I am new to slit seeding, so I have few questions. I bought a used Olathe 38 seeder (three point hitch) and a walk behind turf revitalizer. My plan is to spray the lawn with Roundup,wait an mow and vacuum after it dies. Again, spray anything that didn't die the first time. I done a soil test earlier this year and added lime to bring the PH up. I was thinking about broadcast seeding half of the seed and aeravating (First Products aeravator) and then slit seed the lawn with the other half of the seed (TTF) in one direction. Will this leave a row effect by doing it this way? Or would it be best to just aervate and then slit seed in two directions? Then add a starter fertilizer and water. This is a 24,000 sq.ft. lawn. I will seed at a 8 lb. per 1,000 sq.ft. rate. Any suggestions would be apperciated.
