Thanks for the great topic. I know some may disagree with my observations and they may be right, but it depends on what age you are getting started. I started at 50 and began by hand, ie shovel and hoe for a 3/4 acre garden. The first thing I did was to put my long term stuff in, such as fruit trees, nut trees, berry patches, grapes, asparagus patch so they could all work on growing towards producing fruit. Expensive? Yes, but some nurseries sell bare root plants for 1/4 the price. I enjoyed the book by Solomon, "Gardening When It Counts" as it helps guide you away from planting like a mechanized farmer towards plaiting like a gardener. By the way, I did the same as you, I bought books on canning and preserving, dehydrating and fermenting, managing fruit orchards, berry bushes and nut trees. So, for a bunch of stuff you can haul in a van to your new life post children rearing, if it ever really ends
buy some quality shovels like the Fiskars Worlds Best Shovel. I like the Hoes at Easy Diggin site. Greg is a great guy. If you want to start canning then look into a water bath and a pressure canner and some mason jars. I wasn't sure I was going to "can" vegetables then, in my first year I ended up purchasing and canning over 600 jars! From strawberry jam to tomatoes, green beans, salsa, spaghetti sauce, I mean lot's of spaghetti sauce, beets, pickles, relishes. I slept the entire fall!
, but if not there are other methods which I am learning more about, like fermenting, and dehydrating. Fermentation is incredible! Live fermented food is helpful for RA too! Sites like Wildfermentation where they have forums to read and learn and ask questions are priceless! Get to know your extension service telephone number too! They may be helpful in guiding you to an area of where you plan to relocate that has excellent soil. I am happy for you in your "planning stages" that is a very exciting phase, as well as the first few years, then it becomes a comfortable, familiar way of life which is priceless! Oh and right before you make your move buy some seed kits. My first garden was essentially planting everything In my seed kit, 43 different veggies and man was it a blast! Oh and look into printouts on the interned for how to save seed.
