Here is an idea.
On any site that we are going to be offered to have a community food growing garden there will be some factors which are not ideal for food growing. A slope, shade, bad soil, overhanging trees, bad access,rabbits, etc etc.The Foundation House site shares many of these problems in different parts of the plot.
But in the real world of people's gardens and allotments these are the problems they have to deal with. None of the situations I have mentioned above would mean no food could be grown, it is just a matter of the careful design of that particular type of plot.
Maybe this is what we could do with a community food growing garden in Louth. We could demonstrate that it doesn't matter what your garden or growing space is like there is a way that it could be used to grow food. The plot could be divided up in relation to the type of issues that that area will present. A section under the trees, a section on the steepest slope, etc.
Then a food growing garden to suit those conditions could be built in that area so show people it is possible.
Just an idea...
