Black Tower™ Elderberry

Where to Plant

• Sunlight: For the deepest purple-black foliage, plant in full sun with at least 6 hours of direct light daily. While it tolerates partial shade, the leaves will shift toward a dull green and the plant will produce fewer flower clusters.
• Soil: This elderberry thrives in moist, well-drained soil rich in organic matter. If you have heavy clay, mix in several inches of compost to improve drainage, or if your soil is sandy, add peat moss to help hold the moisture these plants crave.

Watering Requirements

During the first growing season, provide 1 to 2 inches of water per week to help the root system expand. Once mature, Black Tower™ is moderately drought-tolerant but will lose its vigor and produce smaller berries if left dry for too long. If you notice the leaves drooping, it is a clear signal that the plant is thirsty and needs a deep soak.

Pruning Tips

Because this variety blooms on new wood, you should prune in late winter or very early spring before new growth starts. Think of it like a seasonal refresh: remove any dead canes and cut the remaining stems back by about a third to encourage a dense, columnar shape. This timing ensures you don't accidentally cut off the buds that produce those signature pink flowers.

Fertilizer Needs

Apply a balanced, slow-release fertilizer in early spring as the new leaves begin to emerge. Avoid using high-nitrogen fertilizers late in the summer, as this encourages soft, tender growth that won't have time to harden off before the first frost. This helps the plant focus on root strength and winter hardiness rather than unnecessary foliage.
