I'm a seasoned gardener, but I've only ever bought 2 trees.
I'm sick of trying and failing to achieve shade in an area of paving. So I've decided I want a tree, in a pot. I reckon one that grows to 4 metres, and is happy in a pot. It needs to provide shade, so needs to spread outwards too. It needs to be wind proof as I'm in a very windy spot, in the north. I LOVE weeping willows but the dwarf variety I've found doesn't grow tall enough. Any suggestions would be most appreciated.
