Can I Use Cooking Water on Plants?

Many gardeners and environmentally conscious individuals have been wondering if they can use their cooking water on plants. The answer is not a simple yes or no because it depends on several factors such as what was cooked, how it was cooked, and whether there are any additives in the water.

Types of Cooking Water

Cooking water can be broadly classified into three types:

Veggie Water: This is the water left over after boiling vegetables, such as potatoes, carrots, and broccoli.

Pasta Water: This is the water used to boil pasta or other grains like rice, quinoa, or couscous.

Meat Water: This is the broth remaining after boiling meat or bones.

Using Veggie Water

Vegetable water is a nutritious liquid that can be used as a base for soups, stews, sauces or gravies. However, it contains starch, which can attract pests and bacteria. To avoid this, allow the water to cool and settle for a few hours before using. Also, avoid using veggie water from vegetables that were heavily sprayed with pesticides or that are known to absorb heavy metals from the soil, such as leafy greens.

Using Pasta Water

Pasta water is a popular ingredient in Italian cuisine as it helps to bring the sauce together and adds flavor. It contains salt and starch, which can help plants fight pathogens, retain moisture, and boost growth. However, it should only be used in small quantities as an occasional supplement to regular watering. Large amounts of salt can damage soil structure and kill beneficial microbes.

Using Meat Water

Meat water is rich in minerals, proteins, and fatty acids, which can nourish plants and improve soil fertility. However, it also contains salt, fat, and other additives such as MSG, which can harm plants, attract animals, and leave a bad smell. Meat water should not be used on plants that are meant for human consumption, and it should be diluted with water before applying to avoid over-fertilization or contamination.

Conclusion

In conclusion, using cooking water on plants is a good way to recycle nutrients and reduce waste, as long as it is done in moderation and with caution. Always ensure that the cooking water is clean, cold, and free from chemicals, oil or salt. Test the water on a small patch of plants first and observe any adverse effects. Using cooking water can be a great way to save money, nourish your plants, and do your part for the environment.
