The most popular roses grownhybrid teas, grandifloras and floribundasare not fully hardy in northern areas. Short, hot summers and long, cold winters mean that more care is necessary, but these quality roses can be grown in North Dakota.
Choosing a good location for your rose bed is important. Roses should have a minimum of one-half day's sun, but will do better with two-thirds to full sun. A little shade in the heat of the afternoon helps prolong the life of the blooms. Roses should be grown in good garden soils. The addition of organic matter, such as peat or well-rotted manure, will improve the growth and vigor. Choose an area of well-drained soil. Roses won't tolerate wet, soggy soil.
When to plant roses may depend upon whether you buy bareroot dormant bushes or potted plants that are already growing and sometimes even in bloom. Plant dormant bushes early, before trees and shrubs leaf out in the spring or at least by early May. Do not plant growing potted roses that were started in a greenhouse until danger of severe frost is past, late May or early June. When planting dormant, bareroot roses, trim the broken ends of the roots to provide a nice clean cut. Preserve as much of the root system as possible.
How you plant roses is vitally important for winter survival. Dig a hole large enough to hold the entire root system of either potted or bareroot plants without crowding, and deep enough so that the graft (a distinct knobby joint on the stem between the branches and the roots) is 1 1/2 to 2 inches below the soil surface. Planting at this depth is very important in cold climates regardless of other instructions you may have read.
For future reference, you may want to obtain a copy of Extension bulletin H-118 entitled, "Roses for North Dakota", which is available free of charge at your local county extension office.
