I repotted my Desert Rose about 4-6 weeks ago in succulent soil. I live in central Florida, zone 10a, and she gets full sunshine. I read that she might need phosphorous to help her get to blooming again. Can I use baking POWDER for that supplement? I used Miracle Gro all purpose plant food (liquid) when I repotted her. She is 4 years old.
If you repotted 4 to 6 weeks ago and added fertilizer then, I recommend waiting to fertilize again. I have not heard of using baking powder instead of phosphorus.

Hi - I've already lost one of my beautiful adeniums due to some white powdery substance - all the leaves fell off and none grew in their places. My second one looks like it has the same problem. Is there any thing I can do to save it? See photo Thanks, Carille
Unfortunately, the photo is not very clear. I do see what appears to be a mealy bug infestation. Here are some articles that will help:

I've had one desert rose before and it did not do this. I did not remove any arms, it did this by itself. It flowered once and then decided to take on a live of its very own. It's getting so tall it can't support it's weight by itself!
It may be reaching for the light. Can you give it full sun? If you want it bushier, you can prune it. Here is how:

This rose was seed planted and is about 1 1/2 yrs old. It only grows straight up, but others planted at the same time have grown branches and bloomed. What is the cause?
That's not uncommon. I would cut off the top 1/2 to an inch down. That should cause it to branch.

My rose is very tall, no branches, healthy but only growing tall. If I prune it now would it start putting out branches?
Yes, pruning will help it fill out. Here is how:

I will try to send a photo. I'm older so I don't know if I can do it. I can't get it to down load the picture
The first thing that I would do is have your soil tested. This will reveal any deficiencies that you may have in the area. If the test shows normal nutrient levels, then you may have to look at lighting. It could be that one receives more light than the other, due to shading.
IN the meantime, these articles will help:

I live in Ohio and I'm going on vacation. Will my desert rose seedlings be ok by my southern bedroom window while I'm gone?
You don't say how young the seedlings are or how long you will be gone so it is hard to say. Fall and winter are when they take reduced watering so I think they will be fine, unless they are very tiny. Then they might need some moisture. But if they have a bulb at all there should be stored water.
This article explains their cultural needs so it should help.
