Priscilla,
I have read most of your posts and I have to say that you have come a long ways in a short time! Congratulations!
Judging from your pictures, you have some challenging conditions with which to work. I started my own permaculture journey a couple of years ago starting with comfrey. At the moment I am focused on woodchips and fungi (stropharia to be specific). I am really focusing on making all my garden beds raised beds filled with mushroom
compost made from my own land. My ultimate goal is to never need any fertility that is purchased or originates from outside my own land.
With this in mind and given the substance of your previous posts, may I suggest that you try planting either a cover crop or a woody material that can be made into woodchips? The latter will take longer, but the former can yield results in the first year or two.
Cover crops can do wonders for your soil fertility. It looks like your ground is dry. Cover crops can really help soil hold onto precious moisture. They can fix nitrogen and really help with other nutrients.
Woodchips are great for topping garden soil, encourage fungi (the good kind) and can also save/regulate soil moisture.
These are just a few of my thoughts for you. You have an impressive array of accomplishments and I think that you are laboring under a goal similar to mine—to make yourself fertility independent. If this is indeed the case, then these are just a couple of options that may help.
Please keep us updated on your progress. You have some really great posts and I wish you success.
I hope this suggestions are helpful,
Eric
