Fertilising a Echinacea purpurea 'Harvest Moon'
To maintain the robust health and enhance the vibrant yellow blooms of Echinacea purpurea 'Harvest Moon', a balanced approach to fertilizing is key. Apply a general-purpose fertilizer early in the growing season to support the vigorous growth and development of the plant. A slow-release formula is ideal, providing a steady supply of nutrients throughout the critical blooming period from July to September.
It is important to follow the recommended application rates on the fertilizer's packaging to prevent overfeeding, which could potentially harm the plant's root system and reduce flowering. Since this species thrives in well-drained soil, ensure that fertilization is coupled with consistent watering to facilitate proper nutrient uptake. Annual fertilization will help sustain the plant's clump-forming and ascending growth habit, reaching an ultimate height of 70 cm with lush green foliage.
