Silver birch
Stake young trees for the first two years in an exposed site, and water deeply through the first two summers while the root system establishes.
Care
Best bark colour and canopy density develop in an open, sunny position.
Water well for the first two summers; established trees rarely need extra watering except in prolonged drought.
Adaptable, well-drained soil of most types; tolerates poor or sandy ground but dislikes permanent waterlogging.
Prune only in late summer or autumn, never in winter or spring — this genus 'bleeds' heavily from cuts made while the sap is rising.
No feeding once established — birches grow on poor, thin soils by nature. Keep the base clear of grass for the first few years instead, which is what actually speeds a young tree away.
From seed sown in autumn in a pot left outdoors; the tiny seed needs light and cold to germinate. Named white-barked selections are grafted, so a seedling will not necessarily have the same bark.

Common problems
How to spot it. Orange-yellow pustules on leaf undersides in late summer.
What to do. Rake up and dispose of fallen leaves; rarely serious enough to need treatment.
How to spot it. Sooty mould on leaves, cars or paths beneath the tree.
What to do. Tolerate where possible; encourage predators.
How to spot it. Bracket fungi at the base, dieback.

Questions
Silver birch: is it hardy?
H7: Fully hardy anywhere in the UK. It survives below −20 °C.
Can it grow in a pot?
A full-sized tree unsuited to long-term pot culture; multi-stem forms can be grown on for a few years in a very large container.
Silver birch: when do you prune it?

Silver birch: when does it flower?
In the climate of UK it flowers in March–April.
When do you feed it?
