Fertilising a Sambucus nigra 'Black Lace'
To ensure the Sambucus nigra 'Black Lace' thrives, a balanced approach to fertilization is key. Begin in early spring, applying a general-purpose fertilizer formulated for shrubs. This initial feeding supports the vigorous growth and development of the stunning purple foliage and the delightful flowers that bloom in May and June. A second application of fertilizer is recommended in mid-summer to sustain the plant's energy as it enters the fruiting phase, yielding the characteristic black and purple berries by autumn.
Avoid over-fertilizing, as excessive nutrients can lead to foliage at the expense of flowers and fruits. It's best to follow the recommended rates on the fertilizer packaging. Water the shrub well after applying fertilizer to help distribute the nutrients evenly throughout the soil.
