Q.New Guinea Impatiens
Hi
I have many of these in my garden and would like to see if I can get them through the winter in my greenhouse. They will be lifted and potted up but should they be left as is or cut back and if so by how much.
Many thanks

You can dig them up and replant them, and most likely they will survive. I would consider removing any blooms as this will interfere with root production. You can even start new plants from tip cutting. Here is an article for more information: https://www.gardeningknowhow.com/ornamental/flowers/impatiens/impatiens-rooting.htm
