How to control summer weeds
1. Hand-pull large summer weeds
In the heat of summer, hand-pulling weeds is always best.
It removes the majority of weed root systems, limits soil disturbance, reduces reliance on pesticides, and is the only way to remove certain weed species (like nutsedge).
2. Spot treat summer weeds

3. Planting seed in summer
Replace the newly weeded areas with grass.
- You can seed or propagate in warm-season lawns anytime in spring and summer.
- In cool-season lawns, seed in the spring or fall. At the peak of summer, conditions can be challenging for growing grass from seed, and it may need extra water and care.
Sunday Tip:
The best weed prevention is a thick lawn. Overseeding your lawn with better grass seed blends will help get you there.

What do summer weeds tell us?
Weeds are indicators we should pay attention to. Although we’d like to blame the hot and dry weather, consistent weed presence tells us there might be other soil issues like:
If you see weeds year over year, primarily confined to a single area, you may need to fix the underlying problem.
Sunday Tip:
If you have a cool-season lawn and your lawn is covered with weeds, you may have to change your approach to weed control. We recommend you try mowing much lower than usual, followed by overseeding.
