Q.Is There A Place That Will Take My Tree Saplings?
My beautiful London Plane tree produces many seedlings which grow into saplings very quickly. I usually put these in my green bin which I hate doing but I only have room for one London Plane tree in my small back garden. I would love to donate them but do not know who could use them. Can you help with suggestions, please?

I would visit your local nurseries, garden centers, or any of the universities in your country. There may be a school or local plant place that could use a few extras.
Or, depending on the laws in your area, you could attempt to grow them in containers and sell them!
