Morning, everyone! I started my first tray the weekend of March 4th and things are progressing nicely! I started seeds for Petunia, Zinnia, Morning Glory, Cosmos, Holly Hock, Black-Eyed Susan, Cardinal Climber, as well as some herbs like cilantro, parsley and sweet basil. ( photo / image / picture from SylvieB's Garden ) The Morning Glory (first 7 pots on the right) has taken off in just 9 days! They are now about 3 inches tall. I believe the seed packet says to thin/transplant at 12" but that seems a bit tall and I would think they would fall over at that point! I bought larger Jiffy pots this past weekend but I'm wondering when is a good time to transplant these to those larger pots and how many should go in one pot? I believe I put about 5 seeds in each pot, but as I said, this was my first attempt so maybe that was too many...?
