Garden Lime and Dolomite are commonly called soil sweeteners and what are soil sweeteners we hear you ask?
They both contain calcium carbonate which raises the pH in the soil to make it more alkaline. The added calcium in the soil increases the plant’s metabolic functions to aid the uptake of other nutrients like nitrogen and phosphorus - ideal for plant growth and to strengthens its defences against pests, disease and heat stress. The difference between the two is dolomite has additional magnesium.
Sulphur on the other hand decreases the pH in the soil making it better suited for acid loving plants like azalea, camellias and gardenias.
