I am interested in buying a slit seeder. I have done a lot of research and I think the lesco lawn renovator would be the way to go. Up until now I have been a fertilzing company. We now have about 1000 clients and hope to add another 500 this coming year. I think we could sell a lot of people on slit seeding as it will improve their lawn in a hurry - right? I have zero experience with slit seeding and I just wanted to ask a few questions about it: 1. How long does it take to do the average 5000 sq ft lawn? 2. Is it necessary to do 2 passes from different directions? 3. Is 8 # of seed per 1000 good? Could I use less/more? I guess it depends on how sparse the existing grass is? 4. What kind of maintenance do these machines need? 5. What kind of waterng schedule do the seeds need to grow successfully? 6. What else do you put down with the seed? Starter fertilizer? 7. Is 4 to 5 cents per square foot a fair price? Thanks for all your help. If their is anything else I should know, please share your wisdom with us.
