Vitax Garden Lime, supplied in a virtually dust-free granular form, is an excellent conditioner for all types of soil and is also an important source for added calcium and magnesium. It improves the drainage of heavy clay soils, making them more friable and easier to work. It can also be used as an Autumn top dressing on lawns. Vitax Garden Lime can be applied to acid soils on an annual basis after September and to normal soils every two to three years. It can also be added to compost when specified in the mix.
