Rare Fruit Alert

Finding the Shiro Plum at your local grocer is an effort in futility. This rare little yellow gem can sometimes be seen at small fruit and veggie stands, but they are gobbled up in a flash. The slightly translucent flesh and vibrant color make these plums irresistible for curious foodies.

Golden yellow, sweet and so juicy, they are typically not planted in large commercial orchards because of their short shelf life. If you are lucky, you may find them at local farmers markets when they are in season.

Therefore, the Shiro Plum tree has found its home in the orchards of home gardeners who can harvest and enjoy without worrying about the fruit’s transportation requirements. Isn’t that why we plant unusually varieties, because they taste so amazing and are not bred to ripen during the transportation process. The best way to enjoy these rare little jewels is to plant a tree or two in your own backyard. Besides, isn’t it the best when you can pick and enjoy the eating your home-grown fruit fresh from the tree?

The Shiro Japanese Plum is a great addition to your home orchard. They are a consistent and prolific bearer. Home gardeners have recorded Shiro Plum Trees as old as 40 years and still going strong. 

History Of The Shiro Japanese Plum Tree

Classified as a Japanese or Asian plum, the Shiro Plum, surprising, was developed in the United States. The plum is product of crossing for distinct varieties: the Apricot Plum, the Japanese Plum, the Cherry Plum, and the Munson Plum. It is believed to be a cultivar developed by famed plum horticulturist Luther Burbank, Shiro plums were first introduced to the American Public in 1899, and they have been a major hit with home gardeners ever since.

The fruit is classified as a clingstone. It does require a bit of work to remove the pit, but it is well worth the effort.

Pruning And Thinning

Pruning

The Shiro Japanese Plum has an unruly, low growing and spreading habitat. At maturity, it can reach heights between 12 and 18 feet and a mature spread of 12 to 15 feet. 

Late winter is the best time for reigning in this plum tree’s spreading habitat. Pruning for size and shape along with removing cross branches is accomplished easily and will improve the tree’s fruit production and life span.

Thinning

The plum is a prolific producer with bunches of fruit running along the branches. Thinning the immature, green fruit when they are just forming will help produce a healthy crop that has room to grow on the branch. 

Plum Tree Diseases

In general, these plum trees are very hardy.The first line of defense in protecting your plum trees from disease is to prune away any branches that show signs of decay and disease. Removing broken and damaged branches is a key to successfully keeping your plum tree healthy.

Bacterial canker is one disease that can damage plum tree trunks and branches. If your tree shows signs of amber colored sap coming from the trunk, you may have bacterial canker. Spraying with copper in the fall and early spring will help control the situation. Try Bonide 811 Copper Fungicide to help get this nuisance disease under control.
