I was amazed by how big Mr Gavin's "garden" was - the pics on the TV didn't do it justice. It was enormous. And it also highlighted what can be done with a bit of imagination, some compost and some plants, in pots and containers, 100 foot off the ground. I often think how little imagination some of us Brits have when it comes to high rise living, wheras on the continent, if you walk or drive past a high rise block of flats or apartments, practically every balcony has a pot of something growing in it, even if its just a geranium. If only some of all these new modern city developments that have become so predominant in all our city's and towns took inspiration from Mr Gavin's garden, the world would be a much greener and pleasant place. Perhaps the developers of city apartment blocks should be made to install window boxes and provide at least on plant, a a bag of compost to all new residents to get them going.
