Just been reading about an initiative in Texas where they are looking to introduce edibles into Front Gardens - what a great idea. So much better than paving over the front garden. Good for community relationships, good for the environment and they look so much prettier too. We turned our front garden (or part of it) over into a Kitchen Garden area some 4 years back and have never regretted it. I am often out in the front garden tending my veg and get time to say high to all our passing neighbours.
