This year, tipped off on Twitter, I carried out a bit of an experiment with a new plant food; one that is completely free and in plentiful supply. No, not my much-loved comfrey tea — something far easier to acquire that that.
There, I said it. I use urine on my plants, and I have to say that I think the results have been encouraging – it’s certainly something I’ll be doing in the future, possibly on my recently-planted garlic to give them a good start.
It may seem a little weird, but hey-ho – I pee’d in a recycled 4-pint milk bottle each morning for a few days at a time, then added the full bottle to a watering can. Once every two weeks during the main growing season was enough to notice a difference in the size of the crops. You’ll want to ease off on feeding when you get closer to harvesting time.
The photograph above shows the results of an onion taken from the row fed with “Agent Orange” and one from the row which was treated normally (occasional comfrey “tea” feeding, but otherwise left to their own devices).
You can read a little more about using your pee as a plant food at The Ecologist, except their article written by someone that knows why it works, rather than just that it does.
