Holy cow, Wendy - this one is expensive - $65 and higher! I grew tree Peonys back in Missouri and thought $30 was a lot for one plant. This one must be rare.

I don't have experience with what you're attempting so take my advice with a grain of salt. Hydroponics and organic gardening, at least traditionally, are at different ends of the spectrum. Hydroponics uses soluble fertilizer and inert media like bags of sawdust or rockwool - the nutrients are all measured and mixed accordingly. Organic gardening uses manure, compost, and soil - nature takes care of the rest. I think the way you propose may be more challenging than either growing organically or 'standard' hydroponic. You can try the hydroponics forum here. You can also test this out on one or a few plants so you can see how it works without investing too much. Here is a link that might be useful: Hydroponics

Hi Audrey! That sounds good. I'll take all the comfrey I can get. I want to grow a lot of it. It sounds like there are a lot of good uses for it. I don't plan on drinking it as a tea, however. I'm a little leery of doing that with herbs but it makes great healing pig fodder as well as garden fertilizer. I have really appreciated all that spurge. I have lots of space to fill. I spread it out in tiny pieces as an edging and am looking forward to seeing it filled out. I know what you mean about the oregano. I had it everywhere at our previous place too. Now I have mint in abundance all over this property! Want some mint? I'm happy to send you some blue flax seeds or I can save them for an exchange in the spring. Whatever you want to do is fine with me. If you want me to send them to you, you'll have to send me an email with your address.
