Today’s post may seem a bit obscene to some people but I think it’s a great way to use a waste product and it’s free fertilizer. This free fertilizer is urine. Yep, good ole pee. (I’m glad my 6 year old son doesn’t read these posts or he’d be repeating that incessantly for the next week) Urine is composed primarily of water with the second component being urea. Urea is one of the main ingredients of fertilizers and provides the plant with nitrogen that is needed for foliar growth. With that being said, why not use what God has provided us already?
Let me throw out a few disclaimers here:
- Don’t use your urine if you are suffering from any illness. The last thing you want is for your soil and plants to be exposed to pathogens.
- Don’t use your urine as fertilizer on plants that you’ll be eating the greens from. Skip the lettuce, cabbage, spinach, etc. and instead focus on veggies like tomatoes and peppers.
- If you are growing your veggies in containers, dilute the urine before watering your plants. I can tell you from personal experience that you can quickly burn the roots of your plants if you don’t.
Speaking of burning your plants, it seems that men’s urine is much more potent than females. If your plants are in the ground and being watered on a regular basis, you shouldn’t need to dilute it first. If you live in an area with little precipitation, consider diluting it as the urine will act like a regular fertilizer and the salts can build up quickly in the soil. Also, don’t “fertilize” your plants every day; fertilize a couple of times and observe them for a few days. The urea is quickly absorbed by the plants and you should see results within a few days. If your plants still haven’t greened up after 3 days or so, give them another shot of fertilizer (pun intended) and wait for results.
I can’t think of a better way to get your son to help you in the garden. What boy doesn’t like to do his business outside? I know that mine does. An added benefit of using urine as free fertilizer is that it can help deter deer…for a while anyway. So, have you used free fertilizer in your garden? What kind of results have you had?
