My husband bought me a desert rose about a month ago with tons of beautiful pink blooms all over it. We put it in a bright sunny place , fertilized it lightly and didn't water it too much for fear of rot and it did well. Now the blooms have all fallen off and I am left with green healthy looking leaves. Is this normal ?? Is it just going dormant?? Should I stop watering it completely or have I done something wrong?? Any info would be greatly appreciated, I really fell in love with this plant.
