Roses remain a garden favorite. Not only are they beautiful and available in a variety of colors, but they can be mass planted in beds, used as screens or hedges, or planted at fences or trellises and allowed to climb.
In most climates, roses can be planted from early spring to early fall, although spring or early summer is best. This allows roots plenty of time to establish themselves before winter. A more exact planting time is based on whether plants are packaged as bare-root roses or potted roses. Plant bare-root roses in early to mid-spring, after danger of killing frost has passed and before trees and shrubs leaf out. Plant potted roses from spring--after danger of a killing frost--to early fall.
Although early spring is generally the best time to plant roses in cold climates, according to the University of Vermont Extension, you can plant roses in late summer or early autumn as long as you protect them over winter with layers of soil or mulch. In any case, do not plant roses after the first few weeks of fall, as there won't be time for roots to properly develop before spring.
If plants can not be planted as soon as you receive them, prevent their root systems from drying out and keep them in a cool place. Make sure the packing material for bare-root roses is moist.
