Our Tips & Recommendations
Watering
Water deeply twice a week during the first growing season. Once established, roses are moderately drought-tolerant but perform best with consistent moisture at the base.
Pruning
Prune in late winter before new growth begins. Remove dead or crossing branches and shape to an open vase form to improve air circulation and encourage blooms.
Great Companions
Pair with lavender, salvia, or catmint for a stunning cottage garden combination. These companions also help attract pollinators to your roses.
