| Basin irrigation of fruit trees |
Irrigate. If your fruit trees are being irrigated by drip or bubbler with a basin around the tree it will be critical to make sure they are getting watered regularly. We are usually irrigating three times a week when temperatures break 110°F or if it has been unusually windy.
This just doesn’t mean you’re irrigation clock is set correctly but that you also make sure that drip emitters or bubblers are not plugged. Most emitters and bubblers can be cleaned. Turn on your irrigation system and walk your irrigation lines looking for diminished flow rates or possible plugging.

Under our desert environment, the soil surrounding your fruit trees irrigated by a basin or drip will be totally dry. These dry soils surrounding your plants “pull” water away from your trees and in competition with them. But surface mulches help reduce this problem.
If your fruit trees miss an irrigation, expect to see leaf yellowing and leaf drop the week or two after the water shortage. This can be very dangerous to fruit trees. Leaf drop opens the canopy for intense sunlight and sunburn on the fruit and limbs. If limbs are sunburned this makes them very prone for borer attacks.
This is the worst time of the year to miss an irrigation or cut back on your watering.
