Our azalea, rhododendron and shrub feed is ready-to-use fertiliser specially formulated for acid-loving plants to help them thrive in both neutral and acid soils, giving bigger blooms, greener leaves and robust plants. It is an organic-based feed with added iron for azaleas, rhododendrons and shrubs, including acid-loving plants such as heathers, conifers, magnolia, skimmia, camellia, berberis, hydrangea, raspberry and pernettya. It contains fast-acting iron for strong growth and rich green foliage, which helps prevent leaf yellowing (chlorosis). Apply directly onto the soil during the growing season (March to September).
