How to prune damson 'merryweather'

Mid-summer (June–July) on established trees to minimise silver leaf infection risk; formative pruning in early spring for young trees. Aim for an open-centre (goblet) form. On established trees, remove the four Ds: dead, dying, diseased, and crossing branches. Shorten long leaders by up to a quarter. Always cut to a healthy outward-facing bud or branch junction. Paint large cuts with wound sealant.
