rot following probable cold damage.
Default rot following probable cold damage.

So, I went on holiday after Christmas for 2 weeks, and something clearly went very wrong with my heating system. My warm-growers are almost all (exceptions being 2 hardy NOID phals) showing signs of cold damage to varying degrees. Worst affected are Ludisia discolor (rot set in stem, cut and removed infected area) and Bulbophyllum Jersey (have lost 18 months growth on a young plant). Other than keeping warm, is there anything the collective wisdom of the orchidboard can suggest to help recovery? I also have a paph and 3 further phals showing stressed signs (blackened buds) but am not so concerned about them as for the Ludisia and Bulbo.
Thanks.
Kay

I would agree with Dounoharm. Pics as Philip has suggested would help us give more detailed advice.

In order to avoid fungal infections, I pretreat in fall with strong antifungals (mixture of dithane and thiomyl) then repeat in 3 months (so Sept and Dec). Then, I back off on watering unless absolutely necessary when it is in the 50's or lower. Vandas are not happy with this and are dropping some of their leaves. Since the catts get the rot the easiest, I really need to keep them drier and that dictates the amount of watering everyone in the greenhouse gets. (I have too many plants to individually water them.) No rot this year! But I have learned the hard way. I lost about 20 catts two winters ago to black rot.
