Alkaline soils have pH readings above pH7.4 and contain relatively more lime. Alkaline soil suits lime-loving (calcicole) plants such as many alpines and many vegetables, especially brassicas (cabbage family). Alkaline soils are harder to make more acid, although the addition of leafmould and sulphate of iron can lower the soil's pH value.

Soil with a pH of more than 6.0 is called alkaline soil.

If you have alkaline soil and prefer a blue hydrangea, see our Planting & Care section for tips.
