Fertilising a Crataegus laevigata 'Plena'
To sustain the vigor and health of Crataegus laevigata 'Plena', it is prudent to provide it with a balanced fertiliser in the early spring. This initial feeding will support the development of lush green foliage and an abundant display of white blossoms. A slow-release fertiliser is optimal, as it ensures a steady supply of nutrients throughout the growing season, mitigating the risk of rapid nutrient depletion which can occur in well-drained soils.
An additional application of fertiliser can be beneficial in mid-summer, to bolster the shrub as it prepares for the autumn season. During this time, the foliage transforms into stunning shades of red and yellow, a process that can be nutrient-intensive. Utilising a granular or liquid fertiliser that is evenly distributed around the base of the plant, careful to avoid direct contact with the stem, will yield the best results.
