'Cos' of the compost

A little while ago I planted some Cos lettuce seedlings that I bought from Bunnings. It is amazing how much the one I planted in the pot with some compost has grown so much more than the one planted in the garden bed. That compost seems to be good stuff! I did lose two others planted in the pot thanks to a visiting cat. The photos don't clearly show the difference really but here they are anyway.
