We have a small courtyard garden with most things in pots or in the very small raised borders. It's all very nice and everything just re-appears each year... very boring but low maintenance.It is also north facing and only gets part sun or about 4 months.
After watching all these programs about growing your own etc. we were inspired to tear out all the nice shrubs and replace them with a couple of bags of manure..!
Last January most of the borders were stripped ... our borders vary from 12'' to a massive 16'' and are raised 8''above the ground by using exterior timber 100x50 mm.
Last year was our first attempt at growing anything edible... In this first raised bed we put in 16 lettuce..welsh onions..fennel...marjorahm...mint.. corriander...rosemary sage and chives... In the pots in front were peppers.

We could'nt eat the lettuce fast enough and ended up giving it away and everything else grew really well. In the other borders we grew tomatoes, cucumbers,courgettes, broad beans and then runner beans. None of these borders were more than 12'' across.
So yes you can grow in a limited space ... take it from a absolute begginer
By the weekend I am removing any shrubs we have kept and planning next years crop.
