Fertilising a Heuchera sanguinea 'Leuchtkäfer'
For optimal vitality and a vibrant display of red blooms, Heuchera sanguinea 'Leuchtkäfer' benefits from regular fertilization. This cultivar thrives with an application of a balanced, slow-release fertilizer in early spring, as new growth commences. A second application should be considered in mid-summer to sustain the plant's vigor and support its clump-forming growth habit throughout the flowering months.
Select a fertilizer formulated for perennial plants and follow the recommended dosage to prevent overfeeding, which can lead to excessive foliage at the expense of blooms. Well-drained soil assists in the efficient uptake of nutrients, ensuring that the 'Leuchtkäfer' maintains its lustrous green foliage and fragrant red flowers. Always water the plant after fertilizing to help distribute the nutrients around the root zone.
