Planting & Care

Select a spot with full sun exposure and dig a hole twice as wide as the root ball but equally deep, ensuring the graft union sits at soil level. Amend the soil with organic matter and water thoroughly after planting. For containers, use a citrus or cactus-blend potting mix with added perlite for drainage, and choose a pot 1–2 inches wider than the nursery container. Water when the top 2 inches of soil dry out, avoiding soggy conditions that invite root rot. Prune annually in early spring to maintain size and shape, and fertilize during spring and summer with an avocado-specific formula. In winter, move potted trees indoors when nighttime temps drop to 50°F, ensuring they receive bright light and hand-pollinate flowers for fruit production.
