Planting & stewardship

1
Verify both the named cultivar and rootstock on the nursery tag before planting.
2
Whitewash newly exposed bark and protect cold-sensitive trees during hard freezes.
3
Feed in several light applications during the active season rather than one heavy dose.
4
Let fruit color and flavor—not a calendar date alone—confirm harvest readiness.
