renewal pruning of an established apple tree, variety Sunset, a 20 year old tree on MM106 rootstock. It was trained a an open centre dwarf bush, currently somewhat overgrown, hence the slightly more aggressive than usual pruning. i will return to this tree later i the year to show what effect pruning has had on it. I may leave another one nearby unpruned for compare and contrast. NB this is a FINE tooth Silky Gomtaro 300mm pruning saw, the one I recommend (no financial interest).
