Fertilising a Cornus alba 'Sibirica'
For optimal growth and development, it is essential to provide the shrub with a balanced fertilization regime. Fertilize this species in the early spring as new growth commences and again in mid-summer to support continued vitality. A slow-release, granular fertilizer formulated for deciduous shrubs is ideal, as it ensures a steady supply of nutrients over several months. Distribute the fertilizer evenly around the base of the plant, extending out to the drip line, and water thoroughly to help the nutrients penetrate the soil.
By adhering to this fertilizing schedule, the plant will be better equipped to produce its characteristic bright red stems and lush green foliage, which transforms to a striking red in autumn, as well as its white spring flowers and autumnal fruit. Regular fertilization also strengthens the plant's overall health, enabling it to withstand the rigors of the growing season.
