I don’t mind buying the occasional organic fertilizer to improve the health of my garden.
But I’m also a big fan of making a homemade fertilizer for plants.
There are a bunch of possibilities, but today I want to keep it simple with 2 homemade fertilizers everyone can “make”…
Yes, for real! Urine is an excellent homemade fertilizer for plants and soil.
It’s amazing how many nutrients we flush down the toilet every day.
And while we all know that poop, aka manure, can have soil-building benefits, an average pee contains something like 11g nitrogen, 1g phosphorus and 2.5g potassium, give or take of course.
So it’s a great homemade nitrogen fertilizer, but it also has the P and the K and no doubt some trace minerals, too.
If you’re healthy, there’s nothing toxic about it, though the smell may keep deer and other animals away.
Of course it’s easier for guys to sprinkle the garden directly than for women.
Cultural norms may be shifting but it’s probably still considered a bit odd to whip down your britches and squat right in your backyard, at least in the suburbs.
That’s why it’s nice if you have a compost pile in a hidden spot, because that’s the best place to do your business.
Or you can pee in the garden, too, which I often do. Just make sure you don’t pee right on your plants – ever notice how certain shrubs or patches of grass in dog parks turn yellow and die? It’s not a great homemade lawn fertilizer, that’s for sure – unless you dilute it first.
You can pee in a bottle or bucket, dilute it 20:1 with water, and then feed the plants or your lawn directly.
Here’s another homemade fertilizer for plants that everyone can do as long as you have some weeds or cover crops or even grass clippings.
Take any combination of herbaceous plants, put them in a container, fill with water, and cover with a fairly air-tight lid.
Leave it for a few days to a couple of weeks or months, and you have a herbal tea.
Especially if you leave it for long enough that the bad smell mostly goes away, the resulting brew will contain many nutrients and beneficial microbes from the plants.
This will be most effective with plants that are nutrient accumulators, like comfrey, yarrow, or stinging nettle, but all plants contain nutrients.
And some plants such as horsetail or chamomile have specific properties that repel pests or fight pathogens, so they’re nice if you happen to have them.
But I often just use clover and weeds and some grass clippings for this homemade garden fertilizer. Nice to keep it simple.
Any question about this? Any homemade fertilizer recipes of your own you’d like to add? Let me know below.
