Can You Use Washing Up Water on Plants?

Water is one of the most important elements of a plant’s life. It is crucial to their growth and development. While most of us prefer to use fresh water to water our plants, it’s natural to wonder if we can use washing up water instead, especially in areas that face water shortages. In this article, we’ll explore whether washing up water is safe for plants or not.

What is Washing Up Water?

Washing up water, also known as dishwater, is the water that’s left over after washing dishes. It’s usually a mixture of soap, food particles, and water. The use of soap means that the water is no longer clean and may contain potentially harmful chemicals or substances that could harm plants.

The Risks of Using Washing Up Water on Plants

While using washing up water on plants may seem like an excellent way to reuse water, it’s not always safe for plants. Dish soap, for example, can be harmful to plants as it can disrupt their natural pH balance and damage the plant’s natural protective coating. Additionally, food particles can attract pests and insects that can damage your plants or even spread diseases.

Washing up water may also contain oils and fats, which could create a film over the plants’ leaves, blocking the plant’s natural ability to photosynthesize. This can lead to stunted growth, yellowing of the leaves, and even death.

When Can Washing Up Water Be Safe for Plants?

Although using washing up water isn’t recommended, there are some situations where it can be safe for plants. For example, if you’re washing dishes with eco-friendly soap and you haven’t cooked with oils or other fats, the water you use may be safe to use on plants. Also, if you have a vegetable garden, you should avoid using washing up water on any plants that will be consumed.

Alternatives to Using Washing Up Water on Plants

If you’re looking for a way to reduce your water usage without harming your plants, there are several alternatives available that can help you achieve your goal. One option is to collect rainwater and use it to water your plants. This water is naturally pure and has no chemicals, making it an excellent choice for plants.

Another option is to invest in a greywater recycling system that reuses water from your shower or washing machine to irrigate your plants. This water is pre-filtered to remove any harmful chemicals or particles, making it safe to use on plants.

The Bottom Line

In conclusion, while the idea of using washing up water on plants may seem like a good idea, it’s not always safe for them. The soap, nature of the water, and other factors can harm your plants or even spread dangerous diseases. Instead of using washing up water, consider using rainwater or investing in a greywater recycling system to minimize your water usage while still keeping your plants healthy and happy.
