Tuna Can Test: The Secret to a Perfect Lawn?

Just read this article about the tuna can test. Apparently, you place an empty tuna can in your yard while watering, and when it fills up, you've watered enough. Sounds too simple to be true, but they say it prevents overwatering and killing your lawn. What do you all think? Has anyone tried this?

Haha, I've heard of that trick before! It's a classic. I actually tried it last year after a bout of overwatering. My lawn was all mushy and yellow. The tuna can method helped me gauge how much water I was putting down. It's a handy low-tech solution, especially for those of us who aren't tech-savvy with sprinkler systems.

I'm a bit skeptical. I mean, a tuna can is only about 1.5 inches deep. Is that enough? I usually water for about 30 minutes per zone. Maybe I should double-check with this method. But I suppose if it works for some, why not? Might be worth a shot for the newbies.

Yeah, I've heard of it too. It''s actually a pretty standard way to measure sprinkler output. The key is to see how long it takes to fill the can with 1/2 to 1 inch of water. That tells you your precipitation rate. Then you can adjust your watering schedule accordingly. It's not just a random can, it's a simple measuring tool.
