Fertilising a Deschampsia cespitosa
For optimal growth, Deschampsia cespitosa benefits from regular fertilization. Providing nutrients during the active growing season supports the development of its distinctive, airy inflorescences and maintains the lush greenery of its foliage. Apply a balanced, slow-release fertilizer in early spring as new growth appears, ensuring that the granules are spread evenly around the base of the clump, avoiding direct contact with the foliage to prevent burn.
A second application may be made after the initial flowering period in late summer to promote continued vigor and prepare the plant for the following year. Since Deschampsia cespitosa is not evergreen, the second fertilization helps strengthen the plant before it goes dormant. Water the area gently after fertilizing to help integrate the nutrients into the soil.
