Simple watering for tomatoes, peppers, cucumbers and strawberries can be prepared from ordinary kitchen leftovers. Coffee grounds, banana peels, eggshells, onion peels and other waste turn into a nutritious solution that supports growth, flowering and fruit formation.

These plants consume many nutrients during the season. Instead of buying expensive fertilizers, you can use what you would otherwise throw away.

The advantage is that homemade solutions are gentle and you can adjust the composition according to the current needs of the plants.

Basic principles of homemade watering

Always use settled or rainwater. Do not pour cold water directly from the tap.

Dilute concentrated infusions before use. Strong solution can damage roots.

Water at the roots, not on leaves. This reduces the risk of fungal diseases.

Apply in the morning or evening when the sun is not strong.

Coffee grounds for nitrogen and acidity

Used coffee grounds are a source of nitrogen and help slightly acidify the soil, which suits many vegetables.

Mix a handful of dry grounds with water and let it stand for a few hours. Dilute and water the plants.

Suitable for tomatoes, peppers and strawberries. Use sparingly so you do not overdo nitrogen.

Banana peels for potassium

Banana peels contain a lot of potassium, which is important for fruit formation and plant resistance.

Chop peels, pour water and let infuse for several days. Strain and dilute before use.

Excellent for tomatoes, peppers and strawberries during flowering and fruiting.

Eggshells for calcium

Crushed eggshells supply calcium and help prevent blossom end rot on tomatoes and peppers.

Crush shells finely, pour water and let stand. Use the infusion at the roots.

You can also sprinkle crushed shells directly on the soil.

Onion peels for resistance

Onion peels contain substances that support plant health and help against some pests and diseases.

Boil peels in water, let cool and strain. Use as foliar spray or root watering.

Good for all listed plants as prevention.

How to combine ingredients

You can prepare a universal infusion by mixing several ingredients. For example coffee grounds, banana peels and onion peels.

Let the mixture infuse for several days, strain and dilute.

Experiment with proportions according to what you have available and how the plants react.

Tips for success

• Always dilute infusions.
• Monitor plant reaction and adjust frequency.
