Preparation - Amend soil if necessary. Water doesn't easily penetrate clay soil and passes through sandy soil too quickly.
Weeds compete for water.
When possible, move pots to shady areas. Less frequent, but thorough watering, develops strong root systems and provides greater tolerance to dry periods. To avoid wasting water, turn off sprinklers and hoses as soon as watering is completed. After a month, a deep watering every other week is often adequate. And in a year or so, plants generally thrive with minimal watering.
