Betula nigra 'Black Star' Tree

River Birch Trees
  • From £49.99 (ex VAT)
Loading...

One of the best Birch trees for interesting bark, Betula nigra 'Black Star' displays shades of pink to brown in the rugged, papery, peeling bark. The tactile bark darkens with age to create more variety in colour and provides year round interest. Glossy green foliage forms an airy canopy and turns yellow in autumn.

Betula nigra 'Black Star' has a neat shape and in its single stem form a height and spread of 8 x 4 metres in 20 years can be expected. This Birch is an excellent choice for adding texture and interest to tricky moist or damp soils.

Planting Advice for Betula nigra Black Star Trees

Our pot grown Black Star 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 River Birch trees with a stake and tie kit to ensure the roots are well anchored - instructions are in the planting guide.

Aftercare of Betula nigra Black Star Trees

If you're planting River Birch 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 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 Betula nigra Black Star Trees

Established Black Star Birch trees do not require pruning and they do not take well to hard pruning. Hard pruning leads to increased light penetration of the roots 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.

The product table at the bottom of the page gives the forms and sizes available for this variety. Please note, photos are a guideline as all plants are unique. Below are definitions of terms:

Supplied Size: Height measured from the top of the pot.

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 branches of the 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
