From deep within Britain's deepest mine in Yorkshire comes this 260 million year old natural fertiliser, full of essential Cations: Potash, Magnesium and Calcium for strong sturdy growth in all plants. Available in its natural state, this Potash granular fertiliser is approved for organic growing by The Soil Association. Apply 'Natural potash, polysulphate' any time from October to May. The standard application rate - in spring - of 20 - 40 gm / m2 will support 3 months growth providing other nutrients are not limiting. Repeat in autumn or winter using heavier doses (up to max 60 gm / m2) to prepare lawns for the following season. Do not apply dry material if drought restricts growth as excessive scorch may result.
