Boysenberry’s Uses

The berries can be eaten fresh off the vine or can be manufactured into jams and jellies, preserves, pie fillings, syrups, and wine. They are sometimes used in fruit salads or as a decorative edible topping to cheesecakes and tarts. Turned into a fruit sauce, boysenberries are a popular accompaniment to fowl, such as duck and goose. The boysenberry’s growing season is relatively short, typically occurring between early July and early August. Its shelf life is also short. The fruit can spoil if left for more than two or three days after picking. Washing ahead of time can shorten the life span of the fruit even more.

Threats to Boysenberries

A common threat to boysenberry harvests is the fungus botrytis, which infects many plants. The fungus thrives in moist conditions and can survive the winter months as sclerotia, evident as small, black lesions, or as mycelia, a thread-like growth, both of which can form on dead or decaying plant matter.

Boysenberry decline is a common term for Cercosporella rubi, a plant fungus that causes a disease known as rosette disease. Boysenberry decline can cause a symptom called witch’s broom, a plant deformity or disease that changes the structure of the plant, and can cause the production of double blossoms, which can lead to low yields. Cercosporella rubi is a problem exclusive to the southeastern United States.
