Growing and eating your own vegetables is such a rewarding thing. Whatever space you have, you can grow something, no matter how small it may be. It could be simple like some fresh herbs on a window sill or a tomato plant on a patio.
Homegrown veg tastes so good, much better than shop bought veg which sometimes is flown in from the other side of the world. If you haven’t the space (or the inclination!) try then to find local produce, it doesn’t have to cost the earth, and will generally be in season.
