Put evergreen 4 in 1 on new lawn. Is it going to kill my grass?

Question

My nephew and I are both getting our gardens in order. I seeded my grass about 2 weeks ago and its growing very very well. Nephew contacted me and said he was finding a deal on evergreen 4 in 1 weed and feed in the co-op. Asked if I wanted it too. I said sure. I just finished spreading it when a neighbour told me it’s not meant for gardens under 8 months old and not for new lawns. What can I expect from it? Is it going to kill my grass? Or am I panicking over nothing? Any counter measures I can take?

Answer 1

A general rule of thumb is to wait at least until you have mowed the new grass four times before using any standard postemergent broadleaf herbicide. A standard pre-emergent herbicide should not be applied until at least three to four months after seeding the area.
