Three types of plum are commonly grown in Utah: European, Japanese and American species. These species vary in where they are successfully grown and for what the fruit will be used for. Plums ripen in late summer to early fall, dependent on cultivar.
Three types of plum are commonly grown in Utah: European, Japanese and American species. Japanese and European plums grow in tree form while American plums grow either in tree or shrub form, depending on the cultivar. Even though Japanese and American plums are more susceptible to frost damage than European plums, they produce profuse amounts of blossoms and a partial crop is generally obtained.
Plums grow in most Utah soils as long as soil drainage is sufficient. However, soil testing can help determine the appropriate amendments to add to a site before planting. Apply any deficient nutrients as indicated from soil tests and till into the soil.
Plums, like peaches and apricots, have little tolerance of wet and heavy soils and will get root-rotting diseases easily in such conditions, especially when irrigation is not carefully managed. Plums are somewhat prone to iron chlorosis in the alkaline soils of Utah. Overwatering will significantly increase the risk of chlorosis and general tree decline as a result. Deep, infrequent irrigation and use of EDDHA chelated iron may help considerably.
