Trimming Mandevilla before bringing it in
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?

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.
