In What Order Should I Do These 4 Things?

Question

Renovate Weed and Feed Pre-emergent Seed

Answer 1

If you are renovating your lawn, do that first, then seed. Once the grass has grown in, you can use a weed and feed product. Do not use a pre-emergent when seeding, it will interfere with the new grass sprouting. You can use it in the fall.
