What Does Egg Shells Do for Tomato Plants?

Egg shells, the hard outer layer that encases the liquid and soft contents of an egg, are surprisingly beneficial for tomato plants. Instead of throwing them away, gardeners should consider reusing them in their gardens. Here are some of the benefits of using egg shells for tomato plants:

Improves Soil Quality

Tomato plants require a specific type of soil to thrive, called loamy soil. This soil type contains equal parts of sand, clay, and silt, and is slightly acidic with a pH range of 6 to 6.8. Egg shells, when crushed into small pieces, can help improve the texture and nutrient content of the soil. The shells are high in calcium carbonate, which helps neutralize acidic soils, making it more favorable for tomato plants.

Provides Calcium to Tomato Plants

Tomato plants require a significant amount of calcium to thrive. Low calcium levels can lead to blossom end rot, a disease that causes the bottom of the tomato fruit to turn black and mushy. Egg shells, when ground into a fine powder, provide the perfect source of calcium for tomato plants. The eggshells are composed of 95% calcium carbonate, which is easily absorbed by the plant.

Deters Pests

Tomato plants are prone to various pests such as slugs, snails, and cutworms that can cause significant damage to plants. Fortunately, egg shells can help deter these pests. The sharp edges of the crushed egg shells act as a physical barrier, making it difficult for pests to feed on tomato plants. Additionally, the calcium-rich egg shells can repel various insects such as ants, aphids, and spider mites, which are often attracted to calcium-deficient plants.

Promotes Decomposition

Egg shells break down slowly, making them an effective soil amendment that can last for months after being added to the soil. The slow decomposition process helps to retain moisture and improve soil structure. Tomato plants benefit from the improved soil structure, as it allows roots to grow freely and absorb essential nutrients from the soil. This, in turn, helps tomato plants to grow healthier and produce higher yields.

Conclusion

In conclusion, egg shells are an excellent addition to gardens, especially for tomato plants. They help improve soil quality, provide essential calcium, deter pests, and promote decomposition. Gardeners should consider reusing egg shells in their gardens, rather than throwing them away. It is a simple but effective way to help their tomato plants grow healthier and produce more abundant yields.
