How to Give Tomato Plants Calcium

Tomato plants are one of the most popular crops for home gardeners. However, fruit development in tomato plants can be hindered by a lack of calcium. Calcium is an essential nutrient for tomato plants and helps prevent issues such as blossom end rot. In this article, we will discuss the different ways you can give your tomato plants the calcium they need to thrive.

Use Calcium-Rich Fertilizers

One of the easiest ways to give your tomato plants the calcium they need is by using calcium-rich fertilizers. There are many fertilizers on the market specially formulated for tomato plants that contain calcium. You can also use a general-purpose fertilizer that contains calcium, such as bone meal or fish meal.

When using calcium-rich fertilizers, it's important to follow the recommended application rates, as too much calcium can also have negative effects on your plants.

Add Lime or Gypsum to Soil

If your soil is deficient in calcium, adding lime or gypsum can help. Lime is a soil amendment that raises soil pH and adds calcium. Gypsum, on the other hand, does not affect soil pH but adds calcium and improves soil structure. Both lime and gypsum can be added to the soil before planting or during the growing season.

It's important to note that adding lime or gypsum to soil that already has adequate calcium levels can cause imbalances and negatively affect your plants.

Use Crushed Eggshells

Eggshells are a rich source of calcium and can be used to provide your tomato plants with this essential nutrient. Crushed eggshells can be added to the soil before planting, or you can sprinkle them around the base of your plants during the growing season.

It's important to finely crush the eggshells, as large pieces can attract pests and take longer to break down and release calcium into the soil.

Grow Companion Plants

Companion planting involves growing plants that complement each other in the same space. Some plants are known to be calcium accumulators and can help supply your tomato plants with this nutrient. Plants such as comfrey, borage, and horsetail are high in calcium and can be grown alongside your tomato plants.

Additionally, growing plants that have an association with beneficial mycorrhizal fungi can also help increase calcium availability in the soil. Plants such as beans, peas, and clover are known to have such an association.

Conclusion

In conclusion, providing your tomato plants with calcium is essential for healthy growth and successful fruit development. Calcium-rich fertilizers, lime, gypsum, crushed eggshells, and companion planting are all effective ways to give your tomato plants the calcium they need. Ensure you follow recommended application rates and avoid over-fertilizing, as too much calcium can also have negative effects on your plants.
