Some homemade mixtures are commonly used in plant care. But how do you prepare rusty nail water, banana and onion peel water, and rice water? What are their possible uses, and how should they be diluted?

1- RUSTY NAIL WATER

• Preparation: Place a few rusty nails in clean water and leave them to soak. Over time, the water may turn brownish.
• Uses: Traditionally used as a source of iron for plants. However, the amount of plant-available iron is uncertain, so it is not a reliable treatment for iron deficiency.
• Dilution: There is no scientifically established safe dilution ratio. Its application to plants is therefore not recommended.

2- BANANA & ONION PEEL WATER

• Preparation: Add one banana peel and the outer skins of one onion to 1 liter of clean water. Let the mixture sit for 12–24 hours, then strain.
• Uses: Small amounts of minerals and organic compounds may enter the water. It can be tested as a supplementary treatment for ornamental plants, but it cannot replace proper fertilizer.
• Dilution: For a cautious trial, mix 1 part of the preparation with 3–4 parts clean water. This ratio has not been scientifically validated.

3- RICE WATER

• Preparation: Rinse uncooked rice in clean water and collect the cloudy white water in a separate container.
• Uses: Rice water contains starch and small amounts of other substances. It is sometimes used in plant care, although its benefits have not been conclusively established.
• Dilution: For a small trial, mix 1 part rice water with 2–3 parts clean water.

IMPORTANT TIPS!

✅ Avoid storing homemade mixtures for long periods.

✅ Never use mixtures that smell unpleasant or show signs of mold.

✅ Test a small amount on one plant first.

✅ Excessive use may disturb the balance of the soil.

Remember: Every plant has different needs. Homemade mixtures are not guaranteed to be beneficial. Proper watering, adequate light, and balanced nutrition remain essential for healthy plant growth.
