Uncover the Truth About Redbud Trees Before Planting

It's easy to see why redbud trees are so popular with gardeners. The burst of color they provide seems almost too good to be true for such a small, unassuming tree. However, as is often the case in life, beauty has its price. Redbud trees offer outstanding benefits but also come with potential drawbacks that you should weigh carefully before planting.

We'll explore why they are so visually appealing along with factors like their shorter lifespan and particular growing needs. Armed with the complete picture, you'll know if the pros of redbud trees outweigh the cons for your garden.

Redbud Tree Basics

Native to eastern and central North America, redbud trees (Cercis canadensis) are deciduous trees in the bean family. They typically grow 15-30 feet tall and wide in an upright, vase-like shape. Their branches are lined with glossy, heart-shaped leaves that emerge reddish-purple before transitioning to green and then turning yellow in autumn.

The real showstopper of redbud trees are the profuse clusters of pea-like flowers that blanket their branches in spring before the leaves unfurl. These blooms come in shades of bright magenta-pink, lavender-purple, and even white depending on the variety.

There are both native redbud tree species and cultivated hybrid varieties available. Some popular cultivars like 'Forest Pansy' have leaves that remain deep reddish-purple all season. Weeping varieties like 'Ruby Falls' have gracefully cascading branches perfect for small yards.

The Appeal of Redbud Trees

Spring Blooms

One of the best features of redbuds is that they are among the earliest trees to bloom each spring. While other trees are still dormant, redbud flowers will be lighting up the landscape as early as March in some areas of the country.

The profusion of showy, intensely colored blooms lasts for several weeks from March through May depending on your location and the weather. Few other trees offer such a lengthy and dramatic floral display right at the beginning of spring.

You can extend the bloom time even further by planting a combination of early, mid, and late-blooming redbud varieties.

Heart-Shaped Leaves

The foliage of redbud trees is just as showy as the spring flowers. The heart-shaped leaves emerge in unique color combinations of red, bronze, purple, and green before transitioning to a solid green. Shade-loving varieties like 'Forest Pansy' retain deep purple foliage all season.

In fall when most other trees sport yellow leaves, the leaves of the redbud will turn bright gold, orange, or yellow depending on the variety. This gives another splash of late season color to the landscape.

Compact Size

With their modest 15-30 foot height and spread, redbud trees are suited even for small residential landscapes. Unlike many flowering trees that can overpower a small suburban yard, a redbud will fit right in.

Their relatively short stature also makes redbud trees ideal for planting beneath overhead utility lines. Weeping varieties can even be utilized in planters and tree rings.

The compact size and vase-like form means redbuds don't require much pruning or maintenance to control their shape.

The Drawbacks of Redbud Trees

Short Lifespan

One major downside of redbuds is their relatively short life expectancy. On average, redbud trees only live around 20-30 years. This is significantly less than the 60+ year lifespan of many popular landscape trees.

Some contributing factors to the redbud's shorter life include:

• Susceptibility to canker diseases that can girdle and kill branches and entire trees.
• Vulnerability to wood boring pests like carpenterworms that can damage the trunk.
• Intolerance of overly wet soils which can lead to fungal root rot.

While proper site selection and care can help maximize the longevity of redbud trees, they may still only live for a couple decades in the landscape.

Messy Seed Pods

The spring floral display of redbuds gives way to somewhat messy green seed pods several inches long. These mature in summer and fall to a dry brown before splitting open to release their seeds.

Fallen seed pods tend to accumulate heavily beneath the tree, requiring regular clean up. You'll also likely find volunteer seedlings sprouting up in the surrounding landscape from seeds spread by wind and birds.

Particular Growing Needs

Although they are adaptable to various conditions, redbuds do have some particular requirements for optimal growth and longevity.

Redbud trees need:

• Well-draining soil and will decline if left in wet, clay-like soil.
• Neutral to slightly acidic soil pH between 6.0-7.0.
• Consistency in moisture - dislike dry spells followed by heavy watering.
• Shelter from intense wind which can damage branches.

Exposure is another consideration, as different varieties have preferences for sun or part shade. In hot climates, afternoon shade is recommended.

Meeting the specific needs of redbuds requires more forethought and preparation than some tougher, more adaptable trees.

Tips for Growing Redbud Trees

Proper planning and care from the start can help your redbud tree thrive for years to come.

Site Selection

Choosing an appropriate site for your redbud is key. Pick a spot with:

• Full sun to part shade depending on the variety.
• Well-draining soil or create a raised planting area if drainage is poor.
• Shelter from strong winds yet good air circulation.
• Sufficient room for future growth without encroaching on structures.

Watering Guidelines

Redbuds should be kept consistently moist but not waterlogged their first two years after planting. After establishment, water only during drought periods. Mulching helps regulate soil temperature and moisture.

Addressing Nutrient Deficiencies

Redbuds are prone to iron and manganese deficiencies when the soil pH is too high. Applying a chelated supplement can correct this. Have the soil tested to determine any adjustments needed.

Pruning for Shape and Health

Prune only as needed to maintain shape, thinning out crossing branches and removing any damaged or diseased wood. Avoid heavy pruning that can introduce disease.

Protecting from Pests and Diseases

Major pests include Japanese beetles, aphids, leafhoppers, flatheaded appletree borer, and carpenterworms. Diseases include verticillium wilt, canker, root rot, and anthracnose. Maintaining vigor through proper care is the best defense.

When weighing whether to plant a redbud tree, consider these key points:

• Redbud trees offer outstanding spring blooms, heart-shaped foliage, and compact size perfect for small yards.
• However, their relatively short lifespan of just 20-30 years is a definite downside.
• They also drop messy seed pods and require more specific care compared to tougher tree species.
• With proper site selection and optimal care, you can maximize a redbud tree's health and longevity.
• Alternatives like serviceberry, fringe tree, and dogwood offer similar spring blooms on longer-lived trees.

While stunning when in full flower, redbud trees represent a fairly big investment for a small landscape tree with a fleeting presence. However, if you go in understanding their potential drawbacks, redbuds can certainly bring ample springtime joy for the years they grace your garden.
