How to care for String of Bananas

Curio radicans · Asteraceae

succulenteasy to growtoxic to pets

The forgiving cousin of string of pearls, with glossy banana-shaped leaves on fast-growing trailing stems, formerly Senecio radicans. It tolerates watering mistakes far better and grows quickly enough to recover from setbacks. A great confidence-builder before attempting the fussier trailing succulents. Water roughly every 12 days while it's growing (about every 25 in winter), give it bright, indirect light, kept above 50°F (10°C) — dry air is fine for it.

Care at a glance

Water: every ~12d growing · ~25d dormant
Light: Bright, indirect light
Humidity: dry air is fine — no extra humidity needed
Keep above: 50°F (10°C)
Feed: every ~45d in season
Repot: every ~2 years

Water deeply when the soil is fully dry; the little bananas flatten and dull slightly when the plant wants water.

Bright light with a few hours of gentle sun; it handles a bit more shade than string of pearls without collapsing.

Quarter-strength balanced fertilizer every 4-6 weeks during active growth.

Mistakes that kill this plant

  • Treating its easygoing reputation as license to overwater.
  • Deep, moisture-retentive pots that keep the shallow roots wet.
  • Dark placement, which slowly thins the strands to threads.

Seasonal tips

  • Trim and re-plant cuttings into the top of the pot to keep the crown full.
  • Reduce watering by half in winter and keep it in your brightest window.
  • It grows fast in spring — feed lightly and let it trail or climb along a support.
