Plums may have been one of the first fruits domesticated by humans and is considered a subgenus Prunus of the genus Prunus. The subgenus is distinguished from other subgenera such as peaches, cherries, bird cherries, etc.
Mature plum fruit may have a dusty-white waxy coating that gives them a glaucous appearance. This is a wax coating that is known as the “wax bloom”.
The commercially important plum trees are medium-sized, usually pruned to 5–6m height. The tree is of medium hardiness. Without pruning, the trees can reach 12m in height and spread across 10m.
They blossom in generally during Early Spring to Early Summer time, depending on cultivar.
Plums should be planted during the dormant season just before the new growth starts in late winter or early spring.
Plant plum trees in loamy, well-drained soil. Plums do not do well when planted in clay-heavy soils or in locations where their roots will be constantly wet.
Choose a planting location that receives full sun with at least 6 to 8 hours of good direct sunlight.
Space standard-size trees 3 – 6m apart.
Do your best to untangle roots without damaging roots, but if the root ball is particularly pot-bound, you can loosen it by scraping up and down the side
Dig a hole that’s a few centimeters deeper and wider than the spread of the root
Water the tree thoroughly as this helps the soil to settle around the roots. Keep the tree well watered for the first few weeks after planting.
