Throw the kitchen sink at weeds

By Gregg Eyestone

My goal of keeping weeds under control this season is reaching a breaking point. The garden isn’t on a public garden tour, but a conscious effort is being made to keep up.

Several tactics have been carried out. None of them have been a complete success.

Growing healthy desirable plants is the first goal. Best watering and fertilizer practices have been applied to the best of my time and ability. The use of mulch is necessary where practical.

Last June, buffalo grass was planted in a portion of the landscape. It filled in fairly well, but there are some bare areas where weeds can grow. I applied a pre-emergent herbicide this first spring.

But there are still some weeds appearing.

Mulch and pre-emergent herbicide was applied to the flower and shrub beds. Products with trifluralin as the active ingredient are most commonly available. It doesn’t control ragweed, which is one of my weed challenges. Pre-emergent herbicides need to be applied when no weeds are present. It can be applied right after removing any existing weeds.

Buffalo grass and most other lawn grasses can be sprayed with post emergent herbicides to manage weeds when necessary. Products containing quinclorac will take out growing crabgrass, foxtail and other undesirable grasses from lawn grasses. It is often blended in with broadleaf weed herbicides.

Crabgrass that sprouts in my pre-emergent treated areas needs attention. Disturbance to the soil surface after activation may result in erratic weed control. Hoeing will likely cause disturbance. Hand weeding is an other option. A product containing sethoxydim may be used according to label directions in shrub, flower and some vegetable areas.

Read and follow label directions on any product you choose to use. Weeds are constantly trying to grow and do their thing. It takes a concerted effort to keep a balance in the landscape.
