Fertilising a Ilex × meserveae 'Heckenfee'
To ensure vigorous growth and robust health, it is essential to fertilize Ilex × meserveae 'Heckenfee' with an appropriate nutrient mix. A slow-release fertilizer, applied once in early spring, will provide the necessary nutrients to support its development throughout the growing season. The formulation should be balanced, enriching the soil with an even distribution of nitrogen, phosphorus, and potassium, which are vital for the establishment of strong roots and lush foliage. Since > Ilex 'Heckenfee' is evergreen, maintaining an adequate fertilization schedule will also enhance its winter hardiness, helping it withstand temperatures as low as -20.6°C. A second application of fertilizer in mid-summer can further sustain its growth rate and strengthen its visual density.
