Hass Avocado

Persea americana 'Hass'

The classic California avocado tree! Silky, creamy-textured fruits with a rich nutty flavor and high oil content mature over a very long season, from April to October. Distinctive dark green, pebbly skin turns purplish-black as the fruit ripens after harvest. The type A flowers are self-fertile, but planting more or a complementary variety such as 'Sir Prize' may boost fruit set.

Botanical PronunciationPER-see-uh a-mer-ih-KAY-na HAS
LoreThough widely misspelled as 'Haas', this popular avocado variety is in fact named 'Hass', as it is the namesake of postman Rudolph Hass, who planted the original tree as a seedling in his Southern California grove in the mid-1920s. The Hass mother tree died and was removed in the fall of 2002. A plaque now marks the site where it lived, on West Road in La Habra Heights, California. Avocado trees typically carry concurrent crops; they flower and set fruit while the fruit that was set the previous spring is nearly ready to be harvested, having spent 12 to 18 months reaching maturity.

Watering NeedsWater regularly - weekly, or more often in extreme heat or containers.

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.
