How to prune malus 'royalty'

Late winter while fully dormant, before bud break (typically February–early March). Remove crossing branches, vertical water sprouts, and any dead or diseased wood to create an open-centred crown. Sterilise tools with 70% isopropyl alcohol, especially when cutting diseased wood. Keep individual cuts small.
