If your seedlings are small:
: Fill your container with soil or compost. Make a hole in the compost with your finger or a stick.
: If you have several seedlings growing closely together, separate them out by teasing out the roots. (Ask an adult to help if this is tricky).
: Holding the seedling by the leaf, pop it into the hole and cover the roots with some more soil or compost.
: Water well.
