Gro-Sure Ericaceous Plant Food is perfect for Ericaceous plants such as Rhododendrons, Azaleas and Camellias. It has been formulated with a very low chloride content for feeding all types of acid loving plants. In alkaline and chalk soils, ericaceous plants find it difficult to take up essential nutrients such as iron, and soon become pale and sickly in appearance. The plant food contains iron, magnesium and trace elements, which keep foliage green and healthy. As well as providing essential trace elements, the plant food contains nitrogen, giving the plant a boost each time you feed. It also contains a balance of phosphorus for healthy root growth, as well as increased levels of potassium to enhance flower production, adding vigour and boosting disease resistance.
