Made Pasta? Save Your Leftover Water for Your Houseplants

A person pours pasta into a colander.

Most of us are used to dumping leftover water after making pasta. But if you have any houseplants, set that pot of water aside before pouring it down the drain.

Next time you make pasta, save the leftover water to feed your houseplants.

Starchy water promotes healthy bacteria in the soil. That bacteria is what helps to break down organic material, and when it’s broken down, the nutrients are distributed throughout the soil, making it to the roots for a natural boost. Most plants will love this new addition to their diet, but it’s better to mist pasta water for sensitive cacti or succulents rather than add it directly to their roots.

Just make sure to let the water cool completely before watering your plants. Boiling water can kill your indoor plants.

This kitchen duo is perfect for cooking pasta or rice to create starchy water.

But don’t go overboard with this trick. Only use the feeding method once a month. Yes, the starchy water increasing good bacteria in the soil can be good for your plant, but too much might harm your plant’s roots. It’s also full of carbs, which aren’t always the healthiest for your plant’s diet. Make sure to switch it up with store-bought fertilizers as well.

So instead of throwing out your pasta water, feed it to your houseplants. You can also use starchy rice water or leftover coffee to water your plant babies.
