Hi, I am starting my own landscaping business next spring and I have a some questions about lawn installation. First of all, is it feasible to rake the ground with a landscape rake for preparation or do I need to use a harley rake or rockhound? Second, I was thinking of broadcast seeding grass seed and then packing it down with a roller. Would that work or should the lawn be hydroseeded or use a slit seeder? Also, do you soil test and spread fertilizer before planting grass seed? What equipment do you other landscapers own/operate. Can you install lawns all season? Also, does anyone lay sod and seed and what percent of your jobs do you lay sod versus plant seed? Thanks for your time and advice.
