prevent Grassy Weeds

It develops from a fibrous root system and has a prostrate to upright growth habit. With mature plants, it is common to see the stems branching out at the base, remain prostrate for an inch or two and then curve upward at a 30 to 70 degree angle. Each plant can produce multiple stems that can easily grow twice the height of the leaves.

For Established Weeds

Cultural Practices

An essential part of identifying grassy weeds has to do with their life cycles. For example, you may be able to hand-pull a few annual weeds to enjoy a weed-free backyard cookout, but perennial grassy weeds have a deeper root structure that can give rise to new weeds—even if you no longer see the weeds in your lawn. Learn what the different life cycles of lawn weeds mean for your control plan.
