Hazelnut tree irrigation

Find information on when to water hazelnut trees and what type of devices can help manage irrigation.

Water stress to the trees should be avoided from flowering to nut maturity. It is necessary to irrigate often in the summer (especially July and August) as upper soil layers dry quicker than deeper soil layers. Drip irrigation may be optimal while trees are young.

Soil moisture devices such as tensiometers or capacitance probes should be used to determinate when to water, and how much water to apply.
