Got gardening questions? You can ask the Almanacbut you should also know about your own state’s cooperative extension service. They have local experts who provide on-the-ground advice with tricky insect problems, the best varieties to plant in your area, and more! Here’ a list of cooperative extension offices by state.
What is a Cooperative Extension?
In 1914, the U.S. Department of Agriculture partnered with a nationwide network of universities to create a system of “extension” services. The goal of these services was to provide farmers across the country with advice from local experts regarding all things agriculture and farming.
The program was a huge success, and today, there are extension services in all 50 states (though some are not associated with the USDA). Extension services routinely put on community events, hold lectures and courses, and answer gardening and farming questions from locals. Typically, an extension service has a “home base” located at a prominent university in the state, but will often have a series of county offices, too.
Contact your state’s extension service (sometimes called “cooperative extension” services) for advice on anything from combating local pests to choosing plant varieties suitable for your area. Extension services are also the place to turn to to get your garden soil tested (usually for a small fee), enroll in a Master Gardener program, or get your child involved in a 4-H club.

California link for COOPERATIVE EXTENSION not working
could you please send me a link or help me find my local Cooperative so I can see about getting my soil tested. Thank you so much!
I am new to all this and want to start from the 'ground' up! :-)
California extension
Hi Dena, Happy to help. The link was on their home page but not easy to find so we updated the link to this: https://ucanr.edu/About/Locations/ You will see a map and can select your area. California is very organized and has an extensive and fantastic cooperative extension service. All the best! Your OFA editors.
Dead Tree
My Plum tree went first and the Peach tree, while still producing, and dying also. I treated for borers, and New Lovely branches have come out of the old dying tree. Should I let them grow. Or Cut them off propagate and start new. If start new, when do I do that.
