Bottlebrush Buckeye Plant Care

Bottlebrush Buckeye (Aesculus parviflora) belongs to the Sapindaceae family within the Aesculus genus. Bottlebrush Buckeye is native to the southeastern United States. Bottlebrush Buckeye is also known as Dwarf Buckeye.

Bottlebrush Buckeye displays a large deciduous tree growth habit, reaching up to 50 ft tall with a spread of approximately 30 ft. Bottlebrush Buckeye produces showy clusters of white, pink, or red flowers.

Leaf size: approximately 8 inches.

Water a young or newly planted Bottlebrush Buckeye every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Bottlebrush Buckeye thrives in full sun to partial shade.

Aesculus parviflora tolerates temperatures of 60–90°F. Bottlebrush Buckeye prefers humidity levels of 40–70%.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Bottlebrush Buckeye to prevent waterlogging, which leads to root rot and fungal issues.

Feed Bottlebrush Buckeye 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.

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

Bottlebrush Buckeye is suited to USDA Zone 13a.

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.

Bottlebrush Buckeye can spread to about 30 ft (9.1 m) and reach about 50 ft (15 m) tall. Space plants about 30 ft (9.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Bottlebrush Buckeye 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.

Bottlebrush Buckeye is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Bottlebrush Buckeye can be propagated through seeds.

Bottlebrush Buckeye is susceptible to leaf miners, scale insects, horse chestnut scale. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Bottlebrush Buckeye grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Bottlebrush Buckeye is native to the southeastern United States. In cooler regions, grow Bottlebrush Buckeye as a houseplant or bring it indoors before the first frost.
