The best time to move your hybrid tea roses is in early spring while they are still dormant. If you live in a cold climate, do this as soon as the ground thaws in late winter or early spring. Prepare new planting holes before you dig the roses. Then dig each rose, keeping a large ball of soil around the roots if possible. Use a sharp spade to slice through the soil and roots; clean cuts will seal over more rapidly. If the plant is still dormant, you can also have success transplanting by digging the plant bare-root. Again, use a sharp spade to dig the plant, and avoid tearing the roots as you pry the plant out of the ground. If you move the plant without disturbing its roots, the plant will suffer less shock in the transplant. Mulch around the rose after you plant it, and keep the root system moist but not soggy throughout the first growing season after transplanting.
