How to prune marjorie's seedling plum

Mid to late summer (July–August, UK/US) after the main flush of growth and once harvesting is complete. Cut out dead, diseased, or crossing wood back to healthy tissue. Reduce long leaders by one-quarter to an outward shoot, and remove any congested upright growth to maintain an open goblet shape. Seal cuts larger than 2 cm diameter.

It crops heavily so also benefits from fruit thinning in June. Avoid all pruning between October and March when silver-leaf and bacterial canker spores are most active.
