Success second time around with my snaps. Last year when I grew then I had gang potted seedlings closely then separated into clumps. I think they didn't like being transplanted or crowded. Plus the temps got warm quickly. This year I started earlier in January and did just a few seeds in individual jiffy pots. The kind of pot where you just plant the whole thing seedling pot and all into planter or ground. So no root trauma. Plus I put them out while it was still find because they can handle frost much like pansies.
