🌺 Amaryllis Care (UK Guide): Watering, Feeding, Repotting & Reblooming
🌺 Introduction: How to Keep Amaryllis Thriving Year After Year
Amaryllis are among the most dramatic winter-flowering houseplants, producing bold, trumpet-shaped blooms when little else is in colour. With the right care, amaryllis bulbs can be kept for many years and rebloom reliably. The key is understanding their watering needs, feeding routine, repotting timing, and essential rest period.
This UK-focused guide explains exactly how to care for amaryllis from first growth to reblooming success.

💧 How to Water Amaryllis Correctly
Watering is the most important part of amaryllis care.
🌱 Before Growth Appears
- Water very sparingly
- Just enough to stop compost drying out completely
- Too much water at this stage causes bulb rot
🌿 During Active Growth & Flowering
- Increase watering once leaves or flower stems appear
- Allow the top few centimetres of compost to dry between watering
- Water around the bulb, not directly onto it
Never leave pots standing in water.
🍂 After Flowering
- Continue watering while leaves are green
- Leaves are essential for recharging the bulb
💤 During Dormancy
- Stop watering completely
- Keep the bulb dry during its rest period
🌱 Feeding Amaryllis: When & How Often
🌸 When to Start Feeding
- Begin feeding once leaves appear
- Do not feed dormant bulbs
🌿 Feeding Schedule
- Feed every 2–3 weeks
- Use a balanced liquid feed during leaf growth
- Switch to a high-potash feed in late spring and summer
This helps the bulb store energy for next year’s flowers.
🪴 Repotting Amaryllis Bulbs
Amaryllis like to be slightly pot-bound.
🕰️ When to Repot
- Every 2–3 years
- Best time: after dormancy, before watering restarts
🪴 How to Repot
- Choose a pot only 2–3 cm wider than the bulb
- Use fresh, free-draining compost
- Replant with one-third of the bulb above soil level
- Water lightly after repotting
Oversized pots encourage leaf growth but fewer flowers.
🔁 How to Get Amaryllis to Rebloom
Reblooming requires a proper rest period.
🍃 Step 1: After Flowering
- Cut off flower stems only
- Keep leaves intact
- Continue watering and feeding through spring and summer
🍂 Step 2: Start Dormancy (Late Summer)
- Gradually reduce watering
- Allow leaves to yellow and die back naturally
💤 Step 3: Rest Period
- Store the bulb in a cool, dry place
- Ideal temperature: 10–13°C
- Rest for 8–10 weeks
No light or water is needed during this time.
🌱 Step 4: Restart Growth
- Repot if needed
- Move to a warm, bright location
- Begin watering lightly
Flowers usually appear 6–10 weeks later.
☀️ Light & Temperature Requirements
- Bright, indirect light is ideal
- A sunny windowsill works well
- Ideal growing temperature: 18–22°C
- Too much heat causes tall, weak stems
Rotate pots regularly to keep stems upright.
⚠️ Common Amaryllis Problems & Fixes
Leaves but no flowers
- Bulb skipped dormancy
- Insufficient feeding
Bulb rotting
- Overwatering
- Poor drainage
Floppy stems
- Too warm
- Low light
Yellow leaves early
- Overwatering
- Natural end of growth cycle
❓ Frequently Asked Questions
How often should I water amaryllis?
Only when compost begins to dry — never on a fixed schedule.
Can I keep amaryllis outdoors in summer?
Yes, in a warm, sheltered spot once frost risk has passed.
Do amaryllis need misting?
No — misting increases disease risk.
Are amaryllis toxic to pets?
Yes — keep bulbs and leaves away from cats and dogs.
🧠 Key Takeaway
Amaryllis care is all about balance and timing. Water sparingly, feed consistently during leaf growth, allow a proper dry rest period, and avoid overpotting. Follow this cycle and your amaryllis will reward you with spectacular blooms year after year, making it one of the most satisfying winter houseplants to grow in the UK.
