Growing in Pots, Balconies & Indoors

Euphorbia decaryi is a small, clumping Madagascar succulent the grower keeps indoors with enough light – an easy, characterful houseplant that just needs a bright spot away from cold draughts.

Quick Details

  • Container Size: A pot only 20-50% wider than the root ball – roots stay shallow, so width matters more than depth
  • Indoor Suitability: A good houseplant in good light – keep it away from heaters and air-conditioning
  • Best Spot: Bright light; it prefers about half sun and tolerates more or less
  • Soil & Drainage: Gritty, fast-draining cactus/succulent mix – potting soil with extra perlite, coarse sand or lava grit; never soggy
  • Watering in Pots: Sparing – let the mix dry between waterings; overwatering is the main killer in pots

Indoors & On the Windowsill

  • A good houseplant: The grower keeps this small, clumping succulent indoors with enough light. Give it a bright spot but away from cold draughts, heaters and air-conditioning, which it dislikes. Let the mix dry a little – not fully – between waterings.
  • Overwintering indoors: Most of these are tender – in cold climates a pot lets you bring it into a bright, frost-free room for winter, kept nearly dry until warmth and light return.

On a Balcony or Patio

  • Light & warmth: Give it the brightest, warmest corner – sunny walls and paving throw back the heat these desert plants love. Pots dry faster there, so check the mix, but still water sparingly. Shelter tall or top-heavy stems from strong wind.
  • Practicalities: Use a stable, heavy-based pot for tall specimens, and make sure drainage water runs away freely rather than pooling under the pot.

Choosing the Pot, Soil & Long-Term Care

  • Pot & drainage: A clay pot 20-50% wider than the root ball (roots stay shallow) with strong drainage holes; skip a standing-water saucer to avoid root rot. Terracotta breathes and dries faster than glazed or plastic – ideal for a succulent.
  • Potting mix: A fast-draining cactus mix – potting soil loosened with plenty of perlite, coarse sand or lava grit, with a layer of gravel or small stones at the base.
  • Feeding: Feed lightly – a dilute, low-strength cactus feed once or twice through the warm growing season; nutrients leach from pots faster than open ground.
  • Repotting: Refresh the mix and pot up every few years; these are slow-growing, so they rarely need it more often.
