Purpus' Birch

Betula x purpusii

Purpus' Birch (Betula x purpusii) is a rapid-growing hybrid tree renowned for its striking ornamental value. It has glossy, dark purple leaves that contrast brilliantly against its white bark, which gives rise to its common nickname of 'Purple-leaf Birch'. While it is slow to attain its full height, a mature tree can reach up to 20 feet in height. It is a hardy species and grows well in most soils, though it prefers acidic soils. It does best in areas with cooler summers and full sun exposure. It is also drought-tolerant once established. An outstanding choice for adding color and texture to a landscape, Purpus' Birch makes an excellent feature tree for yards and public areas.

watering

Eastwood's Birch (Betula x eastwoodae) should be watered regularly but deeply. Water until the soil is saturated and allow it to dry out slightly between waterings. In the spring and summer months, water Eastwood's Birch every 7-10 days; in the fall and winter months, reduce the frequency of watering to every 15-20 days. It is important to note that if the soil dries out too much, the leaves may start to turn brown. If this happens, increase the frequency of watering and make sure to saturate the soil.

sunlight

Eastwood's Birch loves full sun and should receive at least 6-8 hours of direct sunlight each day. When providing sunlight, it is important to have Eastwood's Birch planted in an area that receives sun throughout much of the day, away from shade trees and structures. During the hottest months of the year, it is recommended that this species be placed in slightly dappled, or indirect sunlight to help avoid leaf burn.

pruning

Eastwood's Birch should be pruned while the plant is still young, usually within the first 3 to 5 years after planting. Pruning should be done in late winter or early spring before the buds start to swell. When pruning Eastwood's Birch, remove all dead, diseased, and broken branches and remove any suckers. To promote a healthy dense canopy, selectively prune branches that are crossing, rubbing, or horizontally growing. Do not prune more than 1-third of the branches in any 1 year. Pruning younger branches should be done at an angle, and older branches should be cut close to the trunk.
