About Stapelia hirsuta

Stapelia hirsuta · also called hairy stapelia, shaggy stapelia · houseplant

Stapelia hirsuta, the hairy or shaggy stapelia, is a South African stem succulent famous for large, velvety, banded red-and-yellow star flowers fringed with long purple hairs that mimic rotting meat to attract fly pollinators. Its soft four-angled stems clump steadily. Grow it as a desert succulent with bright light, sharp drainage, and a dry winter rest.

Mature size: Stems reach about 10-20 cm (4-8 in) tall, spreading to 30 cm (12 in) or more; the hairy flowers are typically 7-12 cm across.

Watch for — Stem rot: Mushy, blackening stems from overwatering or cold-damp soil. Excise rotted tissue, let cuts callus, and re-root sound stem pieces in dry gritty mix.

How to tell stapelia hirsuta needs repotting

Repotting on a calendar is less reliable than reading the plant. For stapelia hirsuta, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot stapelia hirsuta

Every 2–3 years, into bone-dry mix. Stapelia hirsuta's growth habit — clump-forming succulent with erect, soft, four-angled, finely toothed and slightly downy stems that branch from the base into broad mats. — sets the pace.

What size pot to step stapelia hirsuta up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Stapelia hirsuta stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot stapelia hirsuta

Spring or summer, while stapelia hirsuta is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting stapelia hirsuta

Repot dry. Do not water stapelia hirsuta for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty free-draining cactus and succulent mix ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set stapelia hirsuta at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep stapelia hirsuta completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for stapelia hirsuta

Stapelia hirsuta wants free-draining cactus and succulent mix. Plant in gritty, fast-draining compost, ideally cactus mix cut with perlite, pumice, or coarse sand. A wide, shallow pot with good drainage matches the spreading, shallow roots; avoid dense, moisture-holding potting soil. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting stapelia hirsuta — frequently asked questions

How often should you repot stapelia hirsuta?

Every 2–3 years, into bone-dry mix for stapelia hirsuta. Repot stapelia hirsuta every 2–3 years into a snug pot of free-draining cactus and succulent mix, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does stapelia hirsuta need?

When is the best time of year to repot stapelia hirsuta?

Should you water stapelia hirsuta after repotting?

No — not straight away. Repot stapelia hirsuta into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise stapelia hirsuta after repotting?

Not immediately. Wait about 3 weeks after repotting stapelia hirsuta. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
