Overhanging trees casting shade?

Some varieties unless in full sun such as my Chetsuseyama will turn from copper to green if not in full sun.

Thank you Fractal. It is in full sun but has been moved from one border to another. I have had it about 5 years but never seen the grren leaves on it before

When did you move it? These may be secondary growth leaves that are produced sometimes after a shock and can be green instead of purple/bronze etc from the off.

I only moved it about 6 weeks ago after I had the garden done. I also wondered if the soil could be contaminated with building dust sand etc

As long as you moved it with a large rootball it should be ok. Building dust shouldn't be a problem either unless it had a lot of lime in it. Building sand though not good for plants wouldn't turn the leaves green to my knowledge. Just give a really good soak once a week to keep the plant happy.

Thanks for your help. I am a very amateur gardener. Just teaching myself as I am going along but thoroughly enjoying it.

That is half the fun, the successes far outweigh any failures :-)
