grassy weed in kansas seed head

HOW TO CONTROL: In garden beds, heavy (2-3 inches) mulch is a good deterrent. It blocks the light from reaching the seeds. But in lawns, herbicides may be your best bet.

Henbit

Fall – Early fall is the best time to kill dandelions with herbicides. In early fall, nutrients are transferred from the leaves down to the roots. Herbicides applied during this time follow the same path down to kill the plant, root and all.

DESCRIPTION: An annual that rarely grows taller than 2 inches along the ground and forms a thick, dense mat that produces small, white flowers.

GROWING CONDITIONS: Dandelion is a perennial that grows best in moist areas in full sun; however, it can survive some shade and dry conditions once established.

Windmill grass is a warm season perennial grass. It greens up in the springtime at the same time as buffalograss. It grows well during the summer, and then it turns brown and goes dormant in the fall like buffalograss. Therefore, it makes it harder to find selective herbicides that can remove windmill grass from a buffalograss stand. Currently, homeowners can remove windmill grass from a buffalograss stand by spraying with a non-selective herbicide such as Roundup or herbicides that contain the active ingredient glyphosate.

Buffalograss – Controlling Windmill Grass

One of the potential drawbacks with buffalograss is that it doesn’t grow quite as dense as other turfgrasses such as tall fescue, Kentucky bluegrass, zoysia grass or Bermuda grass. Therefore, the plants aren’t as close together as the other grasses. And, that leads to more opportunities for weed seeds to germinate in the buffalo grass stand and contaminate the buffalo grass stand with weeds.

NOTE: Tenacity is a herbicide that is now labeled for buffalograss. It was not labeled when this video was made. Tenacity is selective and will not harm the buffalograss but will control windmill grass though it may take two applications. However, Tenacity is not marketed for homeowners but can be purchased through certain online distributors. It is not restricted use.
One of the potential drawbacks with buffalograss is that it doesn’t grow quite as dense as other turfgrasses. That leads to more opportunities for weed seeds to germinate in the buffalograss stand and contaminate the lawn with weeds. This segment shows how to control one of those weeds — windmill grass.

Some common examples of weed problems in buffalograss are tall fescue, Kentucky bluegrass, Bermuda grass, and henbit is a big problem in the spring. What we’re looking at here today is windmill grass.
