I have just acquired an allotment & plan to have some raised beds as the soil is clay based.
I will be using scaffolding boards which are 9 inches wide, therefore if I sink them just one inch this leaves 8 inches in which to fill.
Q1 - Is it best to use a combination of top soil & pro grow or will it be ok to use just pro grow.
Q2 - As I will have 8 inches of hopefully good quality soil will I need to work the allotment soil at all & if so what will need to be done.
