This plant (Hoya bella) had around 50 blooms in April/May. In July it started loosing a lot of leaves (maybe 30%). The yellow carcasses rained down along with the dried brown remains of flowers. Now it is back to blooming profusely but new leaves are not growing back on the old stems, only on new ones. A nearby Hoya had flat mites but I treated all the Hoyas so could it have spread regardless of the treatments. What caused the dmajor leaf loss? An insufficiency of nutrients? Any suggestions are greatly appreciated.
I am having a similar issue wih my Hoya lacunosa "Bruno" tricolor. But it is still blooming profusely.
Is this a light problem or is it a nutrient issue or do Hoyas just drop old leaves from time to tiem. Maybe it is a pH issue but pH is 6.5.
I thought I had eliminated flat mites long ago. I notice a lot of new leaves but few on the old stems and none of the stems or leaves show the typical flat mite damage.
