Sufficient watering is a critical factor for maintaining your plants for the first 12-18 months.
Supplemental water is absolutely necessary during Spring and Summer or during dry weather at any time. Particularly important is the period in late winter and early spring when plants must have sufficient water for new growth to begin.
A slow deep watering is essential, rather than several quick applications. Water once a week, (normally 30 minutes to one hour per tree), in hot weather, unless there is at least one inch of rainfall each week to 10 days. You may want to check the soil moisture about one foot down (at outside of the hole to avoid root damage) to make sure you are watering enough, but not too much.
