If planting potted dog rose in your garden, it's best to find a suitable site with adequate sunlight, fertile soil, good drainage, and preferably a place that hasn't been planted with any roses before. A field that previously grew roses may increase the probability of infection. Transplanting can be done in all seasons except winter.
First, dig a pit that is twice as big as the flower pot. Add a small amount of base fertilizer to the pit and place the root system or rootball into the pit so that the root crown (where the aboveground part and the underground part connect) is at or slightly higher than the surface of the soil. Backfill and slowly compact the soil. A layer of organic mulch can be used to cover the soil surface for heat preservation of roots and also reduce the growth of weeds. Water thoroughly after transplanting and water often in the first week to avoid wilting caused by a lack of water.
If transplanting dog rose from one part of the garden to another, do it in fall to avoid the cold of winter. Water the plants three days before transplanting; this makes it easy to dig up and retain the rootballs. Then, trim off the overlong branches and excessive leaves, leaving 3–4 branches per plant to reduce excessive consumption of nutrients and ensure its survival. Prune any unhealthy roots left after being dug up.
If a bare-root rose cannot be immediately planted after purchase, it can simply be placed into a pit and covered with soil. If it has already gone without water for some time, it's better to soak its roots in water for half an hour before planting to help it recover. It is recommended to plant bare-root roses in gardens in the fall.
