I have a beautiful salix integra which I am trying to grow into a tree, however it has four stems, how can I prune it back so it grows from one stem to resemble a trunk.

Agree with Derek never intended to be a tree as such.

There are two images of what it says is this variety on Google Images trained into a very small tree, but it must have been trained like that from the very beginning.

Not sure if I'm doing this correctly, but thank you for your answers. What a wonderful website

Hi, welcome to GoY, it will look a bit odd, but there's no way to do it, other than taking out the other 3 stems, this plant is a shrub, growing somewhere between 6 and 20 ft high, there's no way you can turn it into a tree, sorry, Derek.
