Tomato paste is a surprisingly effective ingredient for making a simple foliar fertilizer. It’s rich in potassium and phosphorus, two key nutrients that support flowering and fruiting in tomato plants.
How to Make It:
Mix 2 tablespoons of tomato paste with 1 liter of water.
Stir until the paste fully dissolves and the mixture turns a deep red.
Pour this solution into a larger container and add 10 liters of water.
Stir thoroughly to combine.
How to Use It: Use this fertilizer as a foliar spray. Spray it directly onto the leaves of your tomato plants once a week. Foliar feeding allows plants to absorb nutrients more quickly through their leaves, providing an instant boost during the fruiting stage. This natural solution is gentle and safe, packed with vitamins, amino acids, and minerals such as magnesium and calcium.
3. Tomato Paste and Compost Tea Fertilizer
For an even more powerful blend, combine tomato paste with compost tea. This mixture provides both fast-acting nutrients and beneficial microbes that support long-term soil health.
How to Make It:
Mix 4 tablespoons of tomato paste with 1 liter of water until well blended.
Add this mixture to 8 liters of water in a larger bucket.
Add enough compost tea to make a total of 15 liters of fertilizer.
How to Make Compost Tea: Soak mature compost in water for 24–48 hours, then strain out the solids. The resulting tea is filled with nutrients and helpful microorganisms.
How to Use It: Apply the fertilizer directly to the soil around your tomato plants or use it as a foliar spray. The combination of tomato paste and compost tea enhances flower and fruit development while supporting healthy roots and microbial activity in the soil.
4. Overripe Tomato Fertilizer
Instead of throwing away overripe or damaged tomatoes, turn them into a nutrient-rich fertilizer for your garden. This method helps reduce kitchen waste while feeding your plants.
How to Make It:
Collect overripe or damaged tomatoes. Remove any parts that are diseased or pest-infested.
Blend the tomatoes with 1 liter of water to create a smooth juice.
Pour 1 liter of this juice into a large container.
Add 10 liters of water and 10 liters of compost tea.
Mix well and let the solution rest for 24 hours.
How to Use It: Apply the fertilizer to the base of your tomato plants or use it to water seedlings. The nutrients in the tomatoes, combined with the compost tea, promote healthy plant growth and soil improvement.
