3. Elixir Gardens

Elixir Gardens Calcium Carbonate | 1kg | Fine Calcium Flakes

Elixir Gardens - Our calcium carbonate is produced from a specialty, high purity source to ensure you receive the maximum calcium content. 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.

A calcium deficiency can lead to common fruit diseases such as blossom-end rot, which is prevalent in tomatoes and peppers. 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. Ground calcium carbonate is your ideal calcium choice for your next animal feed or nutrition supplement formulation to achieve optimal health for reptile shells, egg shells, farm animals and household pets.

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. Calcium is an important nutrient that strengthens a plant’s cellular walls and is vital in new cell development.
