Before you plant

Required microclimatePlacement is part of the growing system.

Zone C — morning shade, hot afternoon sun, at the west end of the sunnier south-facing side. The extra heat finishes the fruit, and the wall releases warmth through frosty nights.

Right plant, right place

Planting & stewardship

How to help Oro Blanco grapefruit hybrid thrive

  1. 1

    Verify both the named cultivar and rootstock on the nursery tag before planting.

  2. 2

    Whitewash newly exposed bark and protect cold-sensitive trees during hard freezes.

  3. 3

    Feed in several light applications during the active season rather than one heavy dose.

  4. 4

    Let fruit color and flavor—not a calendar date alone—confirm harvest readiness.
