A common disease for most plants is blossom end rot and it happens due to insufficient calcium in the soil.

Eggshells are proven to increase the calcium in the soil and solve the problem. Here is a list of plants that like eggshells due to the added calcium:

Most of the above plants attract slugs and slugs can damage them. Preventing those slugs is easy with eggshells.

Apart from the above list, if any of your plants or bushes in the lawn or garden are prone to slug attack, you can use the eggshells to protect them.

Benefits of Eggshells: Behind The Scene Reason

Apart from providing valuable nutrients like calcium, such plants love the eggshells just for the natural protection from slugs as well.

Eggshell-loving plants are normally prone to damage by the snails and slugs. Crushed eggshells work like a deadly barrier to such pests because their soft bodies can be eviscerated by the jagged edges.

Calcium is an important and crucial regulator of the growth and development of plant life. Being enriched with calcium gives an extra boost to plants not yet grown and other thirsty plants.
