How to Make Calcium Spray for Tomato Plants

Tomato plants require a sufficient supply of nutrients to thrive, and calcium is one of the essential elements they need. A lack of calcium can lead to disorders like blossom-end rot, which can ruin a tomato harvest. While there are many products available in stores to improve calcium levels in soil, making your own calcium spray is an affordable and easy option. Here's how you can do it:

Step 1: Gather Ingredients and Supplies

For this DIY calcium spray, you will require four common household ingredients:

Calcium carbonate powder - 4 tablespoons

Water - 1 quart

White vinegar - 2 tablespoons

Spray bottle

Step 2: Prepare Calcium Solution

Begin by dissolving the calcium carbonate powder in a quart of water. You can use tap water, but distilled water is preferable since it contains fewer impurities. Once the powder is entirely dissolved, add two tablespoons of white vinegar to the solution. The vinegar creates a reaction with the calcium carbonate that results in calcium acetate - this form of calcium is more accessible to the plant.

Step 3: Transfer Solution to Spray Bottle

Once you've made the calcium solution, it's time to transfer it to a spray bottle. A glass bottle is ideal since it won't react with the acidic solution. Make sure to label the spray bottle, so you know what's inside. You don't want to mistake it for a regular water spray bottle.

Step 4: Spray Tomato Plant

With the calcium solution ready, it's time to use it on your tomato plants. Spray the solution directly onto the leaves and the soil surrounding the plant. Be sure to cover the entire plant, so it gets the full benefits of the solution. You can do this once a week as part of your regular tomato plant care routine.

Step 5: Store Calcium Spray

After using the calcium spray, store it in a cool, dry place. The solution tends to settle, so give it a shake before using it for best results. The calcium spray can last for several weeks if stored correctly.

Conclusion

Tomato plants need calcium to produce a bountiful harvest, and making your own calcium spray is an affordable way to ensure that they get enough of it. With only a handful of ingredients and easy-to-follow steps, this DIY project is an excellent option for gardeners looking to improve the nutrient balance of their soil. By making and using this calcium spray regularly, you can help your tomato plants grow stronger, healthier, and more productive.
