Well, a few new ones are still coming up. I'm just trying to figure out if I did something wrong.
I put out three beds last fall. The main bed got a little more than a pound of seeds, and has so far yielded maybe 100 plants. A second bed is on the other side of a flooded creek, can't get to it. A third small bed, sort of a last minute thing, is doing better. I didn't cover the main bed with mulch, that may have been a factor, as the small bed got a leaf covering by default.
Notes for next fall: Answer this question completely. Put out a series of beds: one bare ground, one with mulch. Try rake and scatter, and use the precision seed planter (what I used last fall) on another, seedstick on another. So far the one conclusion I can reach is - for both bed and hillside plantings, bare ground is not good.
And I wonder if the heat/drought of last fall was an issue.
The 2YO roots I put out last fall have done great, evenly divided between 2 and 3 prong, and at least one 4 prong. Found one root that had been uncovered by erosion, just the bottom tip still in the ground, and it had put up a 2 pronger. Covered it up, it's doing well. I want seeds from that one, a tough little fellow.
And all the rain has the wild ginger, bloodroot and trillium really coming up. Got one part of the hillside that's thick with jack in the pulpit.
