Care
Shrub Rose Care
Best performance in full sun. It is adaptable, however, blooming abundantly when exposed to ample sunlight (6+ hours daily).
Early spring fertilization with a balanced, slow-release fertilizer encourages vibrant growth. Our slow release fertilizer is perfectly suited for this purpose.
Pruning, while not necessary, can promote a more compact growth pattern and should be done in the dormant season to invigorate the plant.
Regular watering during the establishment phase is crucial. Once established, this rose variety shows impressive drought resistance. Mulching helps retain soil moisture and keeps weeds at bay.
Thrives in a variety of soil conditions, as long as the soil is well-drained.
