Pruning grapes & fruit trees
Is there a training seminar showing you how to prune grape vines and fruit trees?
Linn County Iowa
I'm not aware of any pruning workshops in your area. However, the Linn County Extension Office would be the best place to check for county workshops or classes. The telephone number for the Linn County Extension Office is 319-377-9839.
The publication "Growing Grapes in the Home Garden" does have a section on pruning grapevines. The publication can be found at the following website.
Information on pruning fruit trees can be found at https://store.extension.iastate.edu/Product/pm780-pdf
