This is my first plant ever so please bear with me..My desert rose had green leaves, about 5 flowers and several buds ready to bloom. It gets plenty of full sun. We've been having 90+ degree weather here for the last month and I was watering about once week. About two weeks ago 4 of the 5 flowers had become "soft" and fallen off, followed by all of the buds. Several leaves had turned brown and fallen off as well. I thought maybe I wasn't watering enough so increased to twice a week. The condition of the plant pretty much continued the same. Since I didn't see any change I went back to watering once a week. Now you can see in the pictures that one flower has bloomed along with a lot of growth..buds and new leaves coming in. Some of the leaves coming in are yellow and a lot of the bigger leaves are still turning brown and falling off. Luckily all the new buds are still hanging in there. What could I be doing wrong? There were several more leaves a month ago and it looked much healthier. Do I need to water even less? The soil feels very dry after a few days in this HOT weather.
