When To Apply Weed Whacker
It is best to apply weed whacker when the weeds are actively growing and young, but may be used all year long. The directions restrict usage to two times a year in the same area. Wait 3-4 weeks after using Weed Whacker before overseeding.
Do not around and in dichondra. Don't use Weed Whacker around desirable vegetation and avoid drift from winds. Do not use on newly seeded turf; however, you can use it after the third mowing. If temperatures exceed 90°F., do not apply.
Before applying this three-way herbicide, water lawn thoroughly. Wait for 48 hours after application to water.
- Cool Season Grasses (Such as Fescue, Rye, and Bluegrass)
- Use 8-13 oz in 6 gallons of water to cover 2,500 sq. Ft of lawn area to kill such weeds as wild onion, dandelion, pennywort, and similar weeds. If you have a smaller area, use three tsp in 2 qt of water applied to 100 sq ft.
- For hard to control weeds like Dock, Thistle, Ragweed, and Bindweed, use eight oz in 6 gallons of water (or 3 tsp in 2 qt of water), and apply directly to plants, wetting them thoroughly.
- For Poison ivy, and Poison oak, use 2 oz in 1 qt of water and drench these plants when they have full leaves. Repeat in 4 weeks if needed. These weeds may require a fall application.
- Warm Season Grasses On st. Augustine, Bahia, common Bermuda, Centipede, Zoysia, and Bent:
- Use a one-half rate which is 4 to 6-1/2 oz in 6 gal of water to treat 2500 sq ft (3 tsp in 4 qt of water applied to 200 sq ft). Make two applications 30 days apart.
- Do not spray grasses if stressed from heat, drought, etc. Slight turf-yellowing may occur, but should disappear after about 1 week.
