🌱 What Are Amaryllis Bulbs?
Amaryllis are tender bulbs grown indoors in the UK. Each bulb can produce:
- 1–2 flower stems
- 3–6 large blooms per stem
- Flowers lasting several weeks
With correct care, bulbs can be kept and reflowered annually.
🪴 How to Plant Amaryllis Bulbs (Step-by-Step)
1️⃣ Choose the Right Pot
- Select a pot only 2–3 cm wider than the bulb
- Ensure excellent drainage
- Amaryllis prefer snug pots rather than oversized containers
2️⃣ Add Compost
- Fill the pot halfway with free-draining compost
- Do not compact the soil
3️⃣ Position the Bulb
- Place the bulb with roots facing down
- Leave one-third of the bulb above the compost surface
Planting too deeply increases the risk of rot.
4️⃣ Water Lightly
- Water just enough to settle the compost
- Place the pot in a warm, bright spot
Avoid soaking at this stage.
☀️ Light & Temperature Requirements
- Bright, indirect light is ideal
- A sunny windowsill works well
- Ideal temperature: 18–22°C
Excessive heat can cause tall, weak stems.
💧 How to Water Amaryllis Properly
- Water sparingly until growth appears
- Increase watering once flower stems develop
- Allow the compost surface to dry slightly between watering
- Never allow pots to sit in water
Overwatering is the most common cause of failure.
🌸 Feeding & Flowering Care
- Start feeding once leaves appear
- Use a balanced liquid feed every 2–3 weeks
- Rotate the pot regularly to keep stems upright
Blooms typically appear 6–10 weeks after planting.
🌿 What to Do After Flowering
Do not discard the bulb after flowering.
Aftercare Steps:
- Cut off the spent flower stem (not the leaves)
- Continue watering and feeding
- Allow leaves to grow through spring and summer
- Keep the plant in a bright position
The leaves replenish the bulb for future flowering.
🍂 How to Get Amaryllis to Flower Again
- In late summer, gradually stop watering
- Allow leaves to yellow and die back naturally
- Store the bulb in a cool, dry place for 8–10 weeks
- Repot and restart watering
This rest period is essential for reblooming.
