Good morning everyone. I had a problem with starting my snapdragon seeds this spring. It was my first time with snaps. I sowed them pretty thick (hard not to) so got them transplanted into 4 inch pots-3-4 little clumps of plants to each pot. but then they just kind of sat there and eventually died. They had almost no roots. I started the seed on grow mats in my greenhouse. Anyone have any Ideas on why that happened? They sprouted like gangbusters but never grew much root.
