The traditional avocado is a large, leafy tree but there are smaller forms ideal for backyard orchards, courtyards or container growing. For a guaranteed crop buy a named, grafted variety, which should fruit in three to five years from planting. If space permits, plant several varieties to extend harvest times and aid pollination. ‘Wurtz’ is a naturally dwarf form, suited to small gardens that has rough, pear-shaped fruit. It reaches around 3-4m high and wide. Avocado ripens off the tree with harvests in late summer and autumn.
Aspect Avocado trees need a bright, sunny location with shelter from strong winds. Ideally, they should have sun from the morning onwards but can tolerate a little afternoon shade especially in summer and should be protected from cold and frost. Windy conditions when fruit is forming can cause fruit drop and a drastic reduction in crop size.
Soil Avocado grow in a wide range of soils but grow best with good drainage in deep, fertile soils. Keep soil well mulched. In containers use a high quality potting mix such as Seasol Advanced Potting Mix. It’s ready to use mix means that you don’t have to add anything additional to it. Remember to water in with Seasol to help reduce transplant shock and aid plant establishment.
Climate They do best in warm, frost-free locations and are well suited to gardens in warm coastal climates. In cool areas, grow in a warm micro-climate.
