Rob:

I do a little tying but mostly to form a fan shape which I like best. But other plants are a bush or an open vase. Usually by heading back hard at planting you can get shoots pointing where needed. This means there isn't much training needed.

When I do tie it's usually to the lip of the pot but sometimes to a stake stuck in the pot.

I was thinking open vase, but I'll have to look into fan shaping my peaches. I could pop a few holes in the pots with a drill and tie through them with some sisal to hold down branches.

Rob:

Fan shape is only because they line up in the greenhouse nicely in that shape. But basically I'm taking whatever shape the tree presents. If the initial branches form a fan that's good. But if they form any other shape that will work as well. Mine are small enough that shape doesn't really matter in terms of light distribution or anything else that might matter on a big tree.
