When to transplant Seedlings?
I’m in zone 6a, (New England) and I started these seeds in mid February, outdoors in covered trays.
I think they started popping up a little over a month ago. I’m worried the trays are too small and that’s why they aren’t growing more yet.
All of the swamp milkweed seeds failed except one (first pic) and it seems to have another leaf coming out of the middle. The butterfly weed seeds that I harvested myself did very well at first but some have since wilted and they don’t seem to be making progress after I clipped the extra seedlings. (Second pic - before I clipped one of them).
I had read that you should wait until they have multiple “true leaves” before transplanting, but I’m worried that they just won’t grow more in these tiny cells?
So do I wait for more growth or transplant now? How much longer to wait?
