Trimming and treating Adeniums in winter
Q: My desert rose below dropped leaves after I replanted it in a bigger pot. I noticed that one of the branches that had been pruned is black at the tip. Please let me know if the section of the branch that turned black needs to be cut. I also wasn't sure how often to water it since the leaves have all dropped. None of the other dessert roses have dropped their leaves but they are all younger plants. Any advice would be much appreciated.
A: Your plant looks healthy and vigorous overall. Dropping leaves
after repotting, or shipping, especially at this time of the year, is normal
in Adeniums. They are deciduous and stay leafless from Fall to Spring.
Some individual specimens can go into dormancy sooner than others - all depends
on conditions: temperature, light, exposure, etc. and individual plant's
"clock".
The black spot on the cut branch may be a sign of a fungus as a result of
excess water.
You may carefully clean/rub it with a paper tower dipped in Hydrogen
Peroxide (pharmacy grade). Then rinse with fresh water.
Keep the plant warm and in a dry spot. Once leaves are dropped, it doesn't
need much water. Once a week watering is enough.
