Trimming Mandevilla before bringing it in

Question

I have had a Giant Crimson Mandevilla on the deck all summer. It is growing rapidily as cooler nights begin. Can this plant be pruned or should a larger trellis be added to accomadate the new growth when it comes indoors?

Answer 1

You can prune it before bringing it in and the plant will actually be happier if you do. You can cut it back by up to 1/3 before bringing it indoors.
