Urinating on my Tomato Plants

Posted on Sep 23 2009 - 4:00am by Mike Lieberman

There’s been a lot about urine in the news lately. Juan Manuel Marquez was saying that he was drinking his own urine leading up to his fight with Floyd Mayweather.

As fascinating as that story is, the story that piqued my interest even more was the one about urinating on your tomatoes and how it can help to give you fruits four times larger.

I decided to give it a go and urinated on my cherry tomato plant on my fire escape garden. Don’t worry before I started, I looked and gave a yell so no one got hit with some unexpected rain.

According to the research done by the Finnish team, it’s actually a mixture of urine and wood ash that is the ultimate eco-friendly fertilizer. I just used my urine.

    LMAO! Love it! Plus the tomato shot is even better!

  2. Mike Lieberman September 23, 2009 at 7:25 am -

    Thanks. It's all about experimentation.

    You're such a freakin' rockstar. Love ya, bro.

  4. Mike Lieberman September 23, 2009 at 8:26 pm -

    Haha. Thanks Mike. Figured it was worth a shot.

    LOL, how nice of the upstairs neighbor to catch that shot!

    Four times larger, heh? So, have the cherry toms turned into beefsteaks?

  6. Mike Lieberman September 24, 2009 at 8:07 am -

    LOL. Not yet. Need to nourish them some more.

    Just an excuse for public urination *tsk tsk*

    Lol!

    It'll be interesting to see if it works!

    That's awesome! Gardeners add animal waste all the time to their gardens, so what's so different if we add our own? Go humanure!

    Since I left college, I've been looking for excuses. Should've grown tomatoes years ago.

  10. Mike Lieberman September 24, 2009 at 12:28 pm -

    Word up. I'm down with that.

    Lemme see ya do the solids thing, faint heart! I dilute mine about three parts water to one urine, not to burn tender roots and chutes! It works great! France has done it for centuries, China even longer, and guess what! It works very well.Look on Google, see the large green rings around Asian cities? They buy and sell the stuff, fight over collection rights, and don't always pre-treat solids giving way to parasite outbreaks from time to time, and all preventable! America must learn to bio-gas all its humanure to fuel and topsoil building fertilizers, radiated to safety standards, before it is too late and we start getting sewage residues in our drinking water, and spoil all our lakes, rivers and seashores, but in a corporate world the question is, as always, “Who pays”? And nobody steps up to the plate! Time methinks for a socialist legislation, making everyone who Shiites pay, and in America, everyone Shiites! P.S. Oslo, capital of Norway runs buses on biogas from sewage as we speak, and pay smaller fuel oil bills for their efforts, see web for details!

    I hope you wash them first! I suppose you it's a good source of urea for the soil 🙂

    Lemon trees love it too!

  14. Mike Lieberman September 24, 2009 at 8:19 pm -

    Wow not really sure how to respond to that one. Thanks for the comment though.

  15. Mike Lieberman September 24, 2009 at 8:19 pm -

    Unfortunately, no lemon tree on the fire escape.

  16. Susan September 25, 2009 at 5:19 am -

    This is truly a brilliant idea. No toilet seat to put down. Doesn't matter if you miss. No one has to clean up after you…

    Wish I knew about this when my 4 sons lived at home.

  17. Mike Lieberman September 25, 2009 at 3:09 pm -

    Thanks for the comment Susan. Well the people down below might care. Luckily no one was hurt during that photo.

    I have been reading about this too. Did it work?

  20. Mike Lieberman October 8, 2009 at 4:19 pm -

    Too early to tell at this point. Might've done too late in the season, but no harm was done.

  21. Name October 10, 2009 at 4:28 pm -

    If you pee on your compost when you first start it up it will compost way faster. Gross but true.

  22. Mike Lieberman October 11, 2009 at 12:37 pm -

    Interesting. I'll have to take that into consideration for next spring. Thanks for the tip.

    Hey Mike,
    Dig your style buddy.
    Gonna give it a go on my roma's this season and let you know if I end up with prize winners.

  24. Mike Lieberman October 18, 2009 at 10:50 am -

    Thanks. Def keep me updated.

    I hate to tell on something that has embarrassed me for years, but my mom has always did a combo of urine and something else (?)…I wasn’t listening…yuck. But, she won her neighborhood YARD of the SEASON every year! Wonder what her secret is? 🙂

  28. Joseph Rice May 9, 2011 at 1:38 pm -

    mike, if i’m outside and need to pee, i just head over to the compost pile and let it go. i would think there are excess minerals in urine that would be beneficial to the compost pile.

  29. Mike Lieberman May 9, 2011 at 1:46 pm -

    Absolutely.

  30. Mike Lieberman May 9, 2011 at 1:46 pm -

    Don’t worry. I won’t tell 😉

    Nice one Mike. Actually urine is a rich source of the nitrogen plants need to grow. Yellowing leaves is usually a sign of nitrogen deficit. Another way to add it to soil is through coffee grounds or to a lesser extent, tea leaves.
    The only danger with direct hosing is that the ammonia may burn the plants. Churning it into compost is a workaround. I know that’ll work great with your indoor composter 😉

  32. Mike Lieberman June 13, 2011 at 1:23 am -

    Thanks for the advice!

  33. Edward November 2, 2011 at 9:44 am -

    I piss in my compost pile(s) to take away the need for flushing water down the toilet, and it really helps speed up the process too. I’ve done that with tomatoes in the past, except I went in a gallon jar and diluted it with 8X water – 1X urine.

  34. Mike Lieberman November 2, 2011 at 11:19 am -

    That’s what’s up!

    Wanna’ see your skin glow? Nature’s toner. And if I’m really sick, I already know what will heal me. It’s all within. Call me when the tomatoes are ready. 🙂

  36. Mike Lieberman January 22, 2012 at 5:48 pm -

    Nice!

  37. Vanessa Pruitt April 27, 2012 at 1:42 pm -

    Love it. Only for the truly dedicated gardeners… :p

  38. Mike Lieberman April 30, 2012 at 5:28 am -

    That’s how I roll.

  39. Activate May 1, 2012 at 8:51 am -

    So… how big are they? 😉

  40. Mike Lieberman May 1, 2012 at 10:24 am -

    Wouldnt you like to know?

  41. Guest July 5, 2012 at 2:39 pm -

    Did it help? How often did you pee on them? This is fascinating.

  42. oscar5261 September 15, 2013 at 3:47 pm -

    You guys probably masturbate on your plants too. NO ORGANIC S— for me!
