- Daily or twice daily during heat waves.
- Use low-nitrogen or potassium-rich feed to support wood maturity.
- Avoid heavy pruning; light shaping only.
- Adjust or remove wires if swelling occurs.
- Avoid—stress and heat reduce recovery capacity.
- Use pruning to redirect energy subtly.
- Watch for mites, mildew, and leaf scorch.
- Maintain shade and consistent moisture.
- Delay major work; focus on healing conditions.
- Avoid due to high sap activity.
- Continue semi-hardwood cutting propagation.
- Focus on subtle shape control; avoid stressing the tree.
- Still showy if healthy, but heat stress may affect appearance.

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.
