Powder Puff Bonsai Care
Calliandra
The powder puff (Calliandra) is a spectacular flowering bonsai whose blooms are fluffy silky pom-poms of red or pink stamens over ferny leaves that fold at night - a warmth-loving tropical for a bright, frost-free spot.
Few flowering bonsai stop people in their tracks like a powder puff in bloom: its flowers are soft, silky pom-poms of scarlet or pink stamens, scattered across a canopy of fine, feathery leaves that fold closed at dusk. A warmth-loving tropical from the Americas, it rewards bright light and steady moisture with repeated flushes of those extraordinary puffs. Give it warmth and sun and it flowers with abandon.
Overview
A tropical flowering shrub with silky red or pink powder-puff blooms and fine feathery, night-folding leaves. Spectacular in flower; warmth- and light-loving, and grown mainly for those puffs.
Light & position
As much bright light and sun as you can give - a hot, sunny windowsill or conservatory, or outdoors in warm weather. Strong light is essential for good flowering.
Watering
Keep the soil evenly moist through the growing season - it is a thirsty tropical - watering when the surface begins to dry. Reduce a little in winter, but never let it dry out hard.
Pruning & shaping
Trim after each flush of flowers to shape and prompt the next; it is vigorous and back-buds well. Its naturally spreading, flat-topped habit suits informal and umbrella styles.
Wiring
Young shoots wire well; the fast growth means wire can bite quickly, so check often. Much shaping is also done by pruning.
Repotting & soil
Repot every 1-2 years in spring into free-draining bonsai soil, trimming roots. It recovers strongly in warmth.
Feeding
Feed regularly through the growing season, favouring a flowering feed to support the abundant blooms; ease off in winter.
Winter & seasonal care
Frost-tender: winter it indoors above about 12°C, bright; outdoors year-round only where frost-free. Some leaf drop in a cool, dim winter is normal.
Common problems & pests
Failure to flower is usually too little light. Spider mite and aphids can attack soft growth. Root rot from soggy soil, and cold damage, are the main dangers.
FAQ
Why do the leaves close up in the evening? Calliandra leaves fold at night (nyctinasty) - a normal, charming habit, not distress.
Why won't it flower? Usually not enough light - give it the brightest, sunniest spot you have.
⚠️ Bonsai tools and training wire are sharp - keep them away from children. Some bonsai species (and their sap, leaves or seeds) are toxic to pets if chewed; check before keeping one where animals reach. This is general growing guidance; specifics vary by climate and individual tree.
