I sowed a 1.5 acre lawn at the begining of June. I fertillized it with 10-10-20 in August, which resulted in a good consistent green lawn. However, now there are large patches of yellowish/light green areas. Should I fertilize it again now, or wait until March/April? If now, what is the best fertilizer to use -10-10-20?
