I tested the 'dry' method of making liquid fertilizer last week and I'm sold. I used to soak the plant material in a bucket of water for a couple of weeks but that seems unnecessary. Just fit your container with a strainer at the bottom, leaving a gap underneath where the concentrated plant juice can store (see here @ 45:00).
This perforated container and drip pan setup doesn't actually require a strainer. However, I've rigged it up that way for test purposes. (I will be purchasing a large barrel with tap in future).
|5 gallon container with drainage at the bottom (remnant from hanging tomato era)|
|Spacers (in this case, bricks)|
|Rack/Strainer (in this case, 3 layers of chicken wire)|
|Shrunken plant material (initially packed to the rim)|
|Decomposing muck (underneath)|
|Drip pan (in this case, pie plate) |
(The barrel will have a tap)
|Concentrated plant juice|
This small stack produces 1/4 cup daily
Quick and simple. No wait, no stench. Use 4 tablespoons (60 ml) per watering can and Bob's your uncle.
