I am going to make my wife a large raised bed for her salad plants
as she
has trouble bending,but still likes to potter in the garden.This
will be
very simply,a box on legs.Firstly do I line It with plastic

Optional

and secondly do I need to drill holes for drainage?

Yes

As a matter of interest I got the idea
from an excellent magazine called Kitchen Garden I have just
dicovered.

Maybe you could use those plastic planters instead ?
