The care sheet
The constants — what stays true in every season.
Full sun
Full sun helps retain compact internodes.
Moderate
Avoid waterlogging, but don't let dry out.
Balanced
Avoid nitrogen overload; encourages coarse growth.
Structural in spring, maintenance summer
Can defoliate after major prune; plan ahead.
Spring or Autumn
Best trained via clip-and-grow due to fragility.
Every 2-3 years
Use fast-draining mix; dislikes wet roots.
Cuttings or seed
Softwood cuttings difficult; layering more reliable.
Wood is brittle when cold; avoid manipulation.
May sulk in extended heat - provide shade if stressed.
