As a professional gardener, I’m always seeking out new ways to feed my plants. I have steeped nettles in old buckets to brew a nitrogen-rich foliar feed, hoarded banana skins from the trash for a potassium fix, and even smashed eggshells to make a calcium-rich powder to sprinkle around the yard. But one method, recently back in the news, is raising eyebrows: using urine as plant fertilizer. Yes, really.
Hear me out. The ancient Greeks and Romans did it, after all. And while not everything from classical times deserves a revival, using urine as plant fertilizer might be worth reconsidering. You may have recently seen reports or heard talk touting this seemingly odd but smart solution that is a cost-free fertilizer packed with the very nutrients plants crave.
