Do I Prune The Long Tendrils Of My Mandevilla?

Question

I’ve followed your instructions to prepare my Mandevilla for the winter, bringing it indoors and pruning it back by a third. Should I prune the long tendrils as well as the flower bearing stems?

Answer 1

Yes, you can prune the vining shoots, too. You can cut the old shoots or unwieldly shoots back to the ground in late winter, before it starts growing.
