Step-by-Step Growing Guide
Avocados are subtropical trees demanding exceptional drainage — they are among the most sensitive of all fruit trees to waterlogged conditions, suffering root rot within days. In-ground planting is only suitable for zones 9–11. Grafted trees are essential for fruiting within 2–4 years; seed-grown trees may take 10–15 years and often produce inferior fruit. Plant on raised mounds or slopes in well-drained, slightly acidic soil (pH 6.0–7.0). Avocados are type A or type B flower producers — plant one of each for cross-pollination and maximum yield. Feed with a balanced citrus or avocado fertilizer supplemented with zinc and boron, which are commonly deficient. Water deeply but infrequently, allowing soil to partially dry between waterings — shallow, frequent irrigation promotes root rot. Mulch broadly but keep mulch away from the trunk. Protect from frost with fabric covers; even "hardy" varieties are damaged below -3°C.
