Time to Compost – Harvest the Biomass on the Ground

As far as I am concerned the leaves that fall in the fall tra-la are as welcome as the flowers that bloom in the spring. When I lived high on a windy hill in Heath all the leaves blew away. I helped a neighbor rake leaves, and took them away to my compost pile. I loved picking up a few bags of leaves that people left in front of their houses when I came into Greenfield to shop. I needed leaves for my compost pile. Now that I live in Greenfield I no longer have to go begging for autumn leaves.

If you have never set up a compost pile there are books like Let it Rot by Stu Campbell devoted to composting; many garden books give information about composting; and locally we have the Franklin County Waste Management District to give us directions about composting online at franklincountywastedistrict.org/composting.html.

After reading all the instructions my advice is not to worry about details too much and just begin. Compost is all about rotting organic material. Fast or slow the result is the same. So, just begin.

Don’t worry about ratios. Some directions seem to imagine us building a compost pile after we have been collecting enough green material like fresh grass clippings or spent annuals or other clippings, and sufficient brown materials like manure or dead leaves before we start our compost pile. Meat and bones are always forbidden. A compost pile should measure at least four feet high and wide. Sufficient size is necessary to build up heat in the rotting pile that will help break materials down and kill harmful pathogens and weed seeds. Explicit instructions like that have been known to stop me in my tracks.

Fall is a great time to start a compost pile because dried leaves, spent annuals and all the trimmings from cutback perennials make a good start for a compost pile. Alternate layers if you have green and brown materials, but don’t worry about it. Be sure to water the pile. A moist pile, not a drenched pile, will break down more quickly.

Compost directions always say to turn the pile periodically and that is certainly good advice, if not always easy to carry out. Some gardeners have the space and the forethought to build a three bin compost pile made out of cinder blocks or chicken wire or wooden slats. They begin the pile in space number one and when the space is full they turn the pile into space number two.  When number one is again full, fork number two into number three, and number one into number two. Then start filling number one. By the time number one is full again the composting materials in space number three should be ready to spread or dig into the soil. Continue in this manner forever.

I have seen an inexpensive compost aerator tool that you plunge into the pile. The tool has a long handle with little paddles at the bottom. When you pull the aerator out of the pile the paddles loosen and stir up the compost, letting in some air.

I have admired many compost piles, but mine have never been lovely or organized to look at. However they have made completed compost that helped me improve my Heath soil for over 30 years. Now I am beginning to improve my very poor, very heavy Greenfield soil.

I started with compost that I bought and we are lucky that we have Martin’s Farm right in Greenfield that composts on a major scale and sells compost, mulch, compo-mulch, and loam. Nearby is Bear Path Farm in Whately, also selling good compost. I needed to get my new garden off to a good start; compost and mulch were the way to do that.

Now that it is fall I am starting my own composting efforts in earnest. This summer I bought an Earth Machine compost bin at the Greenfield Transfer Station. I began by putting in weeds and kitchen scraps. Now I’m adding leaves that provide some real bulk. We also had some scrap fence wire and used it to build a special leaf compost container. It is about five feet tall and 4 feet in diameter. It is full of leaves, but they are already breaking down and we can keep adding leaves.

Many years ago when Larry Lightner of Northfield was still alive and gardening he taught me about what he called cold composting with leaves. He made wire rings about three to four feet high and as large in diameter as he wished. He filled and refilled these rings with leaves over the course of the fall. In the spring the pile would have  shrunk substantially. He added more leaves if he had them. Then he would make an indentation in the leaves, fill it with a quart or so of good soil and plant vegetable or flower starts. It is important to keep plants in a cold compost bed well watered.

Lightner’s cold compost beds were essentially raised beds. They provided plenty of nutrition for his chosen plants. He could even plant and stake tomatoes on the outside of the wire ring. Their roots found plenty of sustenance from the nutrients going into the soil as the leaves broke down. The raised beds also kept neighborhood dogs and cats out of his garden beds.

I have another friend who told me she has an electric leaf shredder. Shredding leaves will certainly help leaves break down more quickly. She wants to use those shredded leaves as winter mulch on her garden beds. In the spring she told me they have pretty much turned into soil. Not much is left of the leaves at all.

There are many ways to make and use compost. It is a never fail project. It is a rewarding project. It is a project that benefits the garden, and keeps material out of the landfill or incinerator. Compost!

Thank you all for bearing with me while we hammered out the technical difficulties that kept the commonweeder off line for a few days.

    We’ve never dared to have a compost heap because of drawing wild animals. We are surrounded by a lot of them! I’ve heard that mowing the leaves on the lawn is good for the lawn. They get all chopped up.

  2. Lisa at Greenbow

    I mow my leaves and blow them into the flower beds. By spring the leaves are broken down and I have a nice layer of compost already in the beds.

  3. Denise Hammond

    I also blow my leaves into beds and cut them up with the lawn mower. I just learned that they provide good cover for toads which must be why I have so many in my yard.

  4. Pat

    Nan – I’ve heard a lot about the wild animals in our new neighborhood, including an albino skunk, but so far no trouble with the compost bin which does have a lid. Those chopped leaves are a gold mine in the beds and the lawn.

  5. Pat

    Denise – I’ll look for toads in the fall. If they appreciate wet as well as leaves I’ll have no shortage.
    Lisa – Having my own leaves is such a boon. I can’t wait to see the beds in the spring.

    Cold composting – an interesting idea
    Happy Thanksgiving!

    I love your point to just do it! I get overwhelmed by all of the directions too, and it’s really pretty simple. I attended a great presentation by my daughter’s fifth grade class last week wherein they talked about compost systems that they would set up in the school cafeteria to provide compost to the school gardens. It filled my heart to see these young kids really “getting it”, along with several of their parents. Maybe there is hope for the world! We all just need to compost more!
