About Hairy Sinningia

Sinningia villosa · also called Hairy Sinningia, Hairy Gloxinia · flowering

Sinningia villosa is a tuberous perennial from southern Brazil, distinguished by its densely hairy (villous) stems and leaves, which give the plant a soft, tactile appearance. It produces tubular scarlet to orange flowers over a long season and grows from a compact tuber, going dormant in winter. The most important care rule is to keep the tuber completely dry during its winter dormancy to prevent rot. According to ASPCA guidance on Sinningia (Gloxinia group), this genus is considered non-toxic to cats and dogs.

Mature size: 30–50 cm (12–20 in) tall in flower.

How to tell hairy sinningia needs repotting

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

Flowering has tailed off year on year and the clump has become congested and overcrowded.
Lots of leaf and few flowers — a classic sign that hairy sinningia bulbs or tubers need lifting and dividing.
Bulbs visibly bursting the pot or pushing each other to the surface.
It is the natural dormancy window (foliage yellowed and died back) — the only safe time to lift and split.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot hairy sinningia

Lift and divide every 3–4 years once clumps congest. Rather than a true repot, hairy sinningia is lifted and divided once the clump congests and flowering drops off. Compact tuberous perennial with an upright rosette of velvety leaves; dies back completely to the tuber each winter..

What size pot to step hairy sinningia up to

Pot size matters less than depth and spacing here. When you replant hairy sinningia, set the bulbs or tubers at the correct depth (a rough guide: two to three times their own height of soil over the top) and space them so they are not touching. A wide, shallow pot suits a clump better than a tall narrow one.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot hairy sinningia

The only safe window is dormancy: wait until the foliage has yellowed and died back naturally, lift and divide then, and replant before or at the start of the next growing season. Disturbing hairy sinningia in full growth or flower sets it back badly.

Step-by-step: repotting hairy sinningia

Wait for dormancy. Let hairy sinningia foliage yellow and die back completely. Lifting while it is in growth wastes the energy it is storing for next year.
Lift carefully. Loosen the soil well away from the bulbs/tubers with a fork and ease the whole clump out without spearing them.
Separate the offsets. Gently pull the clump apart into individual bulbs or tubers. Keep only firm, healthy, blemish-free ones.
Replant at the right depth. Reset them in fresh free-draining organic mix at the correct depth and spacing — not touching — so each has room to bulk up.
Water in and rest. Water once to settle them, then keep on the dry side until growth resumes. Do not feed until leaves are actively growing.

Aftercare

After replanting hairy sinningia, keep the soil barely moist — not wet — until shoots appear; bulbs and tubers rot in cold, saturated soil. Once leaves are growing strongly, resume normal watering. Hold off feeding until the plant is in active growth again.

The right soil mix for hairy sinningia

Hairy Sinningia wants free-draining organic mix. Use a blend of peat-free multipurpose compost with added perlite (roughly 2:1) to ensure good drainage and aeration around the tuber. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting hairy sinningia — frequently asked questions

How often should you repot hairy sinningia?

Lift and divide every 3–4 years once clumps congest for hairy sinningia. Hairy Sinningia is lifted and divided, not "repotted". Every 3–4 years, once the foliage has died back and it is dormant, lift the clump, separate the offsets, and replant at the correct depth in free-draining organic mix. Crowding, not pot size, is what reduces flowering over time.

What size pot does hairy sinningia need?

When is the best time of year to repot hairy sinningia?

Do you "repot" hairy sinningia, or lift and divide it?

You lift and divide it. Hairy Sinningia grows from bulbs or tubers, so instead of repotting you wait for dormancy, lift the congested clump, separate the healthy offsets, and replant them at the right depth and spacing. Doing this every 3–4 years restores flowering.

Should you fertilise hairy sinningia after repotting?

Hold off feeding hairy sinningia until it is in active growth again. Fresh soil already carries enough nutrients to get it re-established, and feeding disturbed roots too soon does more harm than good.
