Fertilising a Hydrangea macrophylla 'The Original Pink'
To encourage the vibrant, lush blooms of this shrub, regular fertilization is recommended. Apply a balanced, slow-release fertilizer formulated for flowering shrubs in early spring as growth begins. A second application should be made following the initial bloom period, typically in midsummer, to support continued flowering and robust growth. It's important to ensure the soil is well-hydrated prior to fertilizing, as this species requires ample moisture. Over-fertilization can lead to excessive foliage at the expense of blooms, so adhere to the prescribed amounts. Mulching can help retain soil moisture and provide a steady supply of nutrients as organic mulches decompose. Avoid applying fertilizer late in the season, as new growth needs time to harden off before the onset of winter.
