Dormant sprays need to be applied only once during these three months, except for Peaches and Nectarines.
SPRAY WHEN THERE IS NO CHANCE OF RAIN FOR 24 HOURS AFTER SPRAYING. THIS DRY PERIOD HELPS TO MAXIMIZE THE SPRAYS’ DISEASE AND INSECT CONTROL.
For more detailed information such as pruning, fertilizing, growing season sprays, and special tips, please consult our individual Fruit Tree Care Guides available online or in the Nursery.
