Fertilising a Hibiscus syriacus 'Pink Giant'
To support the vibrant bloom and robust growth of Hibiscus syriacus 'Pink Giant', it is essential to provide an adequate fertilization regime. Fertilize this deciduous shrub in early spring to kick-start its growth cycle, using a balanced, slow-release fertilizer that can nourish the plant throughout its flowering period. A second application in mid-summer can help sustain its flowering potential through the late season.
It's important to apply the fertilizer at the recommended rate around the base of the shrub, avoiding direct contact with the stems and leaves to prevent burn. Watering thoroughly after fertilizing helps to distribute the nutrients into the soil, ensuring that the roots have access to the essential elements needed for the development of those signature large, pink blossoms.
