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.
Propagate new plants from cuttings. Rosemary, lavender, sage. Remove leaves on the bottom of stem. Place cuttings in glass containers with water in a sunny window. In two weeks, there should be roots sprouting. Change the water every four or five days. Add water daily if needed. After roots develop, dip roots in cinnamon or raw honey and plant directly into clean soil. Potting soil if indoors. Gardening soil if outdoors. Organic soil only for plants you eat.
