I have rooted a rose from a cutting. Being late August do I plant it outside?
Being in Utah I worry about the winter. Should I plant it in a pot and keep it in the house this first winter?
I have better luck planting them outside. Once planted water them in with some water that has both a product called Super Thrive and a root stimulator mixed into the same water. Water them with a fresh batch of the mix the next 5 or so times they need watering and the rose will have its best chance to survive. You could try the potting it up and overwintering inside but such overwintering does require keeping a good eye on watering needs, feeding needs and proper sunlight needs being maintained.
