Q. will my desert rose come back after losing all the leaves from aphids or spider mites?

I have had the plant for about a week from the store. I checked the roots – there are no soft spots or discoloration. I noted the webbing after removing the soil and inspecting the plant.

If your plant was healthy to begin with, it has a better chance of bouncing back. Follow the cultural guidelines below and the treatment for spider mites. I think I would visit the store where you purchased the plant because it most likely was already infected when you bought it.

The large one is gorgeous! Desert rose plants should bloom in the same year they are propagated from seed. Check its cultural needs: Five to six hours of sunlight, 1/2 strength fertilizer every week during spring and summer, keep soil moderately moist during growing season - dry side when dormant. If the pots they are growing in are too large, the extra soil will allow too much moisture and the plants will stop blooming.

Q. Why does Desert Rose have a soft globe

I have had my Desert Rose plant for a couple years now and in the last month it has started producing a better leaf and stem. At the same time I have noticed that the root bulb is starting to soften. What would cause this? I have looked on the internet at different sites and found no information about the cause. Should I repot the plant. Change its location. More or less water. Don’t know what would be best to get it back. Can you help me?

Usually a soft caudex means too much water and root rot may be setting in. Try withholding water till the soil is very dry. If things don't improve you can pull the plant up and inspect the roots; if any are dark or mushy, carefully cut those out with disinfected tools. Repot in soil for cactus with additional perlite or sand. See more about their care below.

Q. How Long Should Desert Rose Seed Take To Show?

Seeds do not grow, but seeds from Thailand all came up in 22days.

22 days is on the long end of their germination time. In proper conditions, they should germinate in under a week. You may need to adjust temperature, humidity, or soil moisture in order to achieve proper germination rates.

It could be that the cultivar that is germinating for you is a little more hardy, and will tolerate less than ideal conditions. Since these do germinate in your area, you may want to put your focus into them.

Feeding with most plants should be done before flowering. The best time to feed a desert rose is early in the growing season. Still, you may feed it very sparingly, once per year if you would like. They are not heavy feeders, by any means.

Q. My Desert Rose

I don't understand what's wrong with her. She was fine a week ago and now this. She is on my dining room table so gets morning sun. Too cold to be outside.

Was it by any chance outside during a cold snap? They can't tolerate any temperatures below 40 degrees F. (4 C)
Another possibility is root rot due to improper watering. During the winter, they should be watered very little while dormant. And no fertilizer. If you think that is the case, quickly repot the plant in fresh, dry cactus soil mix.
