COMPOSTING THE EASY WAY
Having an ample supply of good rich compost is
the gardeners dream. It has many uses, and all of those uses will result
in nicer plants. However, composting can be time consuming and hard work.
I place a reasonable value on my time, so spending hours and hours turning
compost piles doesn’t qualify as a worthwhile exercise, at least in my
book. Nonetheless, I do compost, but I do so on my terms.
I built two composting bins. Each bin is five
feet wide, five feet deep, and four feet high. I built the bins by sinking
4" by 4" posts in the ground for the corners, and then nailed 2 by 4’s and
1 by 4’s, alternating on the sides.
I left 2" gaps between the boards for air
circulation. The 2 by 4’s are rigid enough to keep the sides from bowing
out, and in between each 2 by 4 I used 1 by 4’s to save a little money.
The bins are only 3 sided, I left the front of the bins open so they can
be filled and emptied easily.
I started by filling just one of the bins. I
put grass clippings, dried leaves, and shrub clippings in the bins. I try
not to put more than 6" of each material on a layer. You don’t want 24" of
grass clippings in the bin and you should alternate layers of green and
brown material. If necessary, keep a few bags of dry leaves around so you
can alternate layers of brown waste and green waste.
When we root cuttings we use coarse sand in
the flats, so when it’s time to pull the rooted cuttings out of the flats,
the old sand goes on the compost pile. In our little backyard nursery we
also have some plants in containers that do not survive. Rather than
pulling the dead plant and the weeds out of the container, and then
dumping the potting soil back on the soil pile, we just dump the whole
container in the compost bin. This adds more brown material to the mix,
and is a lot easier than separating the soil and the weeds.
Once the bin is full, the rules of composting
say that you should turn the material in the bin every few weeks. There is
no way that I have time to do that, so this is what I do. I pack as much
material in the bin as I can before I start filling the second bin. I pile
the material as high as I possibly can, and even let it spill out in front
of the bin. Then I cover all the fresh material with mulch or potting
soil, whatever brown material I can find.
Then when I’m out working in the garden I set
a small sprinkler on top of the pile and turn it on very low, so a small
spray of water runs on the material. Since I have a good water well, this
doesn’t cost me anything, so I let it run for at least two hours as often
as I can. This keeps the material damp, and the moisture will cause the
pile to heat up, which is what makes the composting action take place.
Once I have the first bin completely full, I
start using the second bin. As the material in the first bin starts to
break down, it will settle and the bin is no longer heaped up, so I just
keep shoveling the material that I piled in front of the bin, up on top of
the pile, until all the material is either in the bin, or piled on top of
the heap. Then I just leave it alone, except to water it once in a while.
The watering isn’t necessary, it just speeds the process.
Because I don’t turn the pile, I can’t expect
all of the material to rot completely. The material in the center is going
to break down more than the material on the edges, but most of it does
break down quite well. The next step works great for me because I’ve got a
small nursery, so I keep a pile of potting soil on hand at all times. But
you can really do the same thing by just buying two or three yards of
shredded mulch to get started, and piling it up near your compost bins. If
you do this, you will always have a supply of good compost to work with.
Shredded bark, left in a pile will eventually
break down and become great compost. The potting soil that I use is about
80% rotted bark. I make potting soil by purchasing fine textured and dark
hardwood bark mulch, and I just put it in a pile and let it rot. The
secret is to keep the pile low and flat, so that it does not shed the rain
water away. You want the mulch to stay as wet as possible, this will cause
it to break down fairly quickly.
So I keep a pile of rotted bark mulch near my
compost bins. When both bins are completely full, I empty the bin
containing the oldest material by piling it on top of my rotted bark
mulch. I make sure the pile of rotted mulch is wide and
flat on top so that when I put the material from the compost bin on top of
the pile, the compost material is only 5 to 10 inches thick.
My mulch pile might be 12’ wide, but it may
only be 24 to 30 inches high. Once I have all the compost on top of the
pile, then I go around the edge of the pile with a shovel, and take some
of the material from the edges of the pile and toss it up on top of the
pile, covering the compost with at least 6" of rotted bark. This will
cause the compost material to decompose the rest of the way.
Once you get this system started, you never
want to use all of the material in the pile. Always keep at least 2 to 3
cubic yards on hand so you’ve got something to mix with your compost. If
you use a lot of compost material like I do, then you should buy more
material and add to your pile in the late summer or fall, once you are
done using it for the season.
Around here many of the supply companies sell
a compost material that is already broken down quite well. This is what I
buy to add to my stockpile. But I try to make sure that I have at least 3
yards of old material on hand, then I’ll add another 3 yards of fresh
material to that. Then in the spring I’ll empty one of the compost bins
and add the compost to the top of the pile.
The pile of usable compost will be layers of
material, some more composted than others. Kind of like a sandwich. So
what I do is chip off a section of the pile from the edge, spread it out
on the ground so it’s only about 8" deep, then run over it with my small
rototiller. This mixes it together perfectly, and I shovel it onto the
potting bench.
Having a pile of rotted compost near your
compost bins is great because if you have a lot of leaves or grass
clippings, you can throw some rotted compost in the bin in order to
maintain that layered effect that is necessary in order for the composting
process to work well.
Sure this process is a little work, but it
sure is nice to have a place to get rid of organic waste anytime I like.
Then down the road when I have beautiful compost to add to my potting
soil, I am grateful to have done the right thing earlier, and I know that
I have wasted nothing.
