Fertilising a Matteuccia struthiopteris
To ensure the vigorous growth and lush greenery of Matteuccia struthiopteris, it is important to provide the plant with adequate nutrition. This fern variety thrives in humus-rich soil, which naturally provides many of the nutrients it requires. Nevertheless, supplementing with a balanced, slow-release fertilizer in early spring can promote healthier fronds and enhance the plant's overall vitality.
Apply fertilizer sparingly, as excessive feeding can do more harm than good, especially for ferns which are not heavy feeders. It's best to fertilize at the beginning of the growing season when new fronds are emerging, which allows the plant to utilize the nutrients during its active growth phase. Avoid applying fertilizer late in the season, as this could stimulate new growth that may not harden off before the onset of cold weather.
