The label of Ferti-Lome Weed-Out Plus Lawn Fertilizer 25-0-4 advises not to apply to newly seeded lawns therefore you would need to wait until the new grass seed has established after 30 days or after the 2nd mowing (whichever comes first) or wait 2 weeks after the application to apply Ferti-Lome Weed-Out Plus Lawn Fertilizer 25-0-4.
