So, I have this Kalanchoe that got water logged in its original pot without holes. The edges of some of the leaves turned brown. I repotted it and it has been doing well since. I just read that in order for it to bloom through the winter, I need to ensure that it gets 14-16 hours of complete darkness each day from early autumn. So, put it in a cupboard or cover it with a dark cloth each night. Would you recommend I do this now while it still has some flowers? And for the other 8-10 hours do I bring it out to its normal sunny position?

Try to find a light proof cover that you can put over it and leave it in place. A large planter pot, a cardboard box, etc. just be sure it is light proof. Put the cover on and take it off with your natural day length. You're trying to block the plant from ambient light from room lighting. It needs complete darkness during it's dark cycle.

Thank you for that, I'm sure I can find something. It said to start in early autumn, so should I start doing that now do you think or should I look for signs that the plant is starting it's dark cycle? Also, what would happen to plant if this wasn't done, would it just stop blooming?

There is no need to provide darkness while it is still in bloom. Most flowering Kalanchoes sold today are hybrids and often do not require the complete night-time darkness recommended in the past. I'm not sure it is worth the bother. Usually keeping it on a windowsill in a room that gets minimal artificial light after sunset is sufficient to set new buds. Keeping it very potbound and allowing it to dry out more in winter also enhance flowering.

Kalanchoe are photoperiodic plants, along with many others. This means that light cycles affect when these plants bloom. I have read studies of Kalanchoe, Shlumbergia, 'Christmas Cactus', Hatoria, 'Easter Cactus', Rhipsalis, and Rhipsaladosis, where control groups kept in complete darkness for more than 12 hours would bloom after only six weeks when returned to longer light cycles. The other group was subjected to 1 minute of red light during the dark cycle and these plants did not bloom. It didn't make any difference if these were natural cultivars or hybrids. Nurseries and growers, especially now with the better quality artificial lighting, can control these light cycles and force these plants to bloom at any time.

No, you don't need to do this now. I would agree to let it finish it's bloom cycle and have a period of rest before trying to cycle it again. You could have your Kalanchoe go through two bloom cycles per year, just by controlling the light cycle, with no detriment to the plant, providing you let it recover with a vegetative cycle of longer day lengths.

How many plant lovers have purchased a 'Christmas Cactus' covered in blooms around the holidays? In spite of quality care, living for years these plants never bloom again, because their night cycle is interrupted by ambient light. I feel very confidant this is true of your Kalanchoe, whether or not it's a hybrid. I've seen no studies to contraindicate the need for the dark cycle.

@Bigtattoo, thanks so much for the info...you've obviously done your research. I'll give it a go! When you say give it a period of rest before cycling again, do you mean that once it's finished flowering just leave it be for a while and then start the complete darkness cycle? Thanks again!

@Aphria you're welcome, glad to be of assistance. It's important for your plants to go through a vegetative cycle, produce some new leaves and take up nutrients. Your Kalanchoe thinks it's been through a winter dark cycle, it was forced to bloom at this time of year. It's bloomed and now thinks it late spring, early summer when it would naturally grow. You have plenty of time to let it do this. You only need the six weeks of the dark cycle to set it to bloom again. You could do that in early January and stop in late February, early March when your day lengths are getting longer and it will react naturally.

I used to collect and grow many of these plants.

Great, I'll wait til after Christmas so! Thanks again!
