Rawsonville: Rowe's Produce Farm has an active Facebook page, and doesn't yet have details of when first harvest will be. Their strawberries survived earlier frost scares. No U-Pick raspberries this year. UPDATE: Rowe's will open for the season on June 8, berries $1.78 per pound.
Ida: Whittaker's Berry Farm (also on Facebook) is estimating first picking to start between June 10 and June 15, and notes that an average season is 18 days long. UPDATE: Whittaker's will open for the season on June 8. The price is $1.42/lb.
I'll update this post as the season gets closer.
