- Delete daily irrigation when planting in winter. Irrigation frequency can be reduced slightly (e.g. 2-3 times each week instead of every other day) when planting hardened-off, field-grown trees that were root-pruned during production. Establishment takes 3 (hardiness zones 10-11) to 4 (hardiness zones 8-9) months per inch trunk caliper.
- Irrigation frequency can be reduced slightly (e.g. to once or twice each week) when planting hardened-off, field grown trees that were root-pruned during production.
- At each irrigation, apply 2-3 gallons per inch trunk caliper to the root ball. Apply it in a manner so all water soaks into the root ball. Do not water if root ball is wet/saturated on the irrigation day.
- Trees take much longer to establish than 3-4 months per inch trunk caliper. Irrigate in drought the following summer.
