After a over a decade and hundreds of hours of tilling/weeding/watering/amending and still getting poor produce production, FINALLY we have had success !
Gardening at 7500 ft with a short 3.5 month growing season
Hope this helps someone in a similar climate
Please feel free to share recommendations, I surely don't know everything, but we finally found what works in our environment.
We had to can a bunch of garden produce, but the canned green beans even to this day are still bursting with flavor, and the best part of any meal. Crazy!
