Ah! You’re asking about free liquid fertilizer—so, nutrient-rich liquids you can use for plants without spending money. There are actually several common options, usually using kitchen scraps or household items. Here’s a thorough guide:
1. Compost Tea
- What it is: A nutrient-rich liquid made by steeping compost in water.
- How to make:
- Fill a bucket with water.
- Add a shovelful of finished compost (or vermicompost).
- Stir and let it sit for 24–48 hours.
- Strain the liquid and use it to water plants.
- Benefits: Provides nitrogen, phosphorus, potassium, and beneficial microbes.
2. Kitchen Scraps Tea
- Vegetable scraps: Onion skins, carrot peels, potato skins, and leafy greens.
- How to make:
- Boil or soak scraps in water for 24 hours.
- Strain and use the liquid for watering.
- Benefits: Slow-release nutrients, mostly nitrogen and potassium.
3. Coffee Grounds or Used Tea
- Used coffee grounds: Steep in water for a few hours.
- Used tea leaves/bags: Can also be steeped in water.
- Benefits: Adds nitrogen and slightly acidifies soil (good for tomatoes, peppers, blueberries).
4. Banana Peel Water
- What it is: A simple way to add potassium and phosphorus.
- How to make:
- Chop banana peels and soak in a jar of water for 24–48 hours.
- Strain and water plants.
- Best for: Flowering plants and fruiting vegetables.
5. Eggshell Tea
- What it is: Provides calcium for plants.
- How to make:
- Crush clean eggshells.
- Boil them in water for 10–15 minutes.
- Let cool, strain, and water plants.
- Best for: Tomatoes, peppers, and other calcium-loving plants.
Tips for Using Free Liquid Fertilizers
- Apply every 1–2 weeks.
- Use diluted for strong teas (especially compost or coffee) to avoid burning plants.
- Combine types: For example, compost tea + banana peel water gives a broader nutrient spectrum.
- Always stir before use, as nutrients may settle at the bottom.
