This is a lovely succulent but it rots very quickly if too much moisture. One rainy day is all it will take. If more rain is in the forecast, cover it or it will surely die. I don't follow my own advice and have lost it twice, but since it can be found cheaply at the box stores in my area, I gladly buy a new one. After my first loss, I decided to never again provide supplemental water. It did great. Then the rains came and it rotted quickly. Again, withhold supplemental water and cover if more than one rainy day is expected.
