Fertilising a Viburnum tinus
To sustain the vigorous growth and lustrous foliage of Viburnum tinus, a balanced fertilizing regimen is essential. Feed this evergreen shrub in early spring with a general-purpose slow-release fertilizer to support its lengthy flowering period and subsequent fruit development. This initial application will provide a steady supply of nutrients to the plant as it enters its active growing phase.
If the shrub is established and thriving, additional feeding may not be necessary. However, for younger plants or those showing signs of sluggish growth, a second application of fertilizer can be beneficial in late spring or early summer. When applying fertilizer, ensure it is spread evenly around the base of the plant, avoiding direct contact with the foliage and stems to prevent burn. Water thoroughly after fertilizing to help distribute the nutrients into the soil.
