Abiu

Why it works here

Abiu is a Sapotaceae relative of the canistel and sapodilla, and it grows about as far north as Palm Beach County, which puts Stuart right at the edge of its comfort zone. The fruit is bright yellow with a translucent, custard-like pulp that tastes like caramel flan, so it earns its spot as a conversation-piece tree. In a Florida-Friendly design I treat it as a specimen for a warm microclimate, tucked near a south wall or under taller canopy that blocks cold wind.

Care

Give it consistent water, especially through the dry spring months, but plant it high in well-draining soil so the roots never sit soggy. Feed with compost and a balanced organic fertilizer a few times through the warm season, and keep a good ring of mulch out to the dripline to hold moisture and feed the soil. Our high-pH sandy soil can lock up iron and other micronutrients, which shows up as chlorosis, meaning the leaves yellow between the veins from a nutrient the roots cannot pull in, so an organic foliar feeding through the growing season helps. Prune lightly just to shape and to keep it low enough to harvest.

Common problems

Cold damage: this is the real caveat, a hard freeze can knock back or kill a young abiu, so site it in your warmest spot and be ready to cover it on a cold night.

Chlorosis on alkaline soil: correct with compost, mulch, and organic micronutrient foliar feeding rather than letting it limp along.

Sunburn and wind on young trees: the thin bark and tender growth of a young tree can scorch, so a little afternoon protection and a windbreak while it establishes go a long way.
