Gardening Cuttings: Tonic sulphur

Click to follow
GREENACRES, of PO Box 1228, Iver, Buckinghamshire SL0 0EH, specialises in introducing to the amateur products that professional and commercial growers have been using for a long time. One of its latest introductions is sulphur chips, which can reduce the pH level of soil and make it more suitable for acid-loving shrubs such as camellias and rhododendrons. I believe you should garden with the flow rather than fight against it, but those who cannot live without a rhododendron should contact Greenacres (0895 835235). A 125g bag costs pounds 2.25.
