What Does Calcium Do for Plants

Calcium is important to provide structural support to cell walls.

Calcium uptake in a plant is a passive process. It is taken up through the soil with water. For this reasons, calcium uptake is directly related to a plant’s transpiration rate. Anything that slows this process such as high humidity, cold temperatures, or high levels of other nutrients, will induce calcium deficiency.

When a plant is deficient in calcium, newer growths will often be distorted from the improper cell wall formation. This may be demonstrated in new growths such as root tips, shoots, or young leaves. What often results is something that can be described as leaf edge necrosis or leaf burn.

Not all fertilizers contain calcium. This is why it is important to look at the fertilizers label to check if it contains secondary nutrients. If it is not in the fertilizer itself, you will have to supplement your fertilizer with calcium.

Most calcium that is found in fertilizers are found in the form of calcium nitrate. Calcium nitrate is basic, so it can raise the pH of the soil that you use the fertilizer in. Make sure that if you are adding calcium nitrate that you take this into account as some plants like acidic environments. 

Other Secondary Macronutrients

Other than calcium, there are other macronutrients that plants need.

Sulfur and magnesium are two other important secondary macronutrients that plants need. 

Also be sure to check out the primary macronutrients that are often displayed on fertilizer bags as N-P-K

If you are looking for the best macro and micronutrients for your plant, I highly recommend checking out Earthpods capsuled fertilizer which delivers the correct nutrients through microbes. You can definitely have success with other fertilizers, but it’s what I recommend for the healthiest plants.
