A couple of months back I saw a few maple trees growing in my garden. I have enough large trees in my garden and don't need any more. So I transplanted them into a few large pots. Fast forward 6 months, I now find them every where, on steps, cracks, next to the fence! I haven't got the heart to pull them up like weeds, so I've been putting them in little pots. There are around 80 of them and that's just the ones I noticed!! I've asked for suggestions on the Oz forum. Meanwhile I'm also trying my hand at bonsai.
