I’ve been using blood meal and bone meal tea on my garden for years.
It‘s simple.
I leave a 1/4 cup measure outside all summer. I scoop 1/4 cup of compost and 1/4 cup of either bone meal or blood meal into a 2 gallon watering can.
Then, I fill to the top with water.
It does not clump or float on the top.
The microbes in the compost quickly proliferate in the tea, hopefully helping to release the nutrients in the adjuncts. When i’m ready to feed, I simply stir vigorously. I give a little shot to everything - tomatoes, eggplant, marigolds - whatever.
So, does it stay in perfect suspension in the water? Of course not. A bunch of it falls to the bottom before I’m finished feeding. Who cares? It’s so mild that my plants never get burned.
Instead, they turn deep green and thrive.
How do I know?
I did an experiment last year. I have four containers of marigolds each summer. I fed three with the tea. The fourth I did not. The one that did not drink the tea did ok. But, the plants were much smaller and less deep green and had fewer blooms. The three that drank the tea had leaves that looked like a deep and dark green.
