Ericaceous compost is a type of compost that is more acidic than regular compost, with a pH of between four and five. It is named after the "ericaceae" family of plants that like to grow in it, which includes acid-loving or lime-hating plants such as rhododendrons, azaleas, camellias, pieris, blueberries, heathers, and other plants that dislike alkaline soil. Ericaceous compost is suitable for growing these plants because they need a more acidic soil to thrive, and they find it difficult to take up nutrients in non-acidic alkaline soil that has a pH value above 6.
Ericaceous compost can be bought from garden centers, nurseries, retail DIY stores, and direct from the manufacturer by mail order. There are also a few peat-free ericaceous composts available, with ingredients such as composted bracken or bark, coir (coconut fiber), and wool. To make ericaceous compost, you can use high-acid organic matter such as oak leaves, pine needles, or coffee grounds, and avoid adding lime.
In summary, ericaceous compost is a type of compost that is more acidic than regular compost, suitable for growing acid-loving or lime-hating plants such as rhododendrons, azaleas, camellias, pieris, blueberries, heathers, and other plants that dislike alkaline soil. It can be bought from garden centers, nurseries, retail DIY stores, and direct from the manufacturer by mail order, or made by using high-acid organic matter and avoiding adding lime.
