Avalanche Birch (Betula x ‘Avalzam’) offers crisp white bark and glossy green leaves, creating an elegant focal point for lawns, borders, or near water features. Its multi-stemmed form features bark that initially shows tan and pink hues but matures to a striking bright white, contrasting with emerald leaves that turn a warm golden in autumn. Reaching a mature height of about 50 feet and a spread of 30 to 40 feet, it stands out for superior pest resistance, including tolerance against the bronze birch borer. Its fast growth and easy adaptability to various light conditions make it an appealing choice for gardens seeking color and strong vertical interest.
Avalanche Birch demonstrates moderate drought tolerance once established, though it prefers evenly moist, slightly acidic soil. It is resilient in windy or challenging environments and is hardy in zones 4 through 7. This birch benefits birdlife by offering both shelter and nesting spots, but it is resistant to deer browsing. Its smooth trunk and upright habit lend themselves to a refined look as a single lawn specimen or grouped for a nature-inspired grove effect. Use it in cottage gardens, along driveways, or for framing architectural elements.
Avalanche Birch Care
Position Avalanche Birch in full sun or partial sun, providing about six hours of daily light. Plant in well-drained, moderately acidic soil, and water consistently during the first couple of growing seasons, especially in periods of high heat. A general-purpose, slow-release fertilizer in early spring can enhance leaf color and trunk vigor. Mulch around the base for root protection, soil moisture retention, and weed control. While it handles occasional dryness, consistent moisture helps uphold its signature bark color and keeps foliage in prime condition.
Pruning typically entails removing damaged or crossing limbs to maintain an appealing silhouette. Tackle any shaping in late winter to avoid excess sap flow. If grown in a container, select a sizable pot with proper drainage and refresh the growing medium every few years. Most gardeners otherwise let the tree develop its natural form with minimal intervention.
Avalanche Birch Spacing
When creating a striking grove or a loose row, position trees about 20 to 25 feet apart so each trunk can shine. For a single specimen in a smaller yard, leave at least 30 feet of clearance on all sides. If container-cultivated, start with a pot diameter of 18 inches or larger, upgrading as roots fill out the space. This approach ensures ample room for Avalanche Birch to exhibit its smooth bark and graceful canopy.

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
