Got Questions?

Frequently Asked.

Everything you need to know before you start your daily routine.

Can I use pre-emergent fertilizer if I plan to seed my lawn?

No. Pre-emergent lawn fertilizer will prevent all seeds from germinating, including grass seed. If you plan to overseed, wait at least 6–8 weeks after applying a pre-emergent before seeding.

How does pre-emergent fertilizer work?

Pre-emergents create a barrier in the soil that stops weed seeds from sprouting. However, they do not kill existing weeds—so they must be applied before weed seeds germinate to be effective.

When should I apply pre-emergent fertilizer?

Apply a spring pre-emergent fertilizer before soil temperatures reach 55°F for three consecutive days. This is the point at which crabgrass and other weeds start to germinate. In most areas, this falls between late winter and early spring.

Should I apply fertilizer or pre-emergent first?

If you use a fertilizer and pre-emergent combo, you can apply both at the same time. Otherwise, apply pre-emergent first to block weeds, then fertilize 2–3 weeks later to encourage healthy lawn growth.

Do I need to water in pre-emergent fertilizer?

Yes! To activate the pre-emergent barrier, water the product in with at least ½ inch of irrigation or rainfall within 48 hours of application.
