Three weeks ago I bought a potted Ginkgo biloba from a local nursery, with strong green leaves. I've never looked after a Ginkgo before but I watered it every other day apart from the day we had heavy rain. It's been in a sunny spot and I've recently moved it into a part of the garden where it's shaded on one side.
This is how it looked the day I bought it:
And this is how the leaves look like now:
Almost every leaf is yellowing on the outside. I understand that one of the features of Ginkgo trees are their strong yellow leaves in the autumn but this seems a bit early.
I live in the south-east of England.
