Fertilising a Lupinus 'Noble Maiden'
To support the vigorous growth and stunning white floral displays of Lupinus 'Noble Maiden', fertilization should be approached with care. Prior to the onset of the flowering months, a balanced, slow-release fertilizer should be applied to ensure that the necessary nutrients are available throughout the blooming period. The application should occur in early spring, as the plant prepares for its growth spurt and again in midsummer to maintain robustness throughout its peak.
While this species is adaptable to various soil types, it is vital to ensure that the soil remains well-drained. Over-fertilization should be avoided as it can lead to excess foliage at the expense of blooms. A moderate approach will satisfy the average nutrient requirements, promoting the upright growth habit and ensuring the plant achieves its full height potential adorned with vibrant flowers.
