Due to the drought last year, I have one client who will need his lawn seeded this spring. We have also agreed that it will be done again in the fall. Since it will be seeded this month I did not apply a pre-emergent and his lawn is full of henbit. I read the label on my Trimes Plus and it says to wait until the 3rd mowing to use. Could I use it 2-3 days prior to seeding? It does not say anything on the label about that (or I missed it). Thanks for the help.
