Q.How do I revive a panda succulent?
My husband left my plants outside on our patio, and I live in Texas where it’s real hot in the summer, and now my succulent is dried up from standing in the very hot sun. How can I help my plant get back? One of the flowers already broke off the stem.

Your plant can be moved outdoors in the spring and summer but that hottest sun of the day is probably to much for it!
I would trim away the damaged portion of the plant.
Just give the stressed plant some recovery time in a shaded location.
