How long should I wait after seeding my lawn before applying Jonathan Green lawn Weed Control for broadleaf weeds like dandelions?
The new grass seed should have a chance to establish. It should be mowed at least three times before any broadleaf weed control products are applied to the lawn. This is also true when you’re spreading my Jonathan Green Weed & Feed. However if you have applied my Jonathan Green Crabgrass Control plus Green-Up Lawn Fertilizer, wait four months before seeding your lawn.
