What Soil Mix Works Best for a Uvaria concava?

Well-draining loamy soil with added organic matter for moisture retention. Good drainage is essential for Uvaria concava to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Uvaria concava?

Feed Uvaria concava every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Where Should You Plant a Uvaria concava?

Choose a spot with partial shade to full sun and well-draining loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Uvaria concava is suited to USDA Zone 13b.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

How Far Apart Should You Plant a Uvaria concava?

Uvaria concava can spread to about 8 ft (2.4 m) and reach about 10 ft (3 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.
