I am growing my first flowers from seeds and am using the Jiffy seed starter kits from Wal-Mart.
I'm growing moss rose (using peat pellets) and a mixture of cut-flowers (mostly marigolds).

1st Photo - I planted the moss rose based on instructions from the seed packet (place on top of soil, keep moist). I used the peat pellets for these because they are so small.
They shot-up 1 inch in a couple of days ... literally! Now, (1 week later) many are falling over and dying. I've tried misting them often then allowing them to dry a little, putting them in the sun for a few hours but nothing seems to help. Any idea what I did wrong? Can I fix them or should I just start over?

2nd Photo - The cut-flower mix is doing great after a week but some seem to be falling over although they look healthy otherwise ... I think. Maybe I didn't plant them deep enough? I can't tell you which ones are which because they came from a bag of mixed seeds.
