Just got this tip that Penn State Extension has its berry course available for free through April 30. Looks to me like you still need to register, but you won’t be charged. Terms and conditions say you can select up to 3 eligible extension courses to take for free with this offer. https://extension.psu.edu/growing-raspberries-and-blackberries-from-planting-to-harvest
Thanks for posting this!
They also have two free courses on orchard management
