Back in October I purchased two Dwarf Cavendish trees from a local greenhouse. They were in tiny pots so I transplanted them into big plastic pots. I also cut off a growth from one of them and potted that also. With being in a 6-7 hardiness zone, I brought them inside before the temps dropped below 40*. On nice days, I set them outside to get good light.
The bigger ones are browning on the edges which I think may be caused by over watering? Should I be backing down on the watering? Should I be trimming the dead leaves? They have grown about 6" in height since I transplanted them.
The little one that was a cutting is growing best. It also sits in a south facing window sill everyday. It was only about 2" when I planted it back in October.
Should I put a UV bulb in the room with them? The room stays about 65-70* on these winter days.
I put pictures in my gallery for reference.
