How to Protect Tomatoes from Blossom End Rot: The Eggshell Trick

Blossom end rot appears as brown spots on tomato fruit.

This is caused by a lack of calcium in the plant, which is necessary for the formation of cell walls.

To prevent or treat blossom-end rot, you can use eggshells, which contain about 95% calcium, says Anastasia Kovrizhnykh .

How to Prepare Eggshells

To properly use eggshells as fertilizer, you need to follow a few recommendations:

• Wash the shell thoroughly to remove any remaining protein or yolk to avoid attracting pests.
• Dry the shells in the sun or in the oven until they become brittle.
• Grind the shells in a blender, coffee grinder or mortar until they become flour or grains.

Using Eggshells to Improve Tomato Growth

There are several methods of using eggshells in growing tomatoes.

When planting tomatoes, in open ground or pots, it is recommended to add crushed eggshells.

You can put 1-2 tablespoons in each hole or pot. This will help fertilize the soil and improve plant growth. This will provide the plants with calcium for the entire season and improve the soil structure.

During the growing season, you can sprinkle the shells around the stems of tomatoes once every 2-3 weeks.

This will help maintain calcium levels in the soil and prevent it from being washed away by rain or watering.

You can also make an infusion from the shell by pouring 100 grams of shell with 1 liter of boiling water and leaving it for 3-4 days. Then you can dilute the infusion with water in a ratio of 1:10 and spray the leaves and fruits of tomatoes once a week.

This promotes the absorption of calcium by plants and strengthens their immunity.

Eggshells are a simple and effective way to protect tomatoes from blossom-end rot.

It not only enriches the soil with calcium, but also improves its structure, increases moisture capacity and prevents the development of fungal diseases.
