Earlier this week, I took the jiffy pellets with the white coneflower seeds and put them in a different tray that’s on the heating pad and is still covered. That did the trick, and within seven days, many of them are sending out roots now.
The salvias are finally starting to grow more, so they are developing larger true leaves (not just the seed leaves, or whatever you call those first two that emerge from the seed and later drop off).
I moved the poppies off the heating pad, because they seem to like cooler temperatures.
The coreopsis plants are growing pretty well and looking healthy.
The cosmos plants haven’t grown as fast as they did the first week or two. They look OK, although a few look a little yellow. They might have gotten too much water.
