I have a few cuttings that I potted 2 months ago. They are growing pretty good. I have not decided where to plant them. Can I leave them in the pots over the winter, or should I plant them on ground ?
Propagating by cuttings is a terrific idea for many varieties of ornamental woody plants, and it’s great that you have had success with rooting your cuttings. Some experts advocate moving the pots into a garage or a cold part of your basement. Another approach is to transplant them now into a sheltered nursery bed in your garden, and, since temperature plays a large role in the survival of young, newly rooted plants, making sure that they are well mulched for protection. Here is some advice given to a previous writer on how to overwinter young shrub cuttings: https://www.torontomastergardeners.ca/askagardener/overwintering-shrub-cuttings/
