Soil: Prefers medium moisture, slightly acidic, well-drained garden loam. Roses benefit from the addition of compost, aged manure, or leafmold to the planting soil.
Light: At least 5-6 hours of direct sun per day is preferred, though this variety will grow very well in part shade locations with excellent disease resistance.
Water: One inch of water per week throughout their first growing season. A generous layer of organic mulch (compost or composted manure) helps keep the soil evenly moist. If weather is dry in the fall, be sure to water Roses well. Never allow the foliage to remain wet into the evening; water early in the day.
Spacing: 3 - 4 ft.
Fertilizing: To keep the flowers coming feed your roses with a fertilizer blended especially for roses. This should be done after each bloom cycle.
Winterizing: If you live near a rose's cold limit, and you garden on an exposed site or in an area where rapid temperature fluctuations are common, you should mound two shovelfuls of composted manure, garden soil, compost, or shredded leaves over the base of the plant in late fall after the ground freezes. Covering these mounds and the lower parts of the bushes with evergreen boughs will add protection. Pull the mounding material away from the stem as new growth emerges in spring. Prune branches injured over winter when new buds emerge in spring.
Maintenance & pruning: Cleaning up old foliage is important for disease control. Prune to remove deadwood, to control or direct growth, and to promote flowering. Wait until growth breaks from the canes in early spring before pruning. Every 2 or 3 years remove about one third of the old branches to stimulate new, fresh growth. If you are trying to keep the roses at a certain height, you can cut them back hard with a hedge shears. No need to worry about usual rose pruning rule of cutting back to an outward facing leaf bud; just lop them down to the desired size. There is no need to remove faded flowers, because these roses are self cleaning.
