The Persea americana ‘Hass’ tree features a foliage canopy that is low and dense with 3-10″ dark green leaves alternately arranged. Because these trees can get quite large over time, a planting area of 25—30′ is recommended. In order to promote flowering and produce fruit, Avocados need very little chilling time between 32—45°F during the dormant season. The ‘Hass’ variety does best in a southern-facing, full-sun location that has well-drained soil.’Hass’ trees are considered “self-fruitful” and do not need a partner tree for cross-pollination to produce a fruit crop when grown solo. But with an opposite partner tree planted close by, a more successful and higher volume crop is enhanced. Avocado fruit has to be harvested by hand so if it isn’t picked, it won’t fall off the tree and it won’t ripen. Fortunately, the tree can be used as a storage unit for as long as 8 months. Harvest can begin as early as February and as late as September. And the longer the fruit stays on the tree, the richer the taste.
