Amaryllis Care Guide
Hippeastrum spp.
Quick Answer
Amaryllis 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
Every 7–10 days (growing season)
Winter
None for 8–10 weeks (dormancy needed to rebloom)
Method: Water when top inch is dry; reduce after bloom to trigger dormancy; stop completely for 8–10 weeks
In summer, aim to water amaryllis approximately every 7–10 days (growing season); in winter cut back to around none for 8–10 weeks (dormancy needed to rebloom). Rather than following a calendar, water when the top 1–2 inches of soil feel dry. Water when the top 1–2 inches of soil are dry, then water thoroughly so it drains from the bottom. Yellow leaves often signal overwatering; drooping with dry soil means it needs water now.
Light Requirements
Bright indirect to full sun
Amaryllis does best in a south- or west-facing windowsill where it gets at least 2–4 hours of direct sun. Without direct light, Amaryllis stretches toward the light source, loses its compact shape, and colour or markings may fade.
Soil & Potting
Soil: Well-draining bulb mix or standard potting mix with perlite
Pot: Narrow pot — bulb should fit snugly with only an inch of space on each side; top third of bulb above soil
Temperature & Humidity
Temperature: 50–85°F (10–29°C)
Humidity: Medium (40–60%)
Fertilizing
Frequency: Monthly after bloom until fall
Type: Balanced or high-phosphorus liquid fertilizer to rebuild the bulb
Common Problems
No rebloom
No rebloom: Insufficient dormancy rest. Must have 8–10 weeks dry and cool. Catching the problem early makes it much easier to fix — watch for early warning signs and act before the plant is in serious distress.
Bulb rot at base
Bulb rot at base: Overwatering. Plant shallowly; reduce watering; excellent drainage. Check the roots: if they're dark, mushy, or smell off, root rot has set in. Unpot the plant, trim all affected roots with clean scissors, dust with cinnamon, and repot in fresh dry mix before resuming a cautious watering schedule.
Floppy bloom stalk
Floppy bloom stalk: Normal if very tall; stake with a thin bamboo cane. Catching the problem early makes it much easier to fix — watch for early warning signs and act before the plant is in serious distress.
Mealybugs on bulb scales
Mealybugs on bulb scales: Wipe with isopropyl alcohol at repotting. Check under leaves and along stems regularly, since pests establish colonies before becoming visible from above. Treat with insecticidal soap or neem oil, covering the undersides of leaves, and repeat every 5–7 days for at least three rounds.
Propagation
The most reliable way to propagate Amaryllis is by division at repotting time. Unpot the plant and gently work the root mass apart with your hands or a clean knife, ensuring each section has healthy roots and at least 2–3 leaves. Pot each division into fresh mix and water lightly. The common mistake: being too tentative. It's fine if some roots are disturbed — the plant is resilient once it has its own established root system.
Seasonal Care Calendar
🌸 Spring
Spring is when Amaryllis 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 — Amaryllis 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: Amaryllis 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 winter–spring (timed by when you start the dormancy cycle) — avoid repotting or relocating the plant at this time.
❄️ Winter
In winter, Amaryllis 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.
