And slowly but surely, I'm converting the beautiful but highly labour-intensive flower gardens that my parents so lovingly created by the sweat of their brow, into mulched beds with a mix of perennials, shrubs and trees. It's true, they don't have the spectacular bursts of color but, except for a bit of hand picking weeds, they don't demand the attention and I rather like the less formal 'natural' look. Large shrub beds, and a solid refusal to fertilize, also keeps lawn care to a minimum. While we still have copious amounts of lawn (also planted by my parents), as long as I follow a few basic rules such as no chemical fertilizers and not cutting it too short -- the time is kept to a minimum.
When I walk through someone's yard or poke through a garden centre, my mind is always focused on ways which I can continue my hobby in a manner which is kind to the earth (and therefore to me) while keeping the maintenance to a minimum and the enjoyment to a maximum. Perhaps you're the same. If so, here's a few links for your reading pleasure.
