hi! I’m very proud to be growing lots of things from seed and bulb this year but I have a question about cosmos! Does each single seed turn into a big plant? Or should I have had 4 or 5 seeds in each pot to form a single plant? Also, the little plants haven’t grown much at all in the last week. They seem to be stuck how they appear in the photo! They shot up quick but then haven’t grown at all lately. I’ve had them indoors for a few weeks until now, when I’m putting them outside for most of the day. We’ve had virtually no direct sunlight for weeks!
