Here's a slow-release fertilizer tablet recipe specifically designed for Strawberries 🍓 and Watermelons 🍉.
Banana peels – High in potassium (K) and phosphorus (P) for fruit development.
Eggshells – Provides calcium (Ca), preventing blossom-end rot.
Coffee grounds – Adds nitrogen (N) for leafy growth but in moderation to avoid excess acidity.
Cooked potatoes – Starch feeds beneficial microbes for healthier soil.
Sugar – Boosts microbial activity, helping roots absorb nutrients better.
Lentils – A natural nitrogen source, improving plant vigor.
2 banana peels (dried & powdered)
5 eggshells (crushed into fine powder)
½ cup coffee grounds (dried)
1 small cooked potato (mashed)
2 tbsp sugar (dissolved in warm water)
¼ cup soaked lentils (blended into a paste)
Binder (optional) – 1 tbsp cornstarch or gelatin dissolved in warm water
Dry banana peels & grind into powder.
Crush eggshells into fine powder.
Dry coffee grounds completely.
Mash cooked potatoes.
Soak lentils overnight & blend into a paste.
Dissolve sugar in warm water.
In a bowl, combine banana peel powder, eggshell powder, coffee grounds, mashed potato, and lentil paste.
Add sugar water and cornstarch or gelatin binder (if using).
Mix until a thick, dough-like consistency forms.
Roll into small balls (marble-sized) or press into a mold.
If too wet, add more dried coffee grounds or eggshell powder to absorb moisture.
Air dry for 2-3 days OR
Bake at low heat (150°F or 65°C) for 2-3 hours until firm.
Keep in an airtight container to prevent moisture.
For strawberries: Place one tablet per plant, 2 inches deep in soil.
For watermelons: Use 2-3 tablets per plant, spread around the base.
✅ High Potassium & Phosphorus → Supports big, juicy fruits.
✅ Slow Release → Prevents over-fertilization.
✅ Organic & Chemical-Free → Healthier soil & plants.
