I thought it was dead after fire in cold weather, no place to put it; but it came back. I transplanted seeds from last summer have gotten one to start (germinate) but do not know how to keep it from becoming dormant. After two weeks, it seems ok but still need to know how to take care of it. . . direct sun, how much water, etc.

The plant is flowering but the leaves are yellowing?
There are several causes for yellowing foliage, but the number one reason is stress-underwatering, nutrient deficiency, shock, pests, etc. Pinpointing the cause for this stress is important in treating the plant.

Desert rose is losing leaves. Do I need to repot it? I try not to over water it. I just need to know how to care for it.
Could be it is time to repot it and also make sure it is getting plenty of sunlight. They do tend to drop older foliage as new foliage comes in, kind of the cycle of life thing for them. It sounds like you are watching the watering which can cause such problems. Also be sure the pot you plant it in has a drainage hole or drainage holes. Also when watering it, do not let it sit in the bottom saucer full of water for more than a half hour. Letting it sit in a saucer full of water will cause root problems the same as overwatering does.
I have a desert rose that has bloomed great. It has a long tubular pod at the end.
Here is a link to a website with more information for you. Congratulations to you too! You have a seed pod formed up!! Nice!!

My desert rose has two seed pods. When should they be removed if I want to make more flowers?
Usually once they're dry on the plant, you can remove them. This article may also help: https://www.gardeningknowhow.com/ornamental/flowers/fgen/harvesting-garden-seeds.htm
I would like to graft different color flowers on one desert rose plant. What is the best method of achieving that?
My desert rose is a bonsai but does not branch. Can I force it to? It is 12 months old and 15cm (6") high.
If the plant is only 6" tall, it is still considered a seedling. It will branch as it ages.
