Oriental Bittersweet: Weekly Wednesday
This week’s weekly Wednesday post is from council member, David Carmichael. David is a Landscape Technician with PEI’s Department of Agriculture and Forestry.
The images below are of Oriental Bittersweet (Celastris orbiculatis), which I came across while delivering upon a Forest Pest survey project for PEI. The site is located Eastern PEI and covers quite an extensive area.
Be sure to click the photos for a closer look and more information!
Management of Oriental Bittersweet:
Option 1: Regular cutting back of vines and not allowing regeneration or photosynthesis to occur for continued sustenance. Over a great period of time, if this practice is maintained, there may be a chance of eradication with gradual depletion of carbohydrate reserves. Note, often when vigorous plants are cut back, asexual reproduction is encouraged.
Option 2: Another option is chemical control. The PEIISC does not offer information on chemical control methods, however information is available on various websites. If chemical control is used, product labels should be strictly followed and considerations for possible environmental damage should be taken into account. Herbicide is prohibited around wetland environments in PEI.
Finally, avoid sharing plants with friends and be cautious of moving soils from areas populated with Oriental Bittersweet.
