scompton,
If sprouted in the house, newly sprouted seeds (veggies or flowers) need to be hardened off before they are planted in the garden or they will burn.

Place them where they will receive morning sun for 1 week, then gradually give them more sun. If you want to plant them directly into the garden, you need to use plastic milk bottles to shade them a bit until they are established.

Below is a milk carton protecting my tomato plant against late frost and to harden them off. It is held in place by a dowel. The cut opening faces east for morning sun.
