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.
