We, too, are trying to adhere to earth-friendly principles in our garden. Among these are:
Composting everything possible, both from the garden and from the household, here are my heaps and bins (click any photo to enlarge):
No pesticides of any kind, no chemical fertilizers. I wrote an earlier post on my attempt to deal with slugs in an earth-friendly way.
Collecting rain for watering. On the left-hand corner of our allotment cottage you can see one of the blue rain barrels fed by the roof:
Encouraging wildlife to feel at home in the garden. In the spring we will be putting up a wild bee "hotel" to provide a home for these endangered species, with the added benefit of pollination. Here's our model, purchased from a workshop employing the disabled (photo taken from their website):

Purchasing cut flowers from Fairtrade dealers. My last post was on this subject if you're interested. I'm really pleased with the Fairtrade roses I purchased for Valentine's Day. Not only were they grown under earth-friendly (and humane) conditions, they simply last and last. On the left you can see the roses when I bought them on Feb. 13, on the right the way they look today, 5 days later and still going strong, opening up beautifully.
Happy Earth Day everyone!
