How to Feed Calcium to Tomato Plants

Tomatoes are one of the most popular vegetables to grow in a garden. However, they are notorious for developing a common condition known as blossom end rot, which is caused by calcium deficiency.

What is Calcium and Why is it Important for Tomatoes?

Calcium is a vital nutrient for plants and is essential for tomato growth and development. It helps to maintain cell walls, proper root development, and to prevent diseases. A lack of calcium can cause deformation, reduced fruit set, and, as previously mentioned, blossom end rot.

Ways to Introduce Calcium to Tomatoes

There are a few ways to introduce calcium to tomato plants, both before planting and during their growth cycle. Here are a few methods you can use:

Pre-Planting

Before planting, you can spread crushed eggshells or oyster shells around the planting area. These shells will break down over time and release calcium into the soil.

Using Calcium-Rich Fertilizers

You can use fertilizers that contain high amounts of calcium, such as bone meal or gypsum. Follow the instructions on the fertilizer packaging for proper application.

Add Calcium to the Soil

Calcium can be added directly to the soil, either by mixing it in during soil preparation or by using a foliar spray during the growing season. There are several products on the market that are specifically designed for tomato plants and provide a good source of calcium.

Tips for Preventing Blossom End Rot

Although calcium is essential to preventing blossom end rot, there are other factors that can contribute to the condition. Here are a few tips to help prevent blossom end rot in your tomato plants:

Ensure the plants receive adequate water, but avoid overwatering

Try to keep the soil consistently moist, but not soaked

Avoid excessive use of nitrogen fertilizer, as it can inhibit calcium uptake

Ensure the soil pH is between 6.0 and 6.5

Avoid planting tomato plants in an area that has previously had blossom end rot issues

In Summary

Calcium is an essential nutrient for tomato plants and can be added to the soil before planting, through fertilizers, or via foliar sprays during the growing season. Along with controlling calcium levels, ensuring consistent soil moisture and avoiding excessive nitrogen usage can help prevent blossom end rot in your tomato plants. By following these tips, you can enjoy a bountiful tomato harvest with healthy, ripe fruits.
