Hello, Stamford, CT. I had a new lawn installed (killed out, top dressed, then seeded) last fall (actually the process was done 3 times..long story)... lots of bad weather right after seeding each time. Finally ended up with green grass, but VERY patchy. After talking to the lesco dealer, I decided to use Siduron and grass seed again this spring, which I did as soon as the forsythia bloomed about 2 weeks ago. Watering alot, but seeds are still sitting on surface - I don't think its warm enough yet. Anyhow - I am noticing alot of what I think is chickweed, and a fair amount of dandelions... I just read the siduron fact sheets and it says it doesn't control chickweed or dandelions. Original Plan WAS: Forsythia Bloom - Siduron and Seed +3-4 weeks - Siduron again +3-4 weeks - Dimension (assuming grass seed is established) and Grub Control Late August - Seed Late Fall - Winterize (21-3-21 Fertilizer + Iron?) Questions... pics attached: 1. Am I correct - Is that really chickweed? 2. Should I worry about the chickweed? 3. Is there a product I can use to control the chickweed and dandelions after I already put the siduron down without worrying about the grass seed I put down? 4. Pic of lawn from 2 weeks ago, and one from this weekend attached - seems like its filling in ok, but grass seed is still sitting on surface, no sprouts - I think soil is too firmly packed. Should I rent a power seeder and try again now, or just wait until fall and aerate, powerseed, etc... Thanks in advance for any thoughts or advice.
