Thank you for contacting Toronto Master Gardeners:
The above photo did not have a question. Looking at the pot, the plant seems to have been overwatered. Kalanchoes do not like wet soil, and during the winter months indoors, it is best to let the plant dry out between watering.
It is also affected by aphids, mites, scale and mealybugs. The plant can be saved from the attack of insect pests by rubbing the leaves and stems with 70% isopropyl alcohol, or nontoxic insecticidal spray will also keep the insects away.
