What to do: Improve the soil structure by adding grit or sand to the planting hole. Ensure your garden bed is slightly raised to encourage water runoff.
Overwatering
PossibleHow to tell: The foliage is drooping and the soil is constantly soggy. You might notice a sour smell coming from the soil.
What to do: Adjust your watering schedule to every 7 to 14 days. Only water when the top inch of soil feels dry to the touch.

When to worry
If the corm is soft and smells bad, it is likely too late to save that specific bulb. Remove it immediately to prevent the rot from spreading to healthy neighbors.
Stopping it coming back
Always plant your crocus in well-draining soil. Avoid watering during the dormant summer months when the bulbs need to stay dry.

Questions people ask
- Can I save a bulb that has started to rot?
- If the rot is very minor, you can try to cut away the mushy part and let the bulb dry in the sun for a day before replanting. However, it is usually safer to discard it.
- How do I know if my soil drains well enough?
- Dig a hole and fill it with water. If it takes more than an hour to drain, you should amend the soil with organic matter or grit before planting.
