Upon receipt, a bare-rooted Rose should be immersed in water for several hours. Never let the plant dry out after soaking and before planting. If planting is to be delayed several days, keep moist (especially the roots) and store in a cool place. If plant ing is to be delayed a week or more, “heel in” the plant, temporarily cov er ing the roots with moist soil or peat. Plant in the spring in a location with at least 6 hours of sunlight per day. Roses are widely tolerant of soils, but happiest in a moisture retentive, well-drained soil slightly on the acid side and enhanced with humus or decayed organic matter.
Space 4 to 10 feet apart, depending on ultimate spread or use. In areas where temperatures drop below 0° F., set so that the bud union (if plants are budded) is 2 inches below ground level; in warmer areas, set so that the union is above or just about at ground level. Meidiland roses are grown on their own roots, and therefore, are not budded. Mound additional soil or compost around canes to a height of 2 inches from the cane ends to prevent moisture loss. When buds start to swell, usually about 7 to 10 days after planting, remove mounded soil or mulch. We recommend a 2-inch year-round mulch over the soil surface. A strong stake is advisable for the taller growing varieties if planted in a location subject to wind.
Many varieties display resistance to pests and disease; however, precautionary mea sures are advisable on a reduced schedule. Fertilize with a standard rose fertilizer after growth has com menced and periodically (as per instructions) up until late summer.
(Fertilizing in the fall can cause soft growth and subject plants to winter injury.) Prune Hybrid Teas, Floribundas, English, and other modern shrub types in early spring before new growth starts, removing any dead, weak or old wood and cutting the plant by 2/3 to 1/2 its length. Taller, more vigorous varieties can be pruned less to allow them to develop an attractive shrub form; however, flowering may be less continuous. Climbers should be pruned in early spring to remove only a few of the older, thicker canes that no longer flower well.
The remaining canes can be lightly pruned for shaping as needed. Old-fashioned types that don’t rebloom should only be pruned in midsummer after flowers fade to remove the older, thicker canes and shorten the remaining canes as needed for shaping.
Winter care for tree roses:
Once the night temperature averages below freezing for 3 to 4 weeks and the plants become dormant, trim the top canes about 5 or 6 inches. In zones 6 & 7, wrap the entire plant with strips of either burlap or stem-wrapping paper (like used on tree trunks). begin wrapping from the bottom of the trunk, overlapping the layers in and around the graft and the stems at the top of the plant, until only the tips are exposed.
In zones 4 & 5, wrap trunk and top as described and then staple a cylinder of tar paper around trunk. Then wrap a larger piece of burlap over the entire top of the rose, tying it tightly to keep it in place. Finally, mound 6 to 8 inches of soil around the base of the plant.
