Kenai Birch

Betula kenaica

The Kenai Birch (Betula kenaica) is a medium-sized deciduous tree with a bushy crown located along the southeastern Alaska coastline. Its pale yellow-white bark adds a touch of brightness and the tree can reach up to 50 feet tall upon maturity. Its deep green foliage, which displays a unique colour in the autumn lasting until spring, forms an attractive oval crown and offers excellent privacy and shade throughout the year. The tree is tolerant of most soil types and can easily withstand extreme cold temperatures and coastal conditions allowing this species to spread naturally. The Kenai Birch also produces abundant, wind pollinated clusters of pendulous catkins adding an additional dimension of beauty and grace. It’s a great addition to any garden and its distinct look will surely draw attention!

watering

Heartleaf Birch (Betula cordifolia) is low maintenance and easy to care for. The plant should be watered once every 1-2 weeks. Water deeply so that the soil becomes saturated and allow the soil to dry out between waterings. During the growing season, water the plant more often, but still allow the soil to dry out somewhat between waterings. During the winter months, reduce watering to once a month. If the soil feels dry 1-2 inches below the surface, it is time to water the plant again.

sunlight

Heartleaf Birch typically grows best in full sun and needs a minimum of 6–8 hours of direct sunlight per day. This plant species prefers cooler climates with humid summers and a minimum of -20°F in winter. Make sure to protect Heartleaf Birch from strong winds, as this species can become prone to breaking if exposed to strong winds for a prolonged period of time. To keep this species healthy, water the roots deeply but avoid overwatering.

pruning

Heartleaf Birch should be pruned lightly in early summer, if necessary. Pruning should only be done to remove dead or damaged branches, or to shape the plant. When pruning, make sure to make clean cuts just above the node or junction of a branch. Avoid over-pruning, since this species may be slow to regrow branches that have been cut.
