On the Kalanchoe succulent plant, how do you make the blooms last longer? Do you water during bloom time and how far back do you trim the flowering stems after the blooms expire? It's a houseplant.
Yes, you would give the plant water during flowering as you would any other time. You need to water deeply but should let the plant dry between waterings to prevent root rot. Spent flower stems can be cut back to the base of the plant.

I can't get my Kalanchoe plant to bloom. I get beautiful green foliage but no flowers. I tried keeping in a dark place for at least 10 hours a day, but still nothing. My mom has the same plant which blooms beautifully. What am I doing wrong?
Try adding some phosphorus rich fertilizer or bone meal to the soil and see if this helps any.
I'm wondering first what kind of kalanchoe you have. If it's the common one with dark green leaves and flower clusters red, orange,pink, lavender on erect flower spikes, it usually blooms toward the end of the year. Do your mother's plants bloom around that time? if so, in addition to the fertilizer mentioned above, it needs high light, and is actually difficult to get to rebloom. To do so, cut it back to just above the first set of mature leaves, then for 4 months alternate 14 hours total darkness with 10 hours of light, cross fingers and toes and hope for the best. And pump your mom for tips.
They started showing up about a week ago. Then overnight I had every leaf with them and now the leaves are dying.
Without a description of the black spots, I would guess it's an insect, probably aphid, or disease. I suggest taking a sample to your local agricultural extension office for recommendations and identification.

At first I thought I had a chandelier plant but after reading about the mother of thousands, that may be what I have. My plant is about 6 feet tall. It lives in a pot in the greenhouse. I am in zone 9b. My plant started out with one main stem/trunk and many leaves branching out and now all of a sudden the main stem has split into 3 and it is flowering, which I am very excited about. It is so tall though that it is falling over. I want to know the proper time and pruning techniques. If I just hack it off, will it come back?
You can prune it back and it will regrow. You can do so at any time, but some people like to wait until right after blooming to do it.
But, with this plant, if it is floppy and falling over, it may indicate that it is not getting enough light.
How do you get Kalanchoe plants to reflower after first bloom in a pot indoors in a sunny window? How often is it good to apply a light fertilizer?
Try adding some phosphorus rich fertilizer or bone meal to the soil and see if this helps any. These plants can actually be a bit difficult in getting them to rebloom. You can cut it back to just above the first set of mature leaves, then alternate 14 hours total darkness with 10 hours of broght light for a few months.
I read I could start more Kalanchoe with a leaf rooting and I did. But that's all I got, a nice root ball on the end of a leaf stem. What do I need to do to make it start branching?
Give it some more time. Eventually the plant will put up more plantlets from the base of the rooted leaf, but it takes a little while for this to occur.
When I was younger in school, we had these plants which dropped a lot of seeds. They would just fall into the soil and grow more. They had no flowers and didn't need much watering and I had mine for many years. Please help me find out what plant this was!
Sounds like you are describing Mother of Thousands. Might this be your plant?
