Guide to Redbud Trees: How to Care for a Redbud Tree

The eastern redbud tree (Cercis canadensis) is a deciduous tree named for its bright and showy flowers. Most varieties have magenta, lavender, or rosy pink blossoms, and a few varieties have white flowers. The tree blooms in springtime. In summer, it has deep green leaves, which in the fall turn yellow or amber.

Eastern redbuds are medium to small trees. They have a moderate growth rate, averaging around ten feet in the first five years after planting. When fully mature, they reach twenty to thirty feet high and their branches average about twenty feet in width. It is a popular ornamental tree that can add bright color to landscaping.

Eastern redbuds come in a variety of sizes and flower colors, including the following:

1. 1. ‘Ruby Falls’: This common redbud is a small tree with red or purple flowers. In the spring, its leaves are a deep red or burgundy color. The leaves are deep green in summer.
2. 2. ‘Texas White’: Named for its flowers, this variety has bright white flowers and green, shiny leaves.
3. 3. ‘Forest Pansy’: A smaller tree with pink flowers, the ‘Forest Pansy’ redbud has heart-shaped green leaves that turn red, burgundy, or orange in the fall.
4. 4. ‘Ace of Hearts’: If your garden is small, consider this tree. This redbud is a dwarf tree with violet-pink flowers. The leaves are a distinctive heart shape and dark green. This variety does better in USDA Hardiness Zones 5–9.
5. 5. ‘Merlot’: This is a compact variety of redbud with rosy pink flowers and shiny green and red leaves.
6. 6. ‘Silver Cloud’: A showy redbud cultivar, ‘Silver Cloud’ has white and pink variegated leaves and rosy-pink flowers that bloom on bare branches.

The redbud tree is low-maintenance and typically survives fifty to seventy years with proper care. Here are several areas of care to consider for your redbud:

• Climate: Check whether redbud trees can successfully grow in your area. The tree is native to the eastern regions of North America but will grow across USDA Hardiness Zones 4–9.
• Plant: For the best results, plant young trees in early spring. While the tree is fairly hardy, the root ball is delicate. If you transplant a mature tree, the roots may die, killing the tree.
• Soil: Plant the redbud in well-draining soil and fertilize it annually.
• Sunlight: When planted in full sun, the redbud will experience fuller, more vibrant blooms; however, some shade is recommended during the hot summer days. The redbud can tolerate partial shade but won’t grow well in fully shaded areas.
• Water: Keep the soil evenly moist, but don’t overwater your redbud. If the roots sit in water-logged soil, it can lead to fungal infections.

While redbuds typically require minimal care, be on the lookout for a few common issues and pests, such as:

1. 1. Botryosphaeria canker: Apply a layer of mulch in summer to help preserve soil moisture, as prolonged drought can stress trees and lead to cankers, signs of a pathogenic fungi. If cankers appear, you should prune the infected branches about six inches below the visible canker.
2. 2. Leaf-eating insects: Bugs like caterpillars, weevils, and leafhoppers can infest redbud trees. Trim leaves damaged by insects and apply the most appropriate insecticide for the infestation.
3. 3. Verticillium wilt: Yellow wilted leaves are a sign of this fungal disease that attacks trees through their root system. To prevent this affliction, keep the soil moist but don’t overwater the tree. If the tree shows early signs of wilt, prune the affected branches. If wilt has infected a majority of the tree, it may not survive.
