Once again Ken was the only one to bring a tree, this nice Scots Pine, which he thought needs to be repotted.
At first glance it looks like the tree is being pushed out of the pot by the roots, but on closer inspection it was just the moss growing quite thick on the surface of the compost.
We removed the moss and had a look at the compost which seems to be breaking down quite a lot. so it will be repotted when the weather is right.
Sorry, no after photo.
