Have you ever thought of using human urine in your garden? You might be surprised to know that it is a highly effective and organic way to fertilize your plants. Urine is rich in nitrogen, phosphorus, and potassium, which are essential nutrients plants need for growth. Moreover, it’s free and sustainable. In this article, we will discuss ten surprising ways to use human urine in your garden and how it can help you grow healthier plants.

1. Urinate directly on plants

It may sound strange, but urinating directly on plants is an effective way to fertilize them with nitrogen-rich urine. However, it’s crucial to avoid peeing on edible parts of vegetables and fruits, as well as young or fragile plants, as it could scorch the leaves and cause damage. Instead, aim for the soil around the plants or use a watering can to dilute the urine before applying it.

2. Urine as compost activator

If you have a compost pile, you can add urine to it as a compost activator. Urine contains beneficial bacteria that can aid in breaking down the organic matter in the pile, making it faster and more efficient. Moreover, the nitrogen content of urine will provide the compost with a nitrogen boost, which is crucial for plant growth.

3. Urine as foliar spray

You can also use urine as a foliar spray, which is a liquid fertilizer that you apply directly onto plant leaves. It’s best to dilute urine with water and a small amount of dish soap to make a gentle and effective spray. It’s an excellent way to provide plants with essential nutrients, especially during the growing season.

4. Urine as slug repellent

Slugs and snails can be garden pests that damage and eat your plants. However, human urine can be a useful and eco-friendly solution to repel them. Simply pour undiluted urine around the plants or in a line around your garden. The strong smell and acidity will deter slugs, and they will avoid crossing it.

5. Urine as deer and rabbit repellent

Urine can also help keep deer and rabbits away from your garden. It’s especially useful to protect young plants that may be vulnerable to their grazing. Pouring urine around the perimeter of your garden or creating a circle around specific plants will discourage them from coming near.

6. Urine as lawn fertilizer

If you have a lawn, you can use urine as a natural fertilizer. Simply dilute urine with water and use a watering can or spray bottle to distribute it evenly over the lawn. Urine is high in nitrogen, which is crucial for maintaining healthy green grass. However, avoid concentrating the urine in one spot, as it could burn the grass and cause patches.

7. Urine as weed killer

Did you know that urine can be a natural weed killer? Concentrated urine has a high level of acidity, which can kill certain weed seeds. Therefore, if you have an area in your garden that’s prone to weed growth, you can apply undiluted urine to control it.

8. Urine as citrus tree fertilizer

Citrus trees require specific nutrients to thrive. Urine is an excellent source of nitrogen, which is crucial for leaf growth and fruit development. You can use urine as a fertilizer for citrus trees by diluting it and applying it to the soil surrounding the tree. It’s an excellent way to provide your citrus trees with the necessary nutrients they need to produce healthy fruit.

9. Urine as tomato fertilizer

Tomatoes require a lot of nutrients to grow properly, particularly nitrogen, potassium, and phosphorus. Urine is an excellent source of these essential nutrients, making it a natural and effective tomato fertilizer. You can dilute urine and add it to the soil around the tomato plant, or spray a foliar spray on the leaves.

10. Urine as a natural insecticide

Human urine contains urea, which is a nitrogen-rich compound that can act as a natural insecticide. It’s an excellent alternative to commercially available insecticides, which can be harmful to beneficial insects and the environment. Dilute urine with water and spray it directly onto pests, such as aphids or spider mites, to control their population.

Concluding thoughts on human urine uses in the garden

In conclusion, using human urine in your garden can be a sustainable and cost-effective way to nurture healthy plants and protect them from pests and weeds. However, it’s crucial to use it correctly and safely. Always dilute urine before applying it, avoid using it on edible plant parts, and wash your hands after handling it. By following these simple guidelines, you can reap the benefits of urine fertilization without any risks.
