🌿 Care Guide
Watering
Water deeply early in the day, wetting the entire root ball; allow soil to barely dry out between waterings.
Fertilizer
Apply a balanced rose or shrub fertilizer in early spring at bud break, again in early summer, and potentially once more in mid-August; stop fertilizing 6-8 weeks before the first frost.
Pruning
Prune in spring as weather warms and buds begin to swell; remove dead wood and thin canes to improve ventilation.
Pests & Diseases
May be susceptible to aphids, rose leafhopper, glasshouse red spider mite, scale insects, caterpillars, and various sawflies.
