What a dilemma when you clear a green field site with a plan to create an educational garden and discover that the top soil is limited to max 30cms and the sub soil is solid clay.
But we want to build a cob wall around the field - yippeee we have more clay than we are likely to need.
But how should we approach soil improvement when we want to grow some delicious vegetables this year?
I am planning well rotted manure but what about the weeds if its not been well composted
