Within the first two days, the comfrey tea was looking dark brown, and not smelling at all. Great! I did it – or so I thought. “I’ll just let it go for a week – let it get really ‘good’.” Not such a great plan. After one week, it was smelling like a septic system gone awry. I removed it from the bubbler, cut it with ten parts water and fed several plants, including:
- One tomato plant – banana box garden(bbg) proper
- One tomato plant – bbg – extended (with wicking bed)
- One tomato plant – bbg – extended (with no wicking bed)
- One patty pan squash – bbg proper
- One box potatoes – bbg proper
- One brocolli – hugelkultur bed
- One patty pan squash – hugelkultur bed
These plants have similar ones next to them, so if there are any good or bad effects, it should show up within a couple of weeks. The rest of the swill went onto the compost heap. After a quick thunderstorm, there was no smell in the garden – thankfully!
Next experiment will be to use one quarter the amount of comfrey, and 1/2 the amount of water – the stone I have is about the size of a cherry, so there’s not a lot of oxygen getting through the mix. Anyone else have experience with comfrey composst tea?
