Hi Daniel, thanks so much for your interest in the Master Gardener program! It is my understanding that there will not be a Master Gardener training in Josephine County in 2025. You will likely need to connect with an adjacent county.
I suggest you connect with either Logan Bennett in Douglas County, or Grace Florjancic  in Jackson County- both of them are awesome. Here's links to the contact info:

I hope you find this helpful, and thanks again for your interest in the Master Gardeners.
Have a great day, Nicole
