Peggy Martin is hardy in USDA zones 4 to 9 and performs best in full sun with rich, well-draining soil. Like all roses, it wants plenty of light and good air circulation to bloom heavily and stay healthy.
Planting
- Choose a site with at least six hours of direct sun and room for the canes to climb 12 to 15 feet on a sturdy support.
- Work in compost or aged manure to enrich the bed and improve drainage before planting.
- Dig a hole twice as wide as the root ball and deep enough to set the plant at the right level.
- Position the crown (the knob where canes meet roots) at or just below the soil surface, then backfill and firm gently.
- Water in deeply and apply 2 to 3 inches of mulch, keeping it pulled back a few inches from the base of the canes.
Care & maintenance
- Water. Keep the soil evenly moist during the first season, then water deeply about once a week, more in heat. Water at the base to keep foliage dry.
- Feed. Apply a balanced rose fertilizer in early spring as growth begins, then feed again every four to six weeks through summer; stop feeding by late summer so new growth can harden before winter.
- Light. Full sun produces the strongest growth and the heaviest flushes of bloom.
- Prune. Peggy Martin blooms on both old and new wood, so prune in late winter or early spring to shape and remove dead or crowded canes, then tidy lightly through the season. Train and tie young canes onto the support as they grow.
- Mulch & winter care. Maintain a mulch layer to conserve moisture and protect roots; in colder zones, mound extra mulch around the base for winter protection.
- Pests & disease. Watch for aphids, blackspot, and powdery mildew. Good air flow, base watering, and prompt removal of affected leaves go a long way; this rose is noted for its strong overall vigor.
- Bloom tips. Light deadheading of spent clusters tidies the plant and encourages the next flush of flowers.
