Your impatiens are beautiful, Emily.
Impatiens are so readily available here that I'd just as soon buy the plants. But last year I searched everywhere for 1 inch cells and couldn't find them. They were all 2" cells. I stuffed those through the holes in my Bloommaster pots, (about 1" holes) and eventually they did recover. But the roots were messed up enough that it took a while. I want some skinny cells, that's the only reason I'm going to start some from seeds.
