Fertilising a Echinops ritro
To ensure the vigorous growth and striking blue to purple blooms of Echinops ritro, a balanced fertilization regimen is recommended. Begin by enriching the soil with a general-purpose fertilizer in the early spring to kickstart the growth cycle. As this species thrives in well-drained soils and full sun exposure, a second application of fertilizer should be administered during the peak growing months of July and August to sustain its development and flowering potential.
Opt for a slow-release fertilizer that will provide a steady supply of nutrients throughout the growing season, supporting the plant's clump-forming and ascending growth habit. Take care to follow the manufacturer's instructions for the correct dosage to avoid over-fertilization, which can be as detrimental as underfeeding. Properly nourished, Echinops ritro will exhibit robust health and a profusion of its characteristic globular blooms.
