What It Controls

  • Dandelion
  • Clover

The herbicide portion adheres to moist weed leaves and moves systemically through the plant to control weeds at the root.

Why 18-2-3?

This balanced formula supports turf density, helping your lawn compete naturally against future weed pressure.

Application Timing Matters

  • Apply to moist grass (early morning dew works best)
  • Avoid temperatures above 85°F
  • Do not water for 24 hours after application
  • Do not mow 48 hours after application

Proper application improves herbicide uptake and overall effectiveness.

Important Use Notes

  • Do not apply to newly seeded turf until after 2–3 mowings

Frequently Asked Questions

What does Lesco Weed & Feed 18-2-3 do?

It feeds your lawn with an 18-2-3 fertilizer blend while controlling broadleaf weeds like clover, dandelion, chickweed, and plantain.

How long before I see results?

You will typically see weeds curl and begin dying within 3–7 days, with full results in 2–3 weeks. Turf color improves within days of application.

Is it safe for all grass types?

It is safe for Bermuda, fescue, ryegrass, Kentucky bluegrass, zoysia, and most common turf types. Avoid using on St. Augustine (Florida varieties), bentgrass, or dichondra.

How often can I apply it?

Most lawns only need 1–2 applications per season. Wait at least 6–8 weeks between applications.

Can I seed after using Weed & Feed?

No. You must wait 4–6 weeks before overseeding after applying Lesco Weed & Feed.

Can I water after applying?

Do not water for 24 hours. The granules need time to adhere to weed leaves for herbicide absorption.

Is it safe for pets?

Pets can return to the lawn after the product is fully dry. Sweep granules off sidewalks and patios before watering.

Reviews

Applied according to directions. Spread

"Applied according to directions. Spread product over damp grass and did not water for 48 hours. It has been several weeks and there is no change whatsoever to the lawn. All weeds are still present and grass has not gotten any greener. I would not buy this product again."
