Use Excess Cooking Liquids As Plant Fertilizer
Organic Liquid Fertilizer
Rice water or boiled food water is the new organic liquid fertilizer for your garden plants! It isn’t only easy to make and apply but it’s also packed with loads of nutrients your plants will absolutely love. Whenever you whip up a hearty meal and boil (or steam) some vegetables, pasta, or rice, instead of pouring the used water down the drain, use it in your garden to water your plants! Water from boiled eggs will also make a great liquid fertilizer as it's rich in calcium. Practicing this will make a great alternative to creating a compost pile since it requires less space and time to produce!

Turn Kitchen Leftovers Into Organic Liquid Fertilizer
Some of the best fertilizers don’t come in a bag; they come from your kitchen sink. That cloudy water left behind after boiling veggies or pasta? Liquid gold. For years, I’ve been pouring cooking liquids straight into my garden beds, and the results have been ridiculous—lush greens, happy blooms, and soil that feels alive.
Why Cooking Liquids Work
When you boil veggies, rice, or pasta, nutrients like potassium, phosphorus, and starches seep into the water. Tossing that down the drain is like throwing away free compost tea. Plants love these dissolved minerals. They drink them up as if you’ve treated them to a five-star meal.
One study found that starch-rich water can boost soil microbial activity, improving nutrient availability for plants.
Makes sense, doesn’t it? Keep the goodness cycling back into your garden instead of letting it swirl into your pipes.
How to Use Cooking Water Safely
First rule: Keep it plain. Salted water might as well be poison for plants. High sodium levels can wreak havoc on soil structure and roots. So, ditch the salt shaker if you plan to reuse the water.
Let the water cool completely before pouring it on your plants. Hot water can scorch roots, especially with seedlings or delicate varieties. Room temperature or slightly tepid is perfect.
What Works Best?
- Rice water: Loaded with starches that feed beneficial microbes.
- Vegetable water: A nutrient-packed brew, especially if you boiled root veggies like carrots or potatoes.
- Egg boiling water: Rich in calcium, perfect for tomatoes, peppers, or plants prone to blossom-end rot.
Skip greased-up or oily liquids. These coat the soil and block oxygen exchange. Save the bacon fat for other projects.
My Personal System
Every Sunday, when I prep a big batch of pasta, I save the starchy water in an old milk jug. It cools on the counter while I eat, then I use it to water my potted herbs. My basil practically sings afterward. The leaves double in size within a week—it’s wild.
During the summer, I collect veggie boiling water in a large bucket. As it cools, I dilute it by half with rainwater before pouring it around my tomatoes. I swear their flavor goes up a notch. Maybe it’s my imagination, but I’ll take it.
Pro Tips for the Best Results
- Use the water immediately or within 24 hours. Let it sit too long, and it’ll start to smell funky.
- Pour around the base of plants, not directly on leaves. This avoids any potential burning or bacterial issues.
- Rotate your liquid applications. Don’t use cooking water as your sole fertilizer; mix it up with compost or other organic feeds for a balanced diet.
Creative Ideas to Expand Use
Got an indoor plant jungle? Use cooled cooking liquids to give your houseplants a boost. I’ve seen snake plants perk up and spider plants send out runners within weeks.
Experiment with cold brew. Soak dried vegetable scraps in water for a day, then strain and use. It’s less nutrient-dense than cooking water but still a nice pick-me-up for less-demanding plants.
Final Thoughts on Kitchen Waste
Turning leftovers into organic liquid fertilizer is a no-brainer. It’s simple, free, and makes you feel like your garden has its own secret weapon. Next time you drain a pot of pasta, think twice before tossing it. Your plants will thank you.
