Persea americana 'Hass'
Pronunciation: PER-see-uh a-mer-ih-KAY-na HAS
|Description||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.|
|Watering||Water when top 3 inches of soil is dry.|
|Mature Size||Reaches 15-25 ft. tall, 15-20 ft. wide; easily kept smaller with pruning.|
|Care||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.|
|Lore||Though 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.|
