How Often to Put Calcium Nitrate on Tomato Plants

If you're a tomato grower, you know that calcium is an essential nutrient for your plants. Calcium plays a critical role in forming the cell wall of plant tissue, helping to keep the plant strong and healthy. Calcium also prevents blossom end rot, a common problem in tomato plants. One way to ensure your plants receive enough calcium is by applying calcium nitrate to the soil. But how often should you do it?

The Importance of Calcium Nitrate

Calcium nitrate is a water-soluble fertilizer that is a combination of calcium and nitrogen. Calcium nitrate dissolves quickly in water, making it easy for plants to absorb the nutrients. Calcium nitrate is commonly used in hydroponic systems, but it also works well for soil-grown plants. Calcium nitrate is an excellent source of calcium for tomato plants, and it can also help boost plant growth and development.

When to Apply Calcium Nitrate

The best time to apply calcium nitrate to tomato plants is when the plants are actively growing. Most tomato plants start to grow after the last frost and continue growing throughout the summer. You can apply calcium nitrate to the soil every two to three weeks during the growing season. If you notice signs of calcium deficiency, such as blossom end rot, you can increase the frequency of application.

How to Apply Calcium Nitrate

To apply calcium nitrate, mix the fertilizer with water according to the instructions on the package. You can apply calcium nitrate to the soil around the base of the plant or spray it directly onto the leaves. If you apply calcium nitrate to the soil, be sure to water the plants thoroughly to ensure the nutrients reach the roots. If you apply calcium nitrate to the leaves, be sure to do it early in the morning or late in the evening when the sun is not too strong. Applying calcium nitrate to the leaves in direct sunlight can cause leaf burn.

Precautions When Applying Calcium Nitrate

When applying calcium nitrate, be sure to wear gloves and eye protection. Calcium nitrate can be harmful if it comes into contact with your skin or eyes. Avoid inhaling the fertilizer as well. Store calcium nitrate out of reach of children and pets.

Conclusion

Calcium nitrate is a valuable fertilizer for tomato plants. Applying calcium nitrate every two to three weeks during the growing season can help ensure your plants receive enough calcium to stay healthy and strong. Always follow the application instructions on the package and take precautions to protect yourself when handling the fertilizer.
