Fertilising a Hosta fortunei 'Aureomarginata'
To maintain the striking variegated foliage of this species, it is essential to provide adequate nutrition through appropriate fertilization. A balanced, slow-release granular fertilizer applied in the spring can promote a vigorous start to the growing season. Another application during the early summer months can further sustain its development, ensuring the leaves retain their vibrant green and yellow margins.
For optimal growth, it is recommended to fertilize the plant twice a year, ideally when the risk of frost has passed and the soil has warmed. This timing allows the roots to efficiently absorb the nutrients as the plant enters its active growth phase. Ensuring the soil is well-drained will also help prevent nutrient leaching, allowing the plant to fully benefit from the fertilizer applied.
