Fertilising a Ligustrum vulgare 'Atrovirens'
To maintain the robustness and enhance the lush green foliage of Ligustrum 'Atrovirens', it is advisable to fertilize this hedge plant annually. The optimal time for fertilizing is in the early spring, just as the growing season commences, which will support its growth rate of 25 - 35 cm per year. A balanced, slow-release fertilizer formulated for shrubs and trees is preferable, as it will provide a steady supply of nutrients throughout the growing season.
Spread the fertilizer evenly around the base of the hedge, taking care not to concentrate it too close to the stems. Water the area well after applying the fertilizer to help distribute the nutrients into the soil. This feeding regimen will assist in establishing a dense hedge capable of withstanding the low temperatures of USDA zone 5b.
