Nhu, those are our spring temperatures, winter was cooler. Several times going below 0ºC. The ones in the garden are under the fruit trees (bare in winter) which is in a bark garden. Rot has never been a problem. Any in the garden come up faithfully the following season. I do find the birds love to scratch them out of the soil so some of the bulbs may be getting more air than was bargained for. The ones in the garden seem to survive our wet winters. However, the soil is volcanic and has wonderful drainage.
