A drip irrigation system is a water-efficient solution that helps get moisture right down to the roots. You might expect to pay top dollar for materials and installation of a quality irrigation system, but in reality you don’t need much more than a plastic bottle and a sock. Punch holes in a plastic bottle, drop in an old sock, then bury the bottle to the neck and occasionally fill it with water, which will slowly leak out to the surrounding roots.

Greenhouse
A greenhouse creates the ideal environment for growing plants, but most people don’t have the space to build one in the backyard.
