Are you wanting to know how to transplant a rose bush from outside in the dirt into a pot?
Hi Suzanne, Tall containers are a good choice for patio roses since rose roots grow deep. If your container doesn't have drainage holes, make a few in the bottom. Place a small piece of window screen or mesh, or a few pieces of broken pottery, over the holes, so the soil doesn't wash out when you water.
Be aware if you live where the ground freezes, the rose bush may not make it to a 2nd season. When they are in the ground, their roots are protected. In a pot the entire pot may freeze. Tea roses are often grafted onto another root, so even in the ground, these require mulching over the grafted portion to increases their chance of survivable thru a cold winter.
