I transplanted a 3 year old giant bird of paradise from a semi low light corner in my living room to outside. We divided and then replanted outside in a large planter. It's been about 2 months and a few leaves died immediately. A couple of the leaves have sunburn, but there are a couple of new leaves that have survived. I know that I need to trim the sunburned leaves off, but am scared that the plants will die, as there will only be 2 new baby leaves that have not grown at all since the transplant. How do I save these plants? I moved them outside, as they were looking very sad after being in that corner for 3 years.
