How much to grow

It might help people if they knew how experienced a gardener you are and how much land you have. If you are a newbie gardener as well as a newbie to the site then I would not recommend trying to be self sufficient in your first year but rather to grow what you like to eat and split the land you have into areas that can allow you to rotate crops. You will learn so much in your first year.
If however you are already an experienced gardener then the next question would be how much land you have to grow on. A standard size allotment is meant to allow someone to grow most of their veg for a family of 4 but I am not convinced. A better use might be to grow the expensive stuff or the stuff that tastes much better fresh than to try to grow everything you eat. Self sufficiency is an admirable aim but pretty difficult in practice. Use the search facility on the site to check for posts on this where much more experienced people than me have discussed this already - most of all enjoy your growing!
