Horne's Birch

Betula x hornei

Horne's Birch (Betula x hornei) is a hybrid species of birches found in North America's temperate and sub-alpine forests. It was named in honor of Canadian botanist Harold Horne. It is a fast-growing, medium-sized tree, reaching heights of up to 40 feet. The horn-shaped, glossy dark green leaves turn yellow to orange in fall. The bark is silvery-gray, with large black horizontal markings. The bark peels on the lower trunk, revealing creamy-white to orange inner bark. It features small, pendulous male catkins and female spikes that produce small triangular winged fruits. Horne's Birch is considered an ornamental tree, perfect for planting in parks and gardens. It is recommended for gardeners who are looking for a unique and eye-catching addition to the landscape.

watering

Horne's Birch (Betula x hornei) should be watered once weekly, and between 1/2 to 1 inch (1-2 cm) of water is recommended for each plant. Water deeply to ensure that the soil is evenly moist throughout the pot and to encourage root growth. During summer months, extra water may be needed to prevent plants from wilting if temperatures are higher than average. Reduce watering in colder months, but keep an eye on the soil moisture level—it should remain evenly moist, not soggy or dry.

sunlight

Horne's Birch (Betula x hornei) is native to North America and grows best in full sunlight or partially sunny locations. It prefers slightly acidic, moist soils in areas with cool climates and mild summers. The tree typically does best when exposed to at least 6-8 hours of direct sunlight each day. During the summer and early fall months, sunlight hours can be extended to provide even more benefits to the tree. Bright but indirect light in the early morning and late afternoon can also be beneficial. During the winter, the tree should be exposed to as much sunlight as possible during the day.

pruning

Horne's birch should be pruned in late winter or early spring before new growth begins. Prune young rooted cuttings to encourage branching and remove dead branches. Remove any broken stems and branches and any diseased foliage. Cut back taller or leggy branches to encourage denser growth. Prune a few older branches each year to encourage new growth and reduce the overall size of the tree. When pruning, avoid removing too much of the tree’s branches, as this weakens the structure. Avoid pruning more than 1-third of the tree’s total branches and leaves in 1 season.
