Growing Corn Intensively July 25, 2013 Sue Martin July 25, 2013 Here are the first ears of corn in my 4 foot square urban corn patch. Read my post at planting time Growing Corn in A Small Garden. Despite my best attempts to shield the corn from marauding birds, I had to replant parts of the patch twice. Finally, I put bird netting over the entire raised bed of corn and zucchini until the plants were two feet tall and able to fend for themselves.
