Cold Frame as Alpine House

[michael z]

Hello,

My intention is to use a cold frame as alpine house, for alpines which are sensitive to moisture during winter. For example, Calceolaria uniflora, Androsacea helvetica,... My plants are in clay pots and my plan is to put the pots into a sand bed. In summertime I could open the frame and in winter I could use it as protection against moisture and very low temperatures.
Has anybody any experience whith an similar setup?

Best Regards,

  Michael

We've  used  a  similar  set-up in the  past, Michael.  Biggest  problem to be  aware  of  is  how  to  keep sufficient  airflow  round the  plants  throughout  the  year.   The  ability  to protect  from extremes  of  temperature  while  keeping off  excess moisture  is  the  main thing  for  you  to tackle.  Good covering  that can be  securely set to remain in position regardless of  wind  conditions is  key.
