Calcium is an important nutrient that strengthens a plant inch s cellular walls and is vital in new cell development. A calcium deficiency can lead to common fruit diseases such as blossom-end rot, which is prevalent in tomatoes and peppers. It is usually added in winter for annual crops, such as vegetables, just prior to digging, as the calcium carbonate can take effect over the winter months and will not damage young growth. Before planting perennial plants like lawns, shrubs, fruit or trees, apply if the soil is acid. To find out how much is required you need to check your soil pH. A soil pH test measures the acidity or alkalinity of the soil. A pH 7.0 is considered neutral. Above pH 7.0, the soil is alkaline and below pH 7.0, the soil is acid. Calcium Carbonate, in it's powdered form, is much faster acting than granulated garden lime, but a little more care must be taken when applying to make sure you get an even coverage. One role of calcium carbonate known to many professionals, but that is not necessarily common knowledge to the average home gardener, is its ability to mitigate heavy metals in the soil.
