The Westland Ericaceous planting and potting mix are perfect for use with potting and beds and borders all year round. It is a specially blended compost for lime-hating plants such as Azaleas, Rhododendrons and Camellias. It has been blended with Zinc Complex which helps to support a plant\'s health and builds its resilience against pests and disease, therefore providing stronger, healthier blooms. It contains six-month feed for sustained growth and longer-lasting blooms, as well as slow-release iron to maintain an acidic root environment for these acid-loving plants.
