I have 10lbs of all purpose miraclegro and I haven't fertilized the lawn this year. One can really tell because it is growing very slowly. Only grew like 1/2 - 1inch this year and growing season is almost over. I know miraclegro has those gardern feeders but I think that uses 1lb per 500sq ft but that is too much feeding/expensive and you cannot control the amount of feeding. So, does anyone use Ortho Dial N Spray? If so, what quantity do you use and how often? Keep in mind that I have not fertilized this year, how much do you think I should start off with? I prefer liquid because I don't like granluar, I used it before and takes too much time. Also, I was planning to use Weeb b Gon hose end spray on my entire lawn this Friday to get rid of those clovers that caught fire over my lawn. How long should I wait until applying fertilizer? I live in NY, my lawn size is about 4000sqft. Thanks.
