If pepper or eggplant seedlings grow weak, pale, or do not produce new leaves for a long time, the problem may be in the soil. Plants lack nitrogen, potassium and organic matter, and store-bought fertilizers are not always needed, especially when you already have everything you need in the kitchen.
Instead of expensive fertilizers, use coffee grounds. It is rich in nitrogen, magnesium, potassium and organic acids, which gently nourish the roots and improve the structure of the soil.
How to use coffee grounds for seedlings:
- Collect any leftover tea leaves after making coffee.
- Dry them well on a radiator or in the air. This will prevent mold.
- Before planting seeds, add 1-2 teaspoons of dry grounds to each cup of soil per 200 ml of soil.
- Gently mix into the soil. Do not place the grounds directly under the seed.
- After picking, you can repeat: sprinkle a thin layer on top or pour in a weak infusion. Mix 1 tsp. grounds for 0.5 liters of water, let it brew for 12 hours.
Coffee grounds loosen the soil, improve drainage, and slowly release nutrients. After just 10–14 days, you will notice that the leaves have become darker, the stems are stronger, and the growth is even.
Another plus: coffee grounds repel whiteflies and sciarids, which often infest greenhouses and window sills.
This method is ideal for those who grow seedlings at home and want to do without chemicals. It is especially effective on poor, store-bought soils where there is a lack of living organic matter.
But don't overdo it. Coffee grounds are good in moderation. Excess can acidify the soil, especially for peppers. It is better to add it little by little and observe the reaction of the plants.
