I've had these Arums for a number of years. A. palaestinum, A. korolkowii and an Arum I was given by a colleague in Puglia, Italy. The soil has been changed and pots sterilized more than once. I feed with an organic fertilizer Down to Earth which is a blend of organic components. I have them under some T-5 LED lights in a cool greenhouse not below 45-50 F. Any suggestions would be most appreciated as to how to correct this condition. This has occurred for 3-5 years. The initiate growth and around this time of year the leaf wilt appears. Thanks in advance.Arnold New Jersey -------------- next part -------------- A non-text attachment was scrubbed...
