overwatering and Amaryllis
Quick answer
If overwatering is what's going on with your Amaryllis, the most likely cause is: Forced amaryllis (Hippeastrum) bulbs sit in cool, damp potting mix with no leaves or roots actively pulling water, so any routine watering before green growth breaks the surface keeps the bulb and basal plate saturated; the bulb's fleshy storage scales and the young roots that emerge from them then rot in cold, soggy soil before the plant can push a spike.
Start here:
- 1. Hold the watering can until the first green shoot or roots are visible, then begin watering regularly and keep the soil moist but never soggy, because Amaryllis don't like overwatering and a saturated basal plate will rot before the spike can grow.
- 2. Pot the bulb in a container only an inch or two wider than the bulb all the way around so excess soil cannot stay wet around the roots, and use a well-drained all-purpose potting mix with the top half of the bulb exposed above the soil line.
Why overwatering happens to Amaryllis
Hippeastrum
Forced amaryllis (Hippeastrum) bulbs sit in cool, damp potting mix with no leaves or roots actively pulling water, so any routine watering before green growth breaks the surface keeps the bulb and basal plate saturated; the bulb's fleshy storage scales and the young roots that emerge from them then rot in cold, soggy soil before the plant can push a spike.
How to correct overwatering on Amaryllis
- 1
Hold the watering can until the first green shoot or roots are visible, then begin watering regularly and keep the soil moist but never soggy, because Amaryllis don't like overwatering and a saturated basal plate will rot before the spike can grow.
- 2
Pot the bulb in a container only an inch or two wider than the bulb all the way around so excess soil cannot stay wet around the roots, and use a well-drained all-purpose potting mix with the top half of the bulb exposed above the soil line.
- 3
Stop watering entirely in early fall and let the bulb rest dry for about six weeks in a cool location (40-50F / 4-10C) before re-starting the cycle, since dormant amaryllis bulbs left in damp soil are the classic setup for bulb rot.
Keep overwatering from repeating on this Amaryllis
Always plant amaryllis bulbs with the neck and shoulders above the soil line, pot them only one size up from the bulb, water sparingly until growth appears, then keep the mix moist but not soggy, and give the bulb a fully dry six-week rest in a cool spot each fall before you start the next forcing cycle.
