Growing Corn in NJ
I live in Houston, a totally different climate, but I'm sure growing there is not different than growing here, only you plant later. I sold my house so I garden on my patio, but this is how I used to do it. Plant when the soil is warm, but don't wait too long. Plant on a raised bed, two feet wide, two rows to the bed, you'll need at least two rows side by side for good pollination. The bed protects against excess rainfall, we got ten inches here Tuesday in 12 hours. Work some 10-10-10 fertilizer in before planting, corn is a heavy feeder and needs proper fertilization. Plant seeds one inch deep, every 2-3 inches, and thin to one every 12 inches. When it is about knee high, or just beginning to tassel, hit it with a nitrogen fertilizer, something like 20-0-0, nitrogen being the first number . Always water after fertilizing. Use a hoe to keep the soil loose during growing, and keep the weeds down. You can plant more corn every two weeks for a sustained harvest. Any questions on any veggies ask, I had a pretty good garden going, I still grow tomatoes, green beans, potatoes, and peppers on my patio and will add onions this fall. Also, rotate your crops every season, keep a journal, as memory can be fuzzy.
