Keep the cooking water

I recover the cooking water from my vegetables and use it to water indoor plants or those on my balcony. This saves water while delivering essential nutrients that fertilize my plants naturally.

I noticed the difference quickly: their leaves turned a deeper green with a healthy shine, standing out from my neighbors' plants.

Wait until the water is cold

Always let the cooking water cool completely before use—a simple step to protect your plants' roots.

Eggshells, an extra natural fertilizer

Eggshells provide minerals like calcium to enrich your soil. Reuse the cooking water from boiled, soft-boiled, or poached eggs for your plants.

For a supercharged boost, add crushed shells to your watering can and let them steep for a few hours. Keep them at the bottom for ongoing use.

My little bonus

If you have an aquarium or fish bowl, repurpose the water changes as plant food. Fish waste adds phosphorus and nitrogen—ideal for lush green plants!
