Yes! Absolutely, Áine! au naturale is the way to go, at least, every once in a while.

I call it (at least, now I do... I just thought of it ;-)) "The Zen of Un-Gardening"

Because of this philosophy, I have a yard full of wild strawberries and clover (and therefore bunny rabbits and birdies) and a little magnolia tree that a bird donated... I think s/he carried the seeds over from the local public library which has a stand of magnolias by the entrance... If I pulled it up when it first sprouted (and I almost did, cause it looked so weedy) then I wouldn't have a future elegant centerpiece to my yard that it is now becoming...

Come late summer/autumn, you might want to try this little experiment with Un-Gardening: Plant-a-sock
