Hello all,
This year I've decided to grow more flowers from seed, I have started with carnations, aster, alyssum & hypoestes. I started them in a seed tray, most have germinated and they have 2/3 true leaves. They are on a south facing windowsil. What now? I could do with the space on the windowsil can I harden them off to take up residence in my unheated greenhouse? When will they require their own pot or can they stay in the tray til the risk of frost has gone and can be planted out, (I know that at least another 8 weeks) cheers ally
