So you’re short growing space? Pretty much every city gardener can relate. Once you cram in your tomatoes, peppers, onion, beans, peas and cukes, your small plot can begin to look like a veritable vegetable jungle—not a square inch of soil showing. If not careful, your attempts to grow more actually hinder your abilities for your garden to produce, as maturing plants crowd out light needed for others to grow, you can’t find those hidden cucumbers or squash, and vining plants become a tangled mess.
