As a generalization, a mature plum will be larger than a mature peach, but the size difference isn't too great. If you don't choose a genetic dwarf tree, expect roughly a 10 foot mature height and width; potentially 12 to 15 feet for a standard-size variety. Based on pruning techniques, the tree's final size may be proportionately wider than tall.
All stone and pome fruit trees are high-maintenance, so the better the inherent disease resistance a variety has, the better to minimize the need for yearly preventative pesticide applications that help protect tree health and crop quality. You can explore our Growing Stone Fruits page for more information and a guide to typical pest and disease issues, which tend to be shared between peaches and plums since they are related. Be aware that both plums and peaches tend to bloom early in spring, and if we have a warm spell followed by a cold snap, that could freeze the flowers, damaging or killing them and preventing the tree from producing a harvest for that year.
