I have 3 houses that I ABSOLUTELY have to have greener than Augusta National Golf Course. I have started them on 28-8-8. I applied as directed. I am going to wait 3 weeks and apply the same 28-8-8 but 3/4 the amount. I will wait 6 weeks and apply 16-8-10. Will this suffice? Is there ANYTHING else I can do to bring this already decent lawn into a turbo charged green machine??? Thanks in advance!
