I'm very excited to see how much interest there is here on permies about farmer–scale
permaculture. I really feel like this is a central challenge for our movement in this period of history. Those of you with already established farms can easily transition using some simple techniques. You can start to lay out contour or key line strips of perennials on your farm, right between your annuals or in the middle of your hayfields and pastures, as long as they do not interfere with your machinery access needs. Why not plant a contour strip of Badgersett hazelnuts or false indigo shrubs? What perennial crops are suited to your region, of interest to you, and seem to have potential to integrate with the other aspects of your operation on a production, processing, and marketing level? How can livestock be used to tie the pieces of your farm together more tightly and to substitute for labor, fossil fuel, and machinery?
As for fall planting I guess I've covered this some in other threads. Here in Massachusetts I mostly spring plant when things are still dormant. I have almost universal success at that time of year. I do some plantings at other times of year like anybody because sometimes things just have to get done when you have the moment free. Tough
natives and species which are very reliable in your climate are probably a better bet than marginal or pampered crops.
There are a number of things that set seed this time of year that work best if you sow fresh seed in a flat of potting soil (or on a patch of bare ground) and allow the winter to cold stratify the seed. I have found that everything in the parsley family loves this kind of treatment, as do most of the legumes. Obviously many nuts want to be planted from seed this time of year as well, as do fruits like persimmon and pawpaw. But again, for moving things to their final location in my
experience (please post yours) early spring is best. Maybe in fall I'm just not thinking about planting because I'm too busy eating fruits and nuts.
