One of the ways to green up your lawn is with aged urine. Some sources suggest that fresh is better. Pee becomes ammonia eventually. This may damage some plants if placed in 1 spot too often. Although I age the pee, this may not be the best solution for things like flowerbeds where you might apply it in a more concentrated way. I have not been particularly rigorous, scientifically speaking, regarding the pros and cons of aged vs fresh. I would like to know other people's results.
Marking your turf.... Inspired by "Never Cry Wolf"**:
When the author, Mr Mowat was studying wolf behavior in the arctic circle, he marked his territory with urine. The wolves respected his boundary.
When my friends were purchasing mountain lion urine to accomplish the same thing, it struck me as an unnecessary expense.
1) Collect Pee in bottle.
2) (optional) Age it. This produces ammonia
3) Pour Pee around the yard.
It seems to work. The lawn has greened up where I do this, and I no longer see large canine prints (presumably from coyotes, which live in the area) in the snow. I can surmise that the coyotes no longer consider this their turf. But, again, more than 1 variable has changed, so this correlation may not prove causation.
* the following is from PBS site on Jerry Bakers lawncare:
"All-Season Green-Up Tonic
1 can of beer,
1 cup of ammonia,
1/2 cup of dishwashing liquid,
1/2 cup of liquid lawn food, and
1/2 cup molasses or corn syrup
1 cup of baby shampoo,
1 cup of antiseptic mouthwash, and
1 cup of tobacco tea*
Mix all of the ingredients in a bucket, and pour into your 20 gallon hose-end sprayer. Apply to everything in your yard to the point or run-off every 3 weeks, in the morning, throughout the growing season."
"Q: How do I get those darned chipmunks to stay away from my garden?
A: Try sprinkling bloodmeal around the garden, or scatter dog or cat hair around the area. That should stop ‘em in their tracks. You might also want try my All-Purpose Pest Prevention Potion: 1 cup of ammonia, ½ cup of dishwashing liquid, 1/2 cup of human urine, and 1/4 cup of castor oil in your 20 gallon hose-end sprayer. Then fill up the balance of the sprayer jar with water, and you’re ready to go. Overspray any areas that need to be protected, so long as you steer clear of food crops. To protect your edibles, you’ll have to spray around the perimeter of your garden."
