Iron Transfer: The moisture and acidity of the banana start to slightly corrode the nails, allowing tiny amounts of iron to leach into the banana.
Natural Fertilizer: Once the banana has absorbed some of the iron, it becomes a rich source of iron, potassium, phosphorus, and other nutrients — all essential for plant growth.
Soil Booster: Bury the banana (with or without the nails) near the roots of your plant. As it breaks down, it slowly releases nutrients into the soil.
Why Use This Trick?
Iron Deficiency Fix: Great for plants showing yellowing leaves (a common sign of iron deficiency).
Chemical-Free Gardening: Avoids synthetic fertilizers.
Cost-Effective: Just grab a banana, a few iron nails, and you’re set.
Bonus Tips
Use steel (non-galvanized) nails for best results. Avoid anything coated or painted.
Pair it with coffee grounds for an even richer soil mix — coffee adds magnesium and nitrogen.
Let the banana sit for 10–20 minutes with the nails before burying it, or just bury the whole thing and let nature do the rest.
