DIY? Bucket drip kits, a one time cost of $12, allow growing vegetables during the dry season using drip irrigation. Drip irrigation, originally developed in Israel, targets precious water to where it needs to go, the roots of the plants. Much less labor - it uses water efficiently. Less to lug, less time spent fetching it, more time gardening.
Irrigation spikes - attach these spikes to old soft drink bottles to create an efficient irrigation system for your garden! The slow-drip design delivers water deep into the soil, so your plants stay nourished while you save time watering.
