I have several tropicals that I've overwintered in the basement and I'm bringing them out of the basement to a sunny room. I have 5 hibiscus where some have a few leaves and some have no leaves. All show green inside the stems when pruned - so I hope that's a good sign. I also have some datura and brugs with a few leaves. Should I start to fertilize right away to encourage new growth? Also, should I cut back the plants. I've been transplanting them into new pots before bring them upstairs. Any suggestions?
