Just a point!
How do you get the seedlings out?
With difficulty I would have thought, unless there is still a bit of the roman candle still in it. ::)
Couldn't resist that! ;D
Tee Gee,
you just leave them in the ground to rot away....
I do it like that with toilet roll inserts and sunflowers etc...

What about homes for insects etc.
Fireworks are full of heavy metals. That's what makes the pretty colors. So I would say: don't use for either food or insects.
I agree with Martin, do not use old firework outers.
