What Soil Mix Works Best for a Happy Tree?
Rich, well-draining soil with high organic content. Good drainage is essential for Happy Tree to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Happy Tree?
Feed Happy Tree 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 Happy Tree?
Choose a spot with full sun to partial shade and rich, well-draining soil with high organic content. Avoid low spots where water collects after rain.
Happy Tree is suited to USDA Zone 9a – 11b.
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 Happy Tree?
Happy Tree can spread to about 20 ft (6.1 m) and reach about 30 ft (9 m) tall. Space plants about 20 ft (6.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

How Do You Prune a Happy Tree?
Prune Happy Tree while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.
If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.
