I have two stinging nettle plants but they aren't growing hardly at all. I guess I made the mistake of planting the well rooted cuttings in 3 gallon pots instead of 1 gallons to start. The tea is very sweet. Such a joy to drink it. I made the mistake of trying to eat the leaves after I made the tea. Big mistake. Nothing like stinging tongue. Thank God it only lasted a few minutes. I hope I will have some to share next year. I don't know how to make it grow any faster in pots.

FINALLY got around to starting the process... That darn "life" thing can be time consuming sometimes! I've set up seven methods to trial in hopes of planting for this season, as well as some more long-term fallbacks. Axed the medium idea and stuck with paper towels or water, just to remove the variable of potential soil issues. Found some allium and cleome seeds collected from last year as well, so they've been added to the experiment. Not near as many as I have rudbekia, so the results won't be statistically sound, but I figure the more the merrier! Did a float test to separate out the good from the bad, which ended up doubling as an overnight soak. At room temperature, we have method #1: submersion in water with daily water changes, #2 submersion in water, no water changes, and #3 the traditional damp paper towel in a zippie bag. In the fridge we have the same three - #4 water, #5 water changed daily, and #6 damp towel in a zippie. There is also a container in for the long haul to do the normal three-month chill period. The one I have most hopes for positive short-term results is #7, a damp towel in zippie that will be swapped between the fridge and freezer every 24 hours. Seems to me the most accurate recreation of the required environmental factors. I still have nearly 1/4 cup of dried rudbekia seed left, and used at least that much setting up the trials. Considering tossing a handful along the woodline to fend for themselves. Plan on doing the same with the "floaters" that were culled from the experiment, because it seems whenever I discard bad seed, they always sprout in the compost heap, just to spite me.

you might want to get a copy of dirrs manual on Woody Plant Propagation ..... its the bible of such ... perhaps your local library can order it in.. if they dont have it.. so you can review it before purchase .... though i see at the link ... that the price has fallen significantly .... one of the problems with the WWW is the lack of focus ...aka.. to much info .. often seemingly contradictory .... ken https://duckduckgo.com/?q=dirrs+manual+on+propagation&t=ffcm&ia=products

I agree. And as soon as you 'see' new ones, cut them off. Mine do not seem to regrow after I pull them out. Because they sometimes grow in unusual places, I suspect the birds are also helping propagate them. They eat the seeds and deposit them elsewhere for example. At first, I did not have any ROSs and then a few sprouted. The neighbors do not have any ROSs so birds may have delivered them. I finally added some ROSs that were sterile and those performed as expected.
