Kalanchoe Dying. Kalanchoe sounds like a good choice for your location. Its been perfectly healthy up until this past month.
Over the winter Ive noticed the leaves become limp and papery unlike a plump healthy kalanchoe should be. Take a 2- to 3-inch 5-76 cm section and strip off the bottom couple of leaves. Kalanchoe sounds like a good choice for your location.
It is normal for the flowers to emerge in profusion and then die off.
In fact overwatering is one of the primary reasons for these plants untimely death. When we water plants and the water flows through the soil as the water flows out the bottom it pulls air in behind it from the soil surface allowing the roots to breathe. If the petals remain on the flower clusters after they wilt your variety likely requires deadheading. Water kalanchoe when the soil feels dry just until it feels moist to the touch and avoid wetting the leaves with the water as this can cause bacterial and fungal problems.
