Plant in blocks, rather than rows.
This creates shade for roots and reduces evaporation.

to avoid evaporation loss and set sprinklers to hit the landscape only, not sidewalks, driveways or walkways.
which compete with vegetables for water.
in spring and fall for better water penetration through the soil.
with similar water needs in the same area for easy irrigation. For example, cucumber, zucchini and squash require similar water applications.

Water when footprints or mower tracks are easily visible.
for broken heads and clogged nozzles, and learn how to manually operate your system so you can shut it off during rainy or cool periods.
Add soil amendments

Set mower blade to the highest level—
2.5 to 3 inches—and make sure it’s sharp. This reduces stress on grass and improves its drought and heat tolerance. Leave grass clippings on the lawn.
Plant drought-tolerant native species
like purple desert four o’clock, orange butterfly milkweed, silver prairie sage and pink swamp milkweed.
