Cyclamen Care Guide
Cyclamen persicum
Quick Answer
Cyclamen is more forgiving than most people expect, but consistent care makes a big difference. Water when the top 1–2 inches of soil are dry rather than on a fixed schedule, give it adequate light for its category, and feed lightly during the growing season. Catching problems early — a change in leaf colour or texture — is the key to keeping it healthy.

Watering
Summer
Almost none (dormant)
Winter
Every 5–7 days when in bloom
Method: Bottom water only; keep leaves and crown dry; water when soil is nearly dry; let drain fully
In summer, aim to water cyclamen approximately almost none (dormant); in winter cut back to around every 5–7 days when in bloom. Rather than following a calendar, water when the top 1–2 inches of soil feel dry. Bottom-watering is ideal — set the pot in a tray of water for 20–30 minutes, then drain any excess from the tray. Yellow leaves often signal overwatering; drooping with dry soil means it needs water now.
Light Requirements
Bright indirect
Cyclamen does best in 2–3 feet from a south- or east-facing window, screened from direct midday sun. A sheer curtain is fine for filtering harsh afternoon sun. Cyclamen adapts to lower light but grows more slowly and the leaves may become smaller.
Soil & Potting
Soil: Well-draining potting mix; good aeration important
Pot: Pot with drainage; don't plant the tuber too deep (top should be at soil surface)
Temperature & Humidity
Temperature: 40–65°F (4–18°C)
Humidity: Medium (40–50%)
Fertilizing
Frequency: Every 2 weeks while in active growth/bloom; skip in dormancy
Type: High-potassium fertilizer (tomato feed) to encourage blooms
Common Problems
Rapid wilting and decline
Rapid wilting and decline: Too warm (above 68°F). Move to the coolest spot in the house. A drooping plant with dry soil is simply thirsty — water it and it should recover within an hour. If the soil is wet and it's drooping, overwatering or root rot is the likely cause; let the soil dry out fully before watering again and check the roots.
Crown rot
Crown rot: Water got into the center crown. Switch to strict bottom-watering only. Catching the problem early makes it much easier to fix — watch for early warning signs and act before the plant is in serious distress.
Botrytis (gray mold)
Botrytis (gray mold): Poor airflow + humidity. Remove affected leaves; increase air circulation. Catching the problem early makes it much easier to fix — watch for early warning signs and act before the plant is in serious distress.
Won't rebloom
Won't rebloom: Needs dormancy rest in summer + cool conditions in fall. Catching the problem early makes it much easier to fix — watch for early warning signs and act before the plant is in serious distress.
Propagation
Cyclamen is typically propagated by seeds (slow, requires cold stratification), tuber division (risky). Work during the active growing season (spring or early summer) for the best success rate. Keep propagations warm, humid, and in bright indirect light while they establish. Resist tugging on them to test for roots — a gentle resistance when you lightly pull is enough to confirm they've taken.
Seasonal Care Calendar
🌸 Spring
Spring is when Cyclamen starts actively pushing new growth as day length and light intensity increase. Increase watering frequency as the plant becomes more active, begin fertilising every 2–4 weeks with a balanced liquid fertiliser, and this is the ideal window for repotting or taking cuttings.
☀️ Summer
Summer is peak growing season — Cyclamen is working hard and using water and nutrients faster than at other times of year. Water more frequently but check the soil rather than going on a fixed schedule, since heat and higher light accelerate drying. If you move it outdoors, introduce it to conditions gradually to prevent sun scorch.
🍂 Fall
Fall is a transition: Cyclamen grows more slowly as light levels decrease. Reduce watering frequency slightly, stop fertilising by late October, and move it closer to a window to compensate for shorter days. Avoid drafts from opening windows as temperatures drop. Watch for flower buds developing around fall through spring (cool-season bloomer) — avoid repotting or relocating the plant at this time.
❄️ Winter
In winter, Cyclamen enters a slower-growth phase and uses water more slowly than in summer. Water less frequently to avoid root issues from soil staying wet too long in low light. If your home is heated and the air is dry, a pebble tray or humidifier keeps the plant comfortable.
