Green Fingers? Meet the Big Planters.
If you are part of a Gardening Club where space is at a premium why not consider investing in one or two Big Planters? They score highly on practicality and durablilty so they should provide decades of productive service to your club. Go low (600mm) or go higher (1 metre) and perhaps add some linking bench seating for when the hard work is done.
