Do not apply lime to acid-loving plants such as camellias, azaleas and rhododendrons. Lime is a white alkaline powdery substance used to correct acid build-up and although it can be used all year round, is popularly used during autumn-winter (Mar – Sep).

Lime can also improve aeration and drainage in clay soils, as it contains calcium which causes clay particles to group together forming soil “crumbs” larger than the soil particles providing easier movement of air, moisture and root development of plants.

Lime is also a useful addition to compost heaps/bins to speed up decomposition.
