How to plant potted and boxed rose

For Potted Roses

Potted roses are the easiest to plant because you have a plant that is already growing. Potted roses offer the flexibility of being ready for planting throughout the growing season. Potted roses bought early in the season may have most of the soil fall away from the roots when removing the pot. If so, plant as you would a bare root rose. If the potted rose is bought late in the season, the roots may have completely filled the pot and become entangled. If this is the case, be sure to loosen or cut these roots before planting. If you don't, the roots may continue to grow in a circular fashion and never spread out into the garden.

For Boxed Roses

Roses are sometimes offered for sale in cardboard boxes labeled "plant them box and all." Experience shows that this practice often discourages quick rooting and establishment of the plant. There are two options for boxed roses. If the rose is planted in the spring and is still dormant, simply take it out of the box and treat it like a bare-root rose. If the plant has broken dormancy and is growing, cut the bottom off the box and set the rose in the hole at the proper depth. Then, cut through the sides of the box and carefully peel the box away. Refill the hole with soil and water.
