Keeping your plants alive under watering rules becomes a challenge. Here are some tips to avoid water stress!
1) One or two deep irrigations with the garden hose in spring and early summer before those water restrictions go into place will do wonders at keeping ornamental bushes and trees alive over the summer drought.
2) Fruit and nut trees produce crops best if they receive continuous daily watering during blooming and fruit development phases. However, they too can be kept alive if given generous watering a few weeks apart. Your crop may not be as plentiful but the trees will survive.
3) Vegetable gardens require daily watering immediately after seeding or transplanting as they get established. Vegetables like carrots, beets and other root vegetables do not fare well in restricted water conditions, so limit planting those. Vine vegetables like squash, cucumbers, zucchini and pumpkin can survive on watering twice a week. Consider containers for things like tomatoes and beans if water is restricted.
4) Bermuda grass and Buffalo grass lawns are more drought resistant than other grasses. If you live in an area where watering is restricted, consider planting drought resistant grass varieties. Cut watering to half and water only twice a week even before water restrictions go into place. This will harden your lawn to drought conditions. Some lawn owners have even replaced lawns with decorative stone and drought-friendly plant varieties like cactus and decorative grasses.
