Q.

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

Zone Cork Ireland | EddieoD added on July 9, 2019 | Answered

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?

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.

Contact the manufacturer customer service number on the packaging and directly ask them about this product and your application.
