Lamb Hass Avocado

Persea americana 'Lamb Hass'

This upright, compact, and prolific tree produces bigger fruit than Hass, and matures a month later. Dark green, pebbly skin turns purplish-black as the fruit ripens after harvest, from May to November. Easy to peel, revealing its exceptionally rich flavor and creamy texture inside. The type A flowers are self-fertile, but planting more or a complementary variety such as 'Sir Prize' may boost fruit set.

Provide unamended, well-drained soil, and a wind and frost-sheltered site. Apply a thick layer of mulch to conserve moisture, avoiding the trunk. Water deeply and regularly during first growing season to establish an extensive root system; reduce frequency once established. Periodic leaf drop is normal; allow to remain as mulch. Apply a slow-release fertilizer in spring after flowering.
