We recommend using a soil pH Test before using Garden Lime. You can apply Garden Lime all year but we recommend to use in Autumn before frost. Ideal pH value is between 6 and 7. Do not apply around ericaceous plants and vegetables. For normal soils add every two to three years, highly acidic soils will need an annual application. Young Plants - Dig into planting hole for best results. Use 1 handful per m2 (35 grams) Established Plants - Sprinkle around the plant and water in for best results. Apply 2 handfuls per m2 (70g) Soil Improver - Fork in feed to optimise soil conditions. Apply 2 handfuls per m2 (70g) Works best with: Flowers, Fruit, Vegetables, Trees and Shrubs
