Anyone have a recipe for a "complete organic fertilizer"? COF is a self made mixture of organic materials a person can use on an area of garden that is not really big enough to justify doing a soil test on it. It is a complete mix with as many as 20 products mixed together in some compost, all of which is then spread on the garden and scratched in early in the season.

Here is a sample recipe. If you are growing in an area that is not big enough to merit a soil test you could use a “complete organic fertilizer” that would not be as good as balancing your soil but better than nothing. Here is one recipe that can be used to cover 100 square feet. It should be applied to the soil annually in the fall and better yet in the early spring and mixed into the top 3 inches of soil using a rake or digging fork.

2 pounds feather meal
2 pounds fish meal
3 pounds soft rock phosphate
1 pound kelp meal
1 ½ pounds agricultural limestone
1 ½ pounds gypsum
1/3 cup potassium sulfate
1 teaspoon borax
1 ½ teaspoons zinc sulfate
2 teaspoons manganese sulfate
1 teaspoon copper sulfate

This will weigh around 11 pounds and should be mixed into some compost, spread on top of the soil and then dug into the top 3 inches of soil using a digging fork or rake.

Any thought?

Thanks for the info Marv. I currently have seven of those listed above to add into the soil shortly. I don't have borax yet. Does that add boron?

Do a search for "Subcool's Super Soil"... very similar mix meant to be for long-term fertility when growing in pots. I would imagine it would be a great mix for the winter challenge, or a great top-dress mid-season. Disclaimer... mix was developed for cannabis, but don't let it scare you off, it's legit.

Borax is a source for Boron. Be careful with how much you add.
