Stephanotis is a good porch or houseplant with white summer flowers. This vine is covered with large, oval, glossy green leaves, and grows to 12 feet high.
Mealybugs are small, wingless insects that attack the stephanotis. They use their piercing mouths to suck the sap out of the plant leaves.
Scale insects appear as bumps on the stephanotis leaves. They suck the plant sap until the leaves turn yellow and drop off.
Isolate any stephanotis from other plants if you notice any bug infestation. Use insecticidal soap to wash the bugs off. Encourage natural enemies of the pests, like parasitic wasps and ladybugs, to help keep the unwanted bug population under control.
Sooty mold causes a black surface fungus to grow along the stephanotis stems and leaves. Being weakened by scale insects encourages sooty mold attacks.
Stephanotis can develop root rot when exposed to excessively wet conditions during cool weather.
Stephanotis does not like extreme temperature changes. It needs a constant cool of 55 to 60 degrees Fahrenheit during the winter.
