Fertilising a Pennisetum alopecuroides 'Hameln'
To ensure the Pennisetum alopecuroides 'Hameln' thrives, a balanced fertilization regimen is key. Begin by applying a complete, slow-release fertilizer in early spring to kickstart growth. A second application can be beneficial during mid-summer to sustain vigorous foliage and support the production of the plant's distinctive brownish-purple flowers through its blooming months of July to September.
When fertilizing, be sure to distribute the fertilizer evenly around the base of the plant, avoiding direct contact with the foliage to prevent burn. Given its adaptability to various soil types, the 'Hameln' does not require excessive feeding. A moderate approach will supply the necessary nutrients for this ornamental grass to maintain its upright to bushy growth habit and transition into its attractive autumnal yellow foliage.
