- Hand watering: fine for small plots. Water the base, not the leaves — wet foliage spreads disease in humid weather.
- Soaker hose: laid in beds, it waters slowly and evenly.
- Drip irrigation: the most efficient for bigger gardens; wastes little water.
- Homemade: pierced bottles or buried clay pots seep water at the roots.
Use harvested rainwater and add mulch.
