So I purchased a bunch of plants from Lowe’s that are in really rough unhealthy shape. I think they have a chance of being nursed back to life. My question is though after pruning all the bad parts out, should I keep the plants in my unheated greenhouse over the winter or bring them inside and keep them in my grow room under the shop lights? They are hydrangeas, spirea bushes and hibiscus. Looking for advice on how I should proceed. Do they need to go through the cold weather process in order to survive? Any suggestions, would be great! Thanks!
