About Cyclamen

Cyclamen persicum · also called Cyclamen, Persian cyclamen · flowering

Cyclamen persicum is a cool-loving, winter-blooming flowering houseplant with marbled, heart-shaped leaves and upswept petals. It needs bright indirect light, cool rooms, and careful below-pot watering to protect its tuber. The ASPCA lists Cyclamen as toxic to dogs and cats, so keep it out of reach of pets.

Mature size: Compact: miniature types stay under 15 cm (6 in); standard florist cyclamen reach about 20-30 cm (8-12 in) tall and wide.

Watch for — Yellowing leaves: Usually a sign of too much warmth, too little light, or watering errors. Move to a cooler, brighter spot and review your watering. Gradual yellowing in late spring is normal onset of dormancy.

How to tell cyclamen needs repotting

Repotting on a calendar is less reliable than reading the plant. For cyclamen, 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 cyclamen 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 cyclamen

Lift and divide every 3–4 years once clumps congest. Rather than a true repot, cyclamen is lifted and divided once the clump congests and flowering drops off. Tuberous herbaceous perennial grown as a winter-flowering pot plant. It forms a low mound of marbled, heart-shaped leaves with butterfly-like flowers held on upright stems above the foliage. After blooming it goes dormant for 6-8 weeks in late spring to summer, dying back to the tuber before regrowing..

What size pot to step cyclamen up to

Pot size matters less than depth and spacing here. When you replant cyclamen, 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 cyclamen

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 cyclamen in full growth or flower sets it back badly.

Step-by-step: repotting cyclamen

Wait for dormancy. Let cyclamen 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, peat-free potting 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 cyclamen, 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 cyclamen

Cyclamen wants free-draining, peat-free potting mix. Use a light, free-draining houseplant or peat-free multipurpose mix; adding grit or perlite improves drainage. The tuber should sit with its top half exposed above the soil line to reduce rot risk. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting cyclamen — frequently asked questions

How often should you repot cyclamen?

Lift and divide every 3–4 years once clumps congest for cyclamen. Cyclamen 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, peat-free potting mix. Crowding, not pot size, is what reduces flowering over time.

What size pot does cyclamen need?

When is the best time of year to repot cyclamen?

Do you "repot" cyclamen, or lift and divide it?

You lift and divide it. Cyclamen 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 cyclamen after repotting?

Hold off feeding cyclamen 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.
