- General Plant Care: Even low-maintenance roses should be monitored for pests, such as aphids, and diseases, such as black spot. A systemic rose care product used according to package directions may help address issues. Watering at soil level instead of on leaves and maintaining good air flow around the plant may also help prevent problems.
- General Planting Tips: Container-grown roses can be planted at any time, but bare-root plants should be planted while dormant, in fall through early spring. Dig a hole as deep and twice as wide as the container or root system. Plant roses in containers as you would any shrub. For bare-root roses, build up a cone of soil in the center of the planting hole. Soak the roots well in water, then place on the cone with the roots fanning around from the base. Backfill with soil and water well. Add additional soil if needed to keep level with surrounding soil. Mulch with 2-3 inches of organic mulch, keeping away from trunk of plant.
- General Fertilizing Tips: Roses are heavy feeders, and do best with multiple applications of fertilizer specifically formulated for roses several times per year, according to package directions.
- General Pruning suggestions: Roses should be pruned in late winter, just before spring leaf growth begins. Roses are vigorous growers, and respond well to heavy pruning. Remove any old, weak, diseased, or crossing canes by cutting back to the ground, leaving only 3-4 of the most vigorous, younger canes. Prune those canes to be 12-18 inches tall, cutting just above a leaf bud facing to the outside of the plant. Most roses rebloom best when faded flowers are cut back after blooming.
- Bloom Tips: Remove flower stalks after blooms have faded
