Early Bloom in Blueberries

Michigan is the number one state in Highbush Blueberry Production . Most of the acreage is located in Southwest Michigan near the Lake Michigan shore. The sandy glacial soils and high water tables result in excellent blueberry soils with pHs in the 4.5 to 5.5 range. Over 20 varieties are grown in Michigan. The harvest season normally runs from early July through October. Unlike most other fruit crops in Michigan, most blueberry plantings are irrigated. While lowbush blueberry grows wild in Michigan there is little commercial production

Blueberry Information at MSU

MSU has a Blueberry Website Blueberry Facts this site has pest and disease control information. For current information, check out the MSU Fruit CAT Alert for current season's articles on blueberries and insect and disease control. This newsletter is produced weekly during the growing season and includes articles on fruit production as well as IPM practices and guidelines. A great deal of information is posted at the Van Buren County Blueberry Page.

Late pink bud is before the flowers open Blueberry Growth Stages used in the MSU Fruit CAT Alert. I have lots of pictures posted and linked to this file.

I have posted a factsheet from Dr. Rufus Isaacs on recognizing cranberry fruit worm and cherry fruit worm in blueberries. This is a PDF file and you will need Adobe Acrobat to read it.
