Cold Damage to Cactus
I have a very six foot tall cactus (Euphorbia Tree) that normally thrives in our sunroom. We had several very cold days and it got much too cold in that non-insulated room. All of the new growth on the cactus has either shriveled or turned light greenish-yellow and is droopy. What can I do to revive it?
If the damaged areas continue to deteriorate or show no signs of improvement it is time to do some pruning. Remove the dead portions back to a healthy stem. If older parts of the plant are firm and normal color there is a good chance the plant will survive and eventually produce new growth. Prevent future cold damage and continue to give it proper care and time to recover.
