Green Cone Composter
Over the years, I have had several compost piles of assorted shapes, sizes, and configurations. The first one, when I was much younger, was a super-duper one that Husband/Best Friend/Chief Photographer made for me with large, heavy, wooden pallets made of strong oak wood. There were three bins lined up side-by-side. Two were one pallet square, but the Number One bin was larger, because at first there is a greater amount of organic material which gradually breaks down and shrinks smaller and smaller.
He wired them all together with plastic-coated clothesline wire. In order to make the first bin largest of the three, he made the end wall with two pallets instead of one. It buckled or budged out at the side, but the front edge of the last pallet came back toward the front which was just one pallet wide. I could loosen the wire holding the front pallet, swing it out of the way and pull all that pile out, work it over and toss it back in to give it a good aeration and chopping.
After a few turnings, it went into the middle bin, because by then the volume was less, and because that bin was smaller it would be full. Each time I turned and stirred the material, it was given a new dose of oxygen, and the particles were bruised, broken, and smashed making it easier for bacteria to infiltrate the cells, all of which enabled the fungi, bacteria, and creepy crawlies to multiply and work away happily. In the meanwhile, bin Number One was vacant again and ready to start receiving new trimmings and pullings plus anything else that came available.
Each time I turned the contents of bin Number Two (the middle bin), the volume of material decreased markedly. Finally, it was transferred to bin Number Three where it was allowed to sit until I was ready to use it.
While it was waiting it would break down a little more, but mostly it was finished and cooled down. Earth Worms moved into it and contributed their processing. They were the largest, fattest earthworms you ever saw, and husky, strong, long night-crawlers that looked almost like small snakes. Rolly-pollies, pill bugs, sow bugs (whatever you want to call them), did the same. I removed the compost with my hands, because I did not want to injure them with metal tools. They were my helpers.
I tried to keep all three bins covered to prevent nutrients from being leached out. Smelling like fresh mushrooms, or a wood on a rainy day, the finished product was a mix of fine and coarse material. I could use it as it was, or sift it and separate the two qualities.
Early on, I realized that it was dangerous to breath the air full of spores as the compost was tossed about. I could tell I was getting an allergic reaction to it, so face masks became part of my garden paraphernalia.
Early spring or late winter one year, I discovered a lovely butterfly on one of the pallet walls. I had never seen one like that before. I identified it by looking in a book and learned that it was the Mourning Cloak butterfly, and that they are, frequently, the first to appear in early spring. Sometimes they hibernate in a protected spot until spring sunshine warms them; then they can move. I think it had hibernated somewhere in all that compost bin contraption. When I found it, the butterfly had walked into the sunshine and was sitting there taking a sunbath and collecting solar warmth for its whatever they have in the place of bones.
A few feet from the bins I planted two or three (I forget which.) McDonald rhubarb plants. As Dr. Spock's book had been my guide for caring for our babies, Organic Gardening Magazine was my guide for caring for my garden. I followed their instructions faithfully. Their article about growing rhubarb said to mulch it twice a year with compost. So, that is what they got, good homemade compost. They grew huge and delicious. (Note: I did not put rhubarb leaves in the compost pile, because of the oxalic acid crystals they contain. I did not want it to build up in the compost.)
I grew up in the south and rhubarb was not a plant of the south. I had never tasted it until I was grown and had a family. One year we flew all six of us to California to visit friends and relatives. A friend's wife served rhubarb crisp for dessert. One bite and I thought I had died and gone to heaven! They showed me the plant. I had never seen one before; it was small and had stems about the size of a pencil but longer.
Years later when our friend visited us something was said about me putting compost on my rhubarb. When he saw my rhubarb plants he said, "B...., you don't need to put compost on rhubarb that is that big!" My retort was, "It is that big, because I put compost on it."
We moved from that property to this one and I have had multiple compost piles here of different shapes and sizes and contents. Over the years mounds and mounds of compost have been used here in the garden.
Now, that I am older and not able to do all that physical work, I have scaled down hugely. My current favorite compost maker is one I ordered from a catalog years ago. In the catalog it was listed as the Green Cone Composter. I did an Internet search and noticed that it is now being called Solar Digester, but it looks just like mine.
I do not put animal material in it other than egg shells, and once or twice I poured in some soured milk. It is surprising how much it heats up inside. This one gets morning and midday sun. Even in the wintertime, when I lift the lid, I feel warm air puff out. In summertime, it is steamy. That is why I want the lid to stay on and in place, and why I was so vexed with the raccoons that kept opening it and letting it cool down and allowing rain to enter.
During the process of having our old roof replaced several years ago, roofers had to remove the old shingles, and falling shingles broke the lid. The leather flap was torn in two, and the lid had a big crack across it. I picked it up and put it back on, but rain could go through the crack and the heat could escape. I had a difficult time finding something that would fit over it. The diameter of the top was not the only problem; the cone shape itself posed a challenge because it gets larger as the lid fits down on it. I tried several pots and pans. Finally, I tried the pan section of an old cold-water humidifier. It fit, but eventually another family of raccoons discovered they could knock it off.
Now, I had to go back to trying a brick or stone on top of it. In time, it too developed a leaky crack and rain was getting inside. I didn't want my compost nutrients depleted by rainwater washing through and flushing them out.
Again, it had reached the point that I had to find another lid and throw away the old broken humidifier pan. The lid needed to be something waterproof, that would accommodate the expanding girth of the cone, and something that raccoons could not pull off.
I guess they could still dig into the ground and into the basket. Before, when they did that, I moved the dirt back into the hole and placed rocks where they dug before. As you can see in the photograph, my solution was a plastic bucket trug. I had them in three colors: red, blue, and purple. I rather like purple, so there it is; and purple and green are a pretty good combination... at least one I can live with.
(It looks blue in the photo, but it is really purple.)While that was going on, I utilized an old metal garbage can with a rusted out bottom. It collected all the new contributions from the house and a little from the garden. I hope to empty the Green Cone Composter (G.C.C.) soon, then move the summer's collection from the garbage can into it.
I am considering adding composting red worms to the G.C.C. I am thinking, if it becomes too warm or too cool inside, they can burrow into the ground. If any of you who have experience with vermicomposting have any thoughts on that, I would appreciate your input.
