Location:

Outdoor

Position:

Birches like a lot of light, although some shade is advisable in the hottest areas or in midsummer

Watering:

Requires consistently moist soil; ensure that only the surface is dry before watering. Do not let the pot dry out and ensure that your pot does not water log.



Feeding:

Every two weeks from early spring till the end of summer. Use a balanced fertiliser.

Leaf and Branch Pruning:

Trim back shoots to the first pair of leaves throughout growth. It is wise to make large pruning cuts late in the season, as birches "bleed" profusely when the sap begins to run.

Re-potting & Growing Medium:

Birches younger than age 10 will need repotting every two-three years. Older trees need repotting as necessary. Repot in spring, before bud burst, using free-draininig soil mix. Use 3 part Akadama to 1 part Pumice or Fuji Grit.

Wiring:

Care should be taken to protect the bark when wiring.
