Size does matter. The smaller the particles that go in your tumbler, the hotter and faster your process (see Composting Physics).
I’ve loaded a tumbler with tall pulled weeds and waited almost a season
for finished compost. Worse, the compost didn’t heat up enough to kill
the weed seeds. Feeding your compostable material through a shredder or —
more economically — running over it a few times with a lawn mower helps
speed up the decomposition process.
Turn! Turn! Turn!
At
some point, it’s time to stop loading material into your tumbler. This
isn’t as easy as it sounds as the amount of material in the barrel
decreases in volume as the process proceeds. There’s always room for one
more pail of kitchen scrapes or another bag of grass clippings. But
adding more material sets the process back and you might find unfinished
carrot peeling or chopped celery garnishing your compost when it’s
otherwise complete. This makes for good reason to have a second tumbler
or a nearby heap to hold materials while a load is being finished (yes,
dear, I promise not to take my own advice). The stand-by pile goes into
the tumbler as soon as it is emptied.
How you turn your compost also has an affect. Don’t just rotate it
once and consider the job done. Swing it back-and-forth a number of
times after each spin to shake up the materials then spin it again. The
axle on which the barrel rotates goes through the center of your tumbler
and help breaks up the compostable material as it’s turned. Paddles and
piping in some tumblers have the same effect. Compost tends to become
compacted as it forms. Several good turns will assure that your compost
has been well broken up and mixed with air. This should be done a
minimum of twice a week and three or four times a week isn’t too much.
Spinning daily or more than once a day (your kids will be tempted since
spinning a compost tumbler can be loads of fun) doesn’t give the compost
a chance to attain maximum temperatures. While it doesn’t take long for
heat to build inside a properly filled tumbler, too much tumbling
dissipates heat and defeats the purpose.
It’s easy to understand why your tumbler should be positioned in
direct sunlight. Sunshine will help heat up what’s in your tumbler. The
darker the tumbler, the more it will heat up. We’ve found that a
digital, remote meat thermometer (sorry, dear, I promise to replace it
in time for Thanksgiving) is a great tool for assessing temperatures
inside your tumbler. Any reading short of 130-140˚F means you’re
probably not killing weed seeds or getting optimal decomposition (at
their most efficient, compost tumblers and bins can generate
temperatures as high as 200 degrees). Naturally, you’ll want to position
your tumbler strategically so that the finished product is unloaded
close to where it will be used.
Tipping Point
Following these procedures carefully will yield the promised results of finished compost
in a month or so. How will you know when your compost is ready? My
guess is that you know good compost when you see it. The original
leaves, grass clippings and kitchen scrapes have given up their
identities to become dark, rich humus with good clumping ability (no too
much moisture), texture and particle size. The volume of the material
inside the barrel will have been reduced to half (or less!) of its
original bulk. No finished compost is perfect and most gardeners will
screen their finished product to remove the inevitable small twigs,
woody carrot ends or other non-composted material.
Ignoring even one facet of good composting practice may mean it takes
eight weeks or longer for your compost to be perfect. It’s said that a
well-managed pile will produce compost just as quickly as a tumbler.
Such results are obtained by turning the piles as frequently as the
tumblers (every couple days) and constantly applying moisture to the
piles, something tumblers don’t require. To get the same results from
traditional compost piles as from a tumbler requires significantly more
work. And isn’t that why we use tumblers, to save time and energy?
One other benefit we’ve found our compost tumbler provides: it’s a
great conversation starter. The gardeners among our neighbors come over
and want to know how well it works. The most ambitious gardener on our
block has a commercial, multi-tiered home composting bin and he’s
constantly comparing the results (my tumbler — the EZ Tumbler —
works more quickly, I suspect because I show it more attention; and
delivers a larger volume of compost on completion, though he claims a
constant, but small supply is always waiting at the bottom of his bin).
I’ve even made some friends by giving away a pail of compost here and
there. What have they given me in return? Zucchini! As if I couldn’t
grow enough of my own…

I purchased a compost tumbler years ago and found that
the instructions for getting “2 week” compost involved using sawdust and
organic material. This was not practical for me so I began to “harvest”
the fall leaves, grinding them to fine particles with my leaf
blower/vacuum. I do not use grass clippings as I do not collect them. I
collect my kitchen waste in a large bowl, when it is about half full I
add water and use my stick blender to emulsify, then add that to the
tumbler. Works very quickly in the summer.

My husband and I just made a compost tumbler this weekend. It was a fun experience that I can’t wait to share with you guys.
We live in a kind of country area, the yard is big and it takes 15
minutes drive to a grocery store. Well, I know, for most Americans, 15
minutes on the road is nothing. American live in the car, their kids
grow up in the cargo. But for me, 15 minutes driving is really a hard
thing. I wouldn’t get into the car unless I couldn’t find anything
edible in my refrigerator. So we started a vegetable garden on the back
yard,that I wish I don’t have to go grocery shopping that often still
able to have whole food instead of processed food. Plus our diet riches
in fruit and vegetable, which contributes to a great amount of kitchen
scraps. In summer time, the waste gets stinky and gross in the trash
can, and it attracts bugs, releases nasty juice.
So, one day, after rinsing off the gross trash can, I decided to
cancel the trash service to start compost on my back yard. We compost
all the organic material, then bring the rest of trash to recycle
center. After that, no more fruit flies in my kitchen, and my garage is a
breeze. It might sounds like a lot of work to do, but if you try it,
you would find out it is such a easy, simple solution.
At the beginning, I looked around a kitchen compost collector, then
it turned out a little trash can would cost 20-30 dollars, some of them
requires biodegradable bag, which also sells at a ridiculous price;some
of them has a complicate filter, would broken over time… Then I saw this
little this little compost collector on amazon.com:
Full Circle Scrap Happy Scrap Collector and Freezer Compost Bin
It’s a simple plastic bin you can put in the freezer, so it doesn’t
have chance to attract fruit flies. I almost committed my money to this
compost bin, all of sudden, I realized: “why do I pay $13 for a tiny
plastic container? It’s a brilliant idea to freeze the perishable waste,
but I could use whatever container I have to put in the freezer.” So I
rummaged through my garage, found out a small bucket, used it as my
compost collector. It has been a month since I use this bucket as my
compost collector, so far, it worked perfectly. Everytime before you
dump the waste in to your outdoor compost, just fill some water in it to
help the ice melt from the inner side of the bucket, then rinse it off.
Composting in a pile works slowly. Because none of us want to turn
the pile, so we just see the pile shrinking, then add more stuff in it.
So far, our vegetable garden hasn’t been fed any compost. That’s
something I should be ashamed of. We’ve been planning about making a
compost tumbler for month, then we finally put this plan in action this
weekend.
We bought the treated wood, 10* 2-1/2 out door screws,wheels, hinges
and latches from Lowe’s, which cost about 20-30 dollars in total. The
water barrel was brought from craiglist at $25. The guy who sold it to
us said it was used for concentrated apple juice. So it’s good for using
as compost container, I don’t want any chemistry product in my garden.
The reason we mounted two lumber in the barrel is those would help
the compost mix better. I got the inspiration from front load washer.
Without them, the tumbler would be difficult to flip the compost.We saw a
lady used metal fins on her compost tumbler on Youtube. But we were
worry about if the metal fins could rust, so we chose treated lumber
instead.
We’ve considered about install a handle on the door, but the handle
would be too tall, then stuck in between of tumbler and the wooden
stand.
We are still thinking about why the door couldn’t be difficult to
close. It might be the plastic bending after been cut, or we mount the
door to close to the barrel on the hinges side,may be leave a small gap
would be better. We will make some adjustment on the next tumbler. I
will keep this updated.
I read this book about how to composting: How To Compost: Everything You Need To Know To Start Composting, And Nothing You Don’t!
This book only took me about two hours to read, instructed different
methods of composting, and what we should do, what we definitely need to
avoid. Cut and dry solution, very efficient. It was free when I ordered
the kindle version. It seems like Amazon.com rised the price of it.
