So which type of Kalanchoe did you have on your experiment? I have different types of it and they do have different seasons of active growth.
For example my Kalanchoe delagoensis has more active growth and flowering during warmer weather, and absolutely hates the rain and cold. Then there is Kalanchoe thrysiflora which can tolerate cold showing nice red stressed colors but if you make them wet and cold, it may kill it. It grows actively and nicely during summer. Then there is the other Kalanchoe blossfeldiana which in my area thrives happily during our cold season and rests during warmer season. Kalanchoe tomentosa endures cold, slower growth and goes active again as the warmer weather comes back.
