Last year I overwintered >220 pots of EE; ~ 50 varieties.
With all the pests (aphids and spider mites) and dealing with differing watering needs, I am looking to other methods for overwintering.
I have Colocasia, Xanthosoma and Alocasias.
1. I know some of the Alocasias need to be overwintered as plants. Are there any Colocasias or Xanths that also need to be overwintered as plants?
2. Is it better to overwinter EE in pots or as bare corms?
3. I don't have a basement and my garage can get down to 32F (I have successfully overwintered Peruvian Daffodils and Amaryllis as bare bulbs in the garage for several years. But last year I lost all EE I tried to overwinter in pots in the garage except Pink China and Fontanesii).
So, can I overwinter bulbs in a refrigerator at 5C (~40F) or can I buy a refrigerator and set the temp to 10C (50F)?
4. Is there a minimum size for a corm to successfully overwinter?
5. Other options?
6. For overwintering in a GH, what is the ideal temp? Last year I kept it about 75F high/65 low but the plants seemed to exhaust themselves like they were trying to grow but had too little light and too much heat to go dormant.
Thanks, ROX
