The bark of Betula 'Polar Bear' develops its stunning white complexion at a young age and is said to look like a magnificent polar bear due to its impressive branches. More commonly known as Erman’s birch trees, they will grow to 6 x 4 metres in 20 years and are suited to exposed inland sites.

The Polar Bear tree is tolerant of most except extreme soil types and will do well in sunny to partly shaded spots. The foliage is dark green and emerges alongside long attractive yellow/brown catkins in the Spring. The glorious yellow autumn colours that emerge compliment the white exfoliating bark making Betula ermanii 'Polar Bear' a beautiful year round, feature tree.

Planting Advice for Betula Ermanii Polar Bear trees

Our pot grown Polar Bear Birch trees can be planted at any time of the year. Start by removing weeds and grass within a metre of your desired planting hole. Dig a square hole as deep as your root mass and approximately 2x as wide. To help the tree establish more effectively, sprinkle root grow in the hole.

Remove the pot, gently loosen the roots and place into the planting hole. Mix 50% of the original soil with 50% compost, fill in the hole and firm around gently. Avoid banking the soil up around the collar of the tree. Unless it's a multi stem form, we recommend planting Polar Bear Birch trees with a stake and tie - instructions are in the planting guide.

Aftercare Advice for Betula Polar Bear trees

If you're planting in spring or summer, water well for the first few months. Increase watering if there are extended periods of hot or dry weather. If planting in autumn, you may only need to water a little. Unlike other species, Birch trees would rather be in wet soil than dry. Irrigation kits make it easier.

Once planted, keep the area free of competing weeds and grass for the first couple of growing seasons. If your area is prone to rabbits, use a rabbit guard. To keep the white bark on this Birch looking its best, you can wash it using a pressure washer (on a gentle setting), garden hose or slightly soapy water.

Pruning Advice for Betula Ermanii Polar Bear trees

Established Polar Bear Birch trees do not require pruning and do not take well to hard pruning. Hard pruning leads to increased light penetration which in turn results in increased soil temperature and decreased moisture levels. Simply remove the lateral shoots to maintain a clear trunk and prune any diseased or damaged branches. Pruning should be carried out in late summer to mid-winter. Birch trees bleed heavily at all other times of the year, especially late winter.

There's no need to be in to receive your trees and you can request where they are left via the checkout.

There is a slightly longer timescale on pleached and mature trees (trees over 2.5m in height) because we group orders together by geographic area for specialist delivery - we will contact these customers to notify them of the delivery date and whether the delivery driver needs assistance.

Gift trees and those required by a specific date can be accommodated with pleasure, although we accept no legal responsibility for late deliveries.

Our nursery is a busy despatch centre, so please make an appointment to collect or view trees.  For collections, despatch charges will be refunded.

Below are definitions of various forms, which refer to the shape of the tree defined by the pruning it has received. For more advice, please contact us.

Single Stem / Pruned and shaped: Classic shaped tree with a single stem that has had pruning to help create a beautiful, natural shape.

Top grafted: A height noted next to this form refers to the length of clear stem, which will not grow taller. Only the head of branches will develop. Top grafted trees do not require complicated pruning and are ideal for small spaces.

Multi Stem: A multi stem tree is has two or more stems arising from or near ground level, growing from one root system. Take care to buy a true multi-stem like all ours and not those that are 3 saplings in a pot to cheaply imitate them.

Feathered: A feathered tree has branches from the bottom of the trunk all the way up. These branches can be removed if a clear stem is required.

Bush: A plant with many stems low down, rather than one clear stem.

Climber: A plant that is a natural climber and will be delivered usually running up a bamboo cane, ready to position in the garden.

Standard Tree: A more mature tree with an upright clear stem of approximately 1.8m-2.0m (measured from the soil to the lowest branch), which supports a branched crown. Standards are available in different forms relating to their girth size (circumference of the stem measured 1m above soil level), not height.

Standard  either 6-10cm or 8-10cm girth, approximately 2.5-3.0m in height
Premium Standard  10-12cm girth, approximately 3.0-3.5m in height
Heavy Standard  12-14cm girth, approximately 3.5-4.5m in height
Extra Heavy Standard 14-16cm girth approximately 4.0-6m in height
