About Spring Cyclamen

Cyclamen coum · also called Eastern Cyclamen · flowering

Spring cyclamen is a compact, winter-to-early-spring flowering tuber with rounded, often silver-patterned leaves and squat magenta, pink or white blooms. Fully hardy, it carpets shady borders and woodland edges when little else flowers. Summer-dormant, it needs a dry rest. Smaller and earlier than its autumn-flowering ivy-leaved cousin.

Plant type: flowering

Watch for — Botrytis (grey mould): Grey fuzzy mould on foliage in cold, damp, still air. Remove spent flowers and dead leaves and improve ventilation.

The reasons spring cyclamen isn't blooming

Almost every non-blooming spring cyclamen traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding spring cyclamen a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get spring cyclamen to flower

Maximise sun. Give spring cyclamen the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for spring cyclamen and get the feeding right with the spring cyclamen fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Spring Cyclamen flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

For everything else this plant needs day to day, see the full spring cyclamen care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Spring Cyclamen blooming — frequently asked questions

Why won't my spring cyclamen flower?

Spring Cyclamen blooms on the season's growth given enough sun, warmth and the right feed — there is no cold or photoperiod trick, just good growing conditions and a bloom-leaning feed. The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.

How do I make spring cyclamen bloom?

Give spring cyclamen the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
