If you only have a balcony, patio, or postage-stamp yard, choosing the best crops for large harvests on balconies can transform a tiny growing space into a remarkably productive kitchen garden. A handful of carefully selected vegetables and salad crops can produce weeks, sometimes months, of harvests from a few containers, particularly in temperate zones where spring and summer offer long growing windows.
The secret is not cramming in more plants, but choosing the right ones. High-yield crops such as cut-and-come-again greens, climbing beans, and compact tomatoes will outproduce sprawling vegetables many times over, giving you bowls of food from very little soil.
