Black Beauty Peonies are a stunning and sought-after variety, known for their deep maroon, almost black, double blooms. To grow these peonies, choose a sunny or partially shaded location with fertile, well-draining soil. Plant the peony tubers in the fall or early spring, about 2-3 inches deep and 3-4 feet apart, with the eyes facing upward.
Water the newly planted tubers thoroughly, and continue to water consistently during the growing season. Apply a balanced, slow-release fertilizer in the spring and fall, but avoid applying it too close to the crown to prevent root burn. In the fall, cut back the foliage to ground level and dispose of it to reduce the risk of disease. Mulch the planting area for winter protection, especially in colder climates.
