tiny trees (Builth Wells)

My garden's full of tiny self set trees. Unusually, most are hornbeams (which mature will be 60ft high); there's some holly, oak, bird cherry (and quite a few western red cedar). Most are a couple of inches high. I can't leave them where they've come up, but it's such a shame to tear out a small forest.
Please, come and rootle them out. I can't kneel down, so you'll have to do that.
