Eggshells are a valuable source of calcium and other microelements necessary for plant growth and development.
Many summer residents use it as a fertilizer, but there are nuances that are important to consider.
Anastasia Kovrizhnykh , an expert of the online publication BelNovosti, an agronomist and landscape designer, told how many times in the spring you need to feed strawberries and how to do it.
Using the shell in its raw form
Raw eggshells decompose very slowly and can attract rodents and other pests to the area. In addition, raw shells can contain pathogenic bacteria.
Excessive amount
Like any fertilizer, eggshells should be used in moderation. Excess calcium in the soil can upset the balance of nutrients and negatively affect plant growth.
Application for all crops
Not all plants respond equally well to eggshells. For example, it is contraindicated for crops that prefer acidic soils, such as hydrangeas, rhododendrons and azaleas.
How to Use Eggshells Properly
1. Crush the shells: Before using, the shells should be thoroughly crushed, for example in a coffee grinder. This will speed up their decomposition and increase their effectiveness as a fertilizer.
2. Bake in the oven: baking the shell in the oven at 150-200 degrees for 10-15 minutes will help kill bacteria and speed up its decomposition.
3. Add to compost: Eggshells are a great addition to a compost heap. They add calcium and other micronutrients to the compost.
4. Use for seedlings: Adding crushed shells to the soil for seedlings will help strengthen the stems of the plants and prevent black leg disease.
Harm or benefit
Eggshells are a valuable fertilizer that, when used correctly, can greatly benefit your plants. Avoiding common mistakes will help you get the most out of this natural source of calcium.
