1. How to Wake Up Ranunculus Corms Before Planting
Ranunculus corms are small and dry, requiring pre-soaking and rehydration before planting to encourage successful sprouting.
Steps to Wake Up Ranunculus Corms:
-
Soak the corms in water
- Use lukewarm water (~20°C ).
- Soak the corms for 3-4 hours to allow them to absorb moisture and plump up.
- Optionally, add a rooting stimulant or fungicide to prevent fungal infections.
-
Remove from water and dry slightly
- Place the soaked corms on a paper towel for 30 minutes to avoid excessive moisture.
-
Pre-sprouting (optional but recommended)
- Place corms in a moist mix of peat moss, vermiculite, or sand in a container.
- Store in a cool (10-15°C) and dark place for 5-7 days, checking for small root sprouts.

- Cold tolerance: Plants can survive light frosts (-2°C), but cover with frost cloth in colder conditions.
3. Care Tips for Healthy Growth and Prolonged Flowering
Watering:
- Keep soil evenly moist but not waterlogged.
- Increase watering in hot weather but allow the soil to slightly dry between watering sessions.
Fertilizing:
- During early growth: Use a nitrogen-rich fertilizer to encourage foliage development.
- When buds form: Switch to a phosphorus and potassium fertilizer to promote flowering.
Deadheading & Cut Flowers:
- Remove spent flowers regularly to encourage new blooms.
- For cut flowers: Harvest when blooms are partially open, and place in cool water for longer vase life.
After Blooming:
- Once leaves start yellowing, gradually reduce watering.
-
Lifting corms (if needed):
- Dig up corms after foliage dies back (late summer).
- Dry for 5-7 days in a shaded area.
- Store in a dry, cool place (5-10°C) until the next planting season.
