The blues are changing their tune

摘要

Like most blueberry growers, Jeff and Terri Weijohn of Blueberry Hill Berries have the bulk of their acreage in the Duke variety, the quiet workhorse of an industry that has seen unprecedented growth over the past 25 years.But also like most blueberry growers, they are trying new varieties, looking for something that might ripen later and appeal to wholesale customers as fruit begins to fetch plateauing prices. The Weijohns have several test rows of newcomers such as LastCall, Calypso and Clockwork at their Wapato, Washington, farm.
