Acer japonicum aconitifolium - it seems it will soon cover my garden, lol.

chop it lol yes it filling out looks great there :)

Thank you, Mark .-)

You could prune it Katarina if you wanted to change the shape of the tree. I usually prune mine back in the winter.

I read that it s not recommended...???

perhaps it's a different type to mine then Katarina. The winter has affected some of my acers and I've had to cut out some of the dead wood.
