Weeds are tough little fighters. That’s what allows them to grow in so many different environments, including full shade, full sun, and even in the cracks between sidewalk slabs. Unfortunately, most types of grass are not nearly as hardy as the weeds they fight for resources.

Getting your grass to be green, thick, and healthy is the first and most important step in a strong weed control plan. A lush lawn will shade weed seeds and prevent them from getting the sunlight and water they need to germinate. So no matter what is going on with your weed situation, it’s important to stay on top of your watering, trimming, and fertilizing schedule.

Don’t Forget to Aerate Your Zoysia Turf

When your soil becomes compacted, your grass plants need you to perform core aeration. The weeds do a fine job of growing down into hard soil, but grass does not. Aeration allows more water and nutrients to get down to the Zoysia roots, and that promotes thicker, healthier turf that can fight off more weeds.

In particular, broadleaf weed killers are commonly misused. When people don’t see results in 24 hours, they tend to re-apply the product. Putting too much of these chemicals on your lawn is a common cause of turf damage. This is why hiring a lawn care professional to handle your weed control strategy is a smart idea.

Our lawn care professionals are dedicated to complete customer satisfaction. We communicate with our clients to make sure they know what treatments we will do, and when we will perform them. Our team can help set up sprinkler timers and give advice about what nutrients your grass is lacking. Seasonal lawn care tasks are a breeze when you let Kemko handle them for you.

The irrigation interval will vary from site to site depending on the environmental conditions at that site and soil type. The general rule to turfgrass irrigation is to water “deeply and infrequently”. Localized dry spots or hot spots can be watered by hand as needed, but only run the irrigation system when the entire lawn is dry. For more information on turfgrass watering, see HGIC 1225, Conservative Turfgrass Irrigation.

If grubs (the white larvae of beetles, such as Japanese beetles) have been a problem in previous years, monitor the grubs by cutting a square foot piece of sod on three sides and peel it back. If more than six grubs are found under the sod piece, apply a lawn insecticide labelled for grub control according to label directions. For more information on white grub management, see HGIC 2156, White Grub Management in Turfgrass.

This turfgrass maintenance calendar may be used on turf growing throughout the state; however, management practices will need to be adjusted based on the year’s climate and the region where the turf is grown.

September through December

During periods of environmental stress, high temperatures, or a lack of rainfall, slightly raise the mowing height until the stress is eliminated. Always mow with a sharp mower blade and use a mulching type mower to leave the clippings to decompose on the lawn. The mower blade will need sharpening on a regular basis, which is usually about once a month. If the bagger is picking up soil, especially sand, the mower blade may need to be sharpened more often than once per month.

Broadleaf weed herbicides can be applied as necessary for control of chickweed, henbit, and other cool-season broadleaf weeds. Selective herbicides can also be applied during winter for control of annual bluegrass and other winter annual grassy weeds. Contact the local County Extension office or the Home & Garden Information Center for weed identification and control measures. See for HGIC 2310, Managing Weeds in Warm Season Lawns for more information.

Irrigation: In the absence of rainfall, continue to water to prevent drought stress. After the lawn has become dormant, water as needed to prevent excessive dehydration. This is especially important if warm, bright days preceed days forecasted to be in the low 20’s or lower.

Late Summer: Depending on the soil type, apply ½ to 1 pound of actual nitrogen per 1,000 square feet before August 15 using a fertilizer that is also high potassium, such as a 15-0-15. It is important for the soil to have sufficient potassium, especially late in the growing season as the grass enters dormancy. Potassium is important for disease resistance and cold weather hardiness.
