I've never been able to raise corn. It would get knee high and then bloom. Never form ears. I found Silver Queen starts at the Home Depot, and very carefully planted them 6-8 inches apart, hilled them when they got hip high, fertilized them frequently- they are now waist high and in bloom. What am I doing wrong? I live in zone 10/11, with sand- but I amend the corn bed with garden soil and fertilize and mulch like crazy. Is it the heat? Any ideas??
