Q.hibiscus looks droopy
I brought my hibiscus indoors for the winter, transplanted back outdoors 2 days ago. It did fine indoors but is looking droopy. What can I do to help it?

The droop is a reaction to stress. When moving indoor plants outdoors you need to harden them off. It sounds like maybe your hibiscus was shocked a little from being suddenly exposed to the sun. It’s best to acclimate plants in shadier areas first then gradually introduce them to the sun. Hibiscus, in particular, is a plant that hates abrupt transitions and needs to be hardened off gradually. If you did in fact harden your plant properly then this could just be a matter of transplant shock: https://www.gardeningknowhow.com/plant-problems/environmental/learn-how-to-avoid-and-repair-transplant-shock-in-plants.htm
