i have put comfrey and nettles in the same container 210 litres of it, all fermenting down lovely. Have made a smaller tub of the same and been using it as a feed and everything is loving it!as for chemical makeup etc, be silly sending off for a lab test as every batch made wud be different, unless you are going to weigh everythingwhy not make it and use it, it aint gonna kill anything is it?
Well ... my tuppence worth ... I used nettle "tea" a few weeks ago for the first time. I'd read that it's "good" (or is that bad) for blackfly, so sprayed it over my nasturtiums ... flowers for the bees, leaves for me ... and behold, no blackfly !So onto the next test. My Mustard Spinach had had problems with little white grubs eating the roots, unless caught at the first sign of wilting, dug up and "dealt with", the plant died. A good "slosh" of nettle tea diluted at 10:1 and no wilting Spinach since.Not scientific, I know, and quite possibly coincidental, but nothing's died, it's all looking very healthy, I'm still here to talk about it, and it didn't cost anything ... gotta be worth a try ;)As for mixing different types of leaves, I can't see a problem, you're only copying the sort of thing that happens in the compost heap, all sorts of stuff rotting down together. The net result won't be any more concentrated than with just one type of leaf, as you can only put so many leaves in a container before covering them with water. I don't have ruhbarb or comfrey so I can't do any tests, but I'd have no reservations about doing so if they were available. It's not as if you're making some sort of super-concentrated acid, just the liquor from a few fermented leaves that you're going to dilute anyway ... go for it !
the problem is you dont know the nutrient levels, and you dont know the nutrient balance or the pH
My very unofficial conclusion was it was better than nothing but compost or manure is better
Quotethe problem is you dont know the nutrient levels, and you dont know the nutrient balance or the pHWell, that's a bit of a red herring, isn't it. We're looking at a dilute fertilizer made from the sort of components that would be normally used to mulch the soil once composted ... how many people actually investigate the nutrient levels and pH levels of the layer of rotting vegetable matter they've just spread all over their plot, much less worry about it?
Any chance of an analysis of nettle or comfrey tea? It would be fascinating..
