Very strongly acidic soils can be improved by adding dolomite of lime (ground limestone). Very alkaline soils can be improved by watering with slightly acidified rainwater. Add very small amounts of citric acid crystals or one or two drops of hydrochloric acid. Check with a pH meter before use. Alternatively add some horticultural peat (typically pH4) to the mixture,although my prejudice is that peat encourages root meally bugs. Rainwater in or near cities may be naturally acidic. |
