I am in the process of cleaning up an existing weedy garden bed. I am converting part of it into lawn, and do fresh planting of roses in the rest. I live in north Indiana. It seems this should be a fairly basic affair but I want to make sure I have the steps right:
1. Remove weeds.
2. Till the soil.
3. I read somewhere that I need to apply something like round-up to kill any weed seeds, wait 2-3 weeks, before doing the subsequent steps. Is this necessary? Would using a pre-emergent like Scott's Turf Builder be better, considering that I want to plant roses in part of the area? How about weed-b-gon?
4. Add some top soil to level out the area.
5. Put in seed, and seed fertilizer.
6. Cover the area with straws.
Is it less complicated to use sod instead of seeds?
FYI: I have a lawn treatment service that does 6 applications a year to keep weeds at bay and ensure health of grass.
Any insights/clarifications will be greatly appreciated.
