My feedback is that you need to turn your problem from being too many leaves, into a problem of not having enough leaves. My worms love wet leaves and I am adding to my bins 60 gallons of leaves every other week, along with 30 gallons of kitchen scraps.
I see four possible solutions: 1) restart the pile but smaller, more in line with your population size, 2) keep the pile the way it is but be patient and they will eventually catch up but it may take many months, 3) buy or gather more worms and add them to existing pile or, 4) you can dry then screen your entire pile to capture the castings that have been created so far (ooh, that's a lot of work).
I believe you should be able to start right up again as long as there is enough food and moisture and the right temperature in your bin. If what is in the bin looks like mostly finished castings then it would be best to start with a fresh batch of manure and moss. I believe the best tea is made from fresh castings.
My goal was to reduce the volume of waste we send to the landfill, to reduce nutrient loss from our property, and to create my own soil amendment for gardening.
The challenges in my area are keeping the bins moist enough (year round) and warm enough (in the winter= zone 5). I have two bins that are each about a cubic yard in size. I made them big so there would likely always be a warm, wet spot in the middle for them to migrate to if needed. The bins are made out of cedar fence wood with small (quarter-inch) gaps for air. If I had to it all over again, I would have made the gaps smaller, as I am still losing too much moisture.
In the winter, I have 3 feet of dry leaves above the worms, inside the bin, to provide insulation. I harvest the compost twice a year to minimize the disturbance to the worms, once in the spring and once in the fall. I feed them about 25 gallons of food scraps per week, plus all the trimmings and leaves from the yard. I would estimate about one-fifth of the food scraps are citrus.
I ferment the food waste for one week before putting in, and this seems to help a lot with the smell. I also cover each deposit with a thick layer of shredded leaves to cut back on fruit flies. Having a solid floor is a good idea, as roots from neighboring plants aggressively invade the bins.
I use a DIY, mechanical, rotary, two-stage screener to sift the castings to retain the worms and eggs. I spend about a half-hour a week adding material, and about 30 hours a year harvesting and sifting. I end up with about 3 cubic yards of finished product per year. Never quite sure how big my herd is, but I do know they are hard-workers.
I signed it. Besides the Farm Bill I think another good source of money could be Homeland Security. I recall hearing that a main theme of Homeland Security is to teach, train and encourage our citizenry to be resilient. What is more resilient than Permaculture?
I have had good luck processing kitchen scraps using red worm composting year round in zone 7a. My herd reside in two large (5'x5'x5') outdoor bins. I add water weekly to moisten the pile in the summer and insulate with a thick (3') layer of leaves during the winter. My family produces about 5 gallons of kitchen scraps per week, and we add in leaves from our yard and from neighbors yards in the fall. Last year I harvested about 60 gallons of finished compost.
A friend of mine who lives in the same area is looking to duplicate my operation but on a much larger scale (food scraps from restaurants), possibly needing to process 60 gallons of input per day! We will probably experiment with windrow-style composting, at first, rather than building a large number of bins.
Since we are in the design phase, I wanted to put the question to the permie community about what other functions we could stack with the composting operation. I would be interested in hearing ideas that have never been tried before as well as actual processes that some of you have tried or are currently using, and what worked well and what didn't work so well. This friend has some livestock (chickens, goats) so feel free to include them in your consideration.
