I have roses in containers but I need to transfer them into larger pots. I winter them in the house (we live in Alaska) . what I need to know is when to transfer them into the larger pots----when we put them to be or in the spring when we get them up
Growing Roses in Containers
I would wait until they have gone dormant and then move them to the larger pots, it is less stressful on them that way. Water them with some water that has both a product called Super Thrive and a good root sitmulator in it before the transplant and again after. The super thrive helps the rosebushes deal with shock and stress and the root stimulator helps get the root systems growing into their new soils home.
