How to Add Calcium to Potted Plants

Potted plants require adequate amounts of nutrients to grow and remain healthy. Among the essential nutrients needed by plants is calcium, which plays a vital role in the growth of cell walls and root development. Unfortunately, many potting soils lack sufficient calcium content, which can hinder plant growth and development. To ensure your potted plants receive the necessary calcium, consider implementing the following measures:

Test Your Soil's Calcium Content

Before adding calcium to your potted plants, it is vital to test the soil's calcium content. Testing soil in potted plants is a straightforward process that requires a home soil testing kit. Use the kit to measure the calcium levels and adjust the soil accordingly. This will give you an idea of how much calcium your plant needs to grow and develop adequately.

Add Calcium-Rich Fertilizer

One of the easiest ways to add calcium to potted plants is by using calcium-rich fertilizers. You can buy specialized fertilizers that are designed to add calcium to the soil from garden centers or online stores. Alternatively, you can add calcium supplements such as eggshells and bone meal to the soil. These supplements are an inexpensive way to increase calcium levels in potted plants.

Use Calcium Nitrate

Calcium Nitrate is a water-soluble calcium supplement that is easy to use in potted plants. It is quickly absorbed by the plant's roots, making it an efficient way of adding calcium to potted plants. To use calcium nitrate, dissolve a tablespoon of calcium nitrate in a gallon of water and use the solution to water your potted plants. However, be careful not to over-apply calcium nitrate, as excessive calcium can hinder nutrient uptake by the plant’s root system.

Use Calcium Chelates

Calcium chelates are organic compounds that bind calcium ions, making them available to plants. They are an excellent option for potted plants with high pH levels or those that are prone to calcium deficiencies. Calcium chelates are available in both liquid and granular forms and can be easily mixed with water and applied to the soil by watering the plants. When applying, follow the instructions on the label, and avoid over-application to prevent over-fertilization or plant toxicity.

Conclusion

Calcium is an essential nutrient required by potted plants for healthy growth and development. Lack of sufficient calcium can lead to stunted growth, blossom-end rot, and other issues. Adding calcium to potted plants is a straightforward process that can be accomplished by using specialized fertilizers, supplements, or calcium chelates. It is also essential to regularly test the soil's calcium levels to ensure your plants receive the necessary nutrients to thrive.
