Healthy lawns that have been fed four or five times a year will be strong enough to survive up to a couple of months with no water.
Feeding your lawn while we are getting spring rain will strengthen the grass and help it to grow new roots. Use a brand you can trust to feed your lawn with a specially controlled, slow feeding that will work gradually over a couple of months. Follow the directions.
Mow your grass taller. By adjusting your mower to a higher setting, you will encourage the lawn grow deeper roots to match the increased blade growth. A taller lawn with deeper roots will be able to find moisture and endure hot, dry weather.
Get rid of crabgrass, dandelions and other aggressive weeds. They steal what little water there is from your grass during dry weeks. The first spring application of weed-and-feed type fertilizer prevents crabgrass. The second application feeds while getting rid of dandelions and other weeds.
If you are able to water your grass, water long enough to get moisture deep into the soil. Lawns need about one inch of water a week. Shallow watering creates shallow roots.
Use a rain gauge to determine how much water you should provide to come up to one inch. That is, if it has rained half an inch during the week, you need to provide the balance, or another half-inch.
