Silver Birch Betula pendula subsp. pendula 'Tristis'
ABOUT
The plant commonly known as the Silver Birch 'Tristis' is a captivating and elegant deciduous tree that takes on a weeping form, distinguished by its slender and pendulous branches. The bark of the tree is particularly striking, showcasing a white color that peels off in papery strips, providing a stark contrast against its surrounding landscape. The leaves of 'Tristis' are small and somewhat triangular in shape, displaying a fine serrated edge that adds a delicate texture to the overall appearance. During the growing season, the foliage emerges in a bright green color, transitioning to a vibrant yellow hue as autumn approaches, offering a seasonal display that enriches its visual appeal. Catkins, which are long, slender, and cylindrical flower clusters, appear as the first signs of spring arrive, initially presenting a yellowish-green appearance before turning into a darker shade as they mature. These catkins add a subtle ornamental character to the tree. The combination of the tree's weeping habit, white bark, and seasonal color changes contributes to its popularity as a landscape plant, favored for its unique structure and year-round interest.

WaterThe Weeping Birch (Betula pendula 'Tristis') prefers consistent moisture, particularly in the growing season. Aim to water young trees deeply once or twice a week, making sure the soil is moist but not waterlogged. Mature trees typically require less frequent watering. Provide about 1 to 2 gallons per watering session, depending on weather conditions. In times of drought or extreme heat, increase watering frequency to maintain soil moisture.
LightWeeping Birch flourishes in full sun, where it can receive at least six hours of direct sunlight daily. Planting it in an unobstructed area that provides ample sunlight will ensure optimal growth and health.
TemperatureThe Weeping Birch is hardy and can tolerate a wide range of temperatures, from cold winters to warm summers. It can survive minimum temperatures as low as -40°F and maximum temperatures well above 100°F. However, the ideal temperature range for this birch is between 30°F and 70°F for healthy growth.
PruningPrune the Weeping Birch to remove any dead or damaged branches, and to maintain its graceful shape, typically during the dormant season in late fall or winter. Pruning every 2 to 3 years is generally enough for mature trees; however, perform structural pruning on younger trees more frequently to establish a strong frame. Always prune just outside the branch collar to avoid damaging the tree.
CleaningAs needed
SoilThe European Weeping Birch (Silver Birch) thrives best in moist, well-drained soil rich in organic matter. The ideal soil mix for Silver Birch is one-part loam, one-part peat or leaf mold, and one-part sharp sand or perlite to ensure proper drainage. Silver Birch prefers a slightly acidic to neutral pH, around 5.5 to 7.0.
RepottingEuropean Weeping Birch trees are typically not repotted as they are large landscape trees. Instead, they may occasionally require transplanting to a larger space outdoors. Such trees are usually established from young saplings and are not suited to container growth that would require repotting.
Humidity & MistingEuropean Weeping Birch is adaptable but prefers a moderate to high humidity environment. While specific humidity levels aren’t crucial when grown outdoors, maintaining a natural moisture level in the air around the tree will contribute to its health.

Life cycleEuropean White Birch 'Tristis' starts its life as a seed, which requires stratification to germinate. Upon germinating in a suitable environment—which includes moist, well-drained soil, and full to partial sunlight—the seedling establishes and begins to grow, developing a characteristic slender trunk with pendulous branches. As a young tree, it goes through a rapid growth phase, during which it develops its silvery-white bark and serrated foliage. Reaching maturity after several years, it enters a reproductive stage where it produces catkins that release numerous wind-dispersed seeds in autumn. As an adult, the European White Birch 'Tristis' experiences seasonal changes with foliage turning yellow in fall before leaf drop and can live up to 80 years or more. Ultimately, the tree's life cycle concludes as it succumbs to age, environmental stress, or disease, and decomposes, returning nutrients back to the soil.
PropogationPropogation time
Spring-Early Summer
The most popular method of propagation for the European White Birch 'Tristis' is through seed collection and sowing. Seeds are typically collected in late summer to autumn once the cones have begun to disintegrate, allowing for easy extraction of the small seeds. After collection, seeds require a period of cold stratification to break dormancy, which involves mixing the seeds with some moist sand and storing them in a refrigerator at around 34-41 degrees Fahrenheit (1-5 degrees Celsius) for several weeks. Once stratified, the seeds are sown in well-draining soil and lightly covered, as they require some light to germinate effectively. Germination usually takes place in the spring, and seedlings should be kept in a sheltered location with protection from strong winds and direct sunlight until they are robust enough to be transplanted into their permanent positions.
