Soil Mix

Repotting

Pruning
Remove old leaves at the base and trim stretched stems in spring if needed.
Pot Preference
A pot with drainage holes; avoid oversized pots that stay wet too long.
Fertilizing
Feed lightly from March to September; use half-strength balanced fertilizer and skip winter feeding.
