Does a vegetable garden make financial sense?

Some say that one can save a good deal of money by growing one’s own vegetables. This may be possible, but certainly not easy. This is the first year we have attempted to grow a sizable vegetable garden of our own. We invested €250 in an old tractor and about another €300 on parts getting it going. We also purchased and old plough; this cost another €200. I know that these costs will be relatively small when spread over a longer period. We also bought a cover for our polytunnell, hinges for doors. Luckily our neighbour was able to supply the frame for the tunnell as part of a barter agreement. Smaller investments included, some garden tools and of course, the all important seeds!  We will try and keep track of our costs and maybe by next year, we may have a better idea as to the costs and savings. It is a real challenge to keep pests, particularly slugs and birds away from the corps, the garden demands our daily attention.
