Can You Use Washing Machine Water on Plants?

Many people wonder if it is safe to use washing machine water on plants. After all, who wouldn't want to save water and be more eco-friendly by reusing what would otherwise go down the drain? However, before you start diverting your greywater to your garden, there are some things you need to consider.

The Risks of Using Washing Machine Water on Plants

Washing machine water can contain a variety of substances that could harm your plants, including:

Soap and Detergent: Most laundry detergents contain chemicals that are harmful to plants, such as phosphates, boron, and sodium. These chemicals can build up in the soil over time and affect the growth of your plants.

Fabric Softener: Fabric softeners contain chemicals that can harm plants and even be toxic to humans and animals.

Bleach: Chlorine bleach can kill plants and damage soil health.

Hair and Lint: Hair and lint can clog your plants' pores, making it harder for them to absorb nutrients and water.

So, before you start using washing machine water on your plants, make sure you know what's in it. Check the labels of your laundry detergent and fabric softener to see if they contain any harmful chemicals, and avoid using bleach or other additives in your laundry.

Tips for Using Washing Machine Water on Plants

If you're determined to use washing machine water on your plants, there are some steps you can take to minimize the risks:

Use a Filter: Use a filter to remove hair and lint from the water before using it on your plants.

Use Eco-Friendly Detergent: Choose a laundry detergent that is eco-friendly and doesn't contain harmful chemicals.

Dilute the Water: Dilute the washing machine water with fresh water before using it on your plants to reduce the concentration of harmful substances.

Don't Overuse: Don't use washing machine water on your plants every time you do laundry. Instead, alternate with fresh water to give your plants a break.

Remember, just because you can use washing machine water on plants doesn't mean you should. If your plants are struggling or showing signs of damage, it may be best to stick with fresh water until you figure out the cause of the problem.

The Bottom Line

Using washing machine water on plants can be a great way to save water and be more environmentally friendly, but it's important to be aware of the risks and take steps to minimize them. If you're unsure about the quality of your washing machine water, it's best to err on the side of caution and use fresh water instead.
