How to make a lot of compost this winter

Compost is a gardener’s best friend. Unfortunately, it can be quite expensive if you have to purchase it. The cost in my area is about $30 per cubic yard. I can drive about an hour and a half and get mushroom compost for $10 a cubic yard. So, what’s a person to do who wants a lot of compost for the spring but doesn’t want to buy it? Make it. And make a lot of compost in the winter.

Now, I know what you’re thinking, “That’s easy for you, you have chickens and can use their bedding, I don’t”  or “We don’t have many food scraps so it’s not worth it.”

I’m going to share our super secret ingredients for making lots of compost first and then I’ll share some tips and other things you can add to it. Oh, and a printable compost list for you to put in your gardening notebook.

And the super secret ingredients are…leaves from your neighbor’s curbs and used coffee grounds

Composting leaves quickly

We start collecting leaves as soon as we notice people bagging them up and putting them on their curbs. You can tell they are leaves because they are usually in brown paper lawn bags. It’s okay to take them, but if it makes you feel better you can ask first.

In our area this doesn’t happen usually happen until early winter (mid to late December). So if you live in a zone 9 gardening zone know that it might seem like the leaves will never fall but eventually  they will.

Several times a week we go into our Starbucks or local coffee house and ask if they have any used coffee grounds. They almost always do. They’re happy we take them off their hands.

Why does this work?  Dried leaves are considered a “brown” in the composting world; that means they have a lot of carbon. The microbes in compost use carbon as their energy to thrive. Coffee grounds are considered a “green” (yeah, I know they’re not green); that means they have a lot of nitrogen. The microbes in compost use nitrogen as their protein to thrive.

Composting basics

Here’s the deal, any organic matter will compost down….eventually. If you don’t want to wait indefinitely you will need to build a compost pile that has browns and greens mixed throughout.

So, open a bag of leaves and put about 4 shovelfuls of leaves in the area you are going to use for your compost pile and then sprinkle a shovelful of coffee grounds on top and sprinkle with water. Keep layering until you run out of either leaves or coffee grounds, making sure you dampen each layer.

Every few days turn the compost pile and make sure it smells fine, looks fine and isn’t too dry. If you want to speed up the process even more run the leaves through a mulcher and then use a 1:1 ratio of leaves and coffee grounds.

Browns are things like dried leaves, shredded paper and cardboard,  wood chips, hay, mulch and wood ash (although I like to use this directly in the garden instead of composting it).

Greens are things like fruits, vegetables, coffee grounds and filters, tea bags, manure (cow, horse, goat, chicken, sheep and rabbit) and  grass clippings.

Don’t compost things like pet waste, fats and oils, meats and bones, coal and charcoal, dairy or anything with pesticides or diseased plants.

Your compost should have an earthy smell to it. If it smells bad, you need more nitrogen. If it’s slimy, you need more carbon. If it’s really dry, you need to dampen it. See, it’s really not complicated.

Where to put your compost pile? Most people who compost have “a” pile or bin that they use which is kind of hidden out of the way. We do, too. However, we’ve decided to start composting IN the gardening beds that are not being used for our fall/winter garden so they will be ready in the spring.

Once we cleaned out the summer plants, I planted buckwheat in the beds that we’ll be using in the fall, and I started compost piles in several others using chicken bedding and coffee grounds. When we gather more leaves we’ll start composting in other beds. It’s similar to the lasagna method of gardening.

I’m not anticipating that these piles will get super hot since they are only a few inches high. So, I’m covering most of them with tarps to keep the heat in. Come spring if there are any leaves or bedding that hasn’t composted down we’ll just rake it up and put it all in our permanent compost pile.

Composting in the winter

During the winter the composting microbes will slow down and if you live in a really cold climate, they’ll stop. But it’s okay to still compost in the winter. Continue adding adding your household scraps to the compost pile or bin even though they freeze. The freezing and thawing cycle will actually help the compost break down quicker in the spring.

When things really start to melt in the spring, add some leaves or straw to cover the composting pile. You don’t really need to add leaves or straw during the winter when you add household scraps if your compost freezes. The frozen compost won’t be odorous and attract animals. Of course, if you’re worried about that go ahead and add leaves to the compost.

Composting and your climate

Your climate affects every part of gardening, including how you compost. The basics are the same but the process will be different. If your winters are harsh and long you’ll compost differently than someone who lives in an area that almost never experiences a freeze.

Composting is both a science and an art. There are ratios that you can follow to help speed up the composting process and make proper compost – that’s the science part. But you can’t control the weather, you can only observe it and tweak what you’re doing in response to it.

The important thing is that start where you are and with whatever compostable items you have or can gather. 

I made a handy printable to help me remember what items are browns and what are greens. To download your copy just fill out the form below.

Once you print it up, you can put it in your gardening notebook. I find that the more notes I keep on my gardening efforts the more I enjoy gardening and the more productive my garden is. If you don’t already have a notebook for your notes, consider purchasing the printable gardening notebook I created to help gardeners have a more productive garden.

Are coffee grounds from Starbucks pesticide free?

Honestly, I have no idea. I've never had a problem with them messing up my compost...and I'm comfortable drinking Starbucks coffee...if you aren't you might want to pass on their coffee grounds.

Awesome tip. Thanks for the information.

When I have a bed not being used I save my kitchen cuttings and dig a hole which then they are placed in. The worms eat it in no time. I do the same next to that spot and work along the bed. The holes only need to be a shovel deep. This works great if you don't have space for a compost pile. It can work in pots too.

@Nancy, I just pile up grass cuttings and leaves, garden waste (weeds, clippings, sticks) in several out- of-the way places throughout the year. When I want mulch or stuff to enrich the soil or improve drainage, I raid one or more of these piles. I make sure that dirt gets into these piles from weed roots or a shovelful/handful of earth from time to time. Very low maintenance, yet the yield is fantastic, and easily creates healthy, vibrant plants! It's probably worth planting a few shrubs somewhat just to have a “hidden location” for this natural process that is screened from view. An elderly neighbor practiced this and taught me her gardening practices. She had incredibly rich soil and excellent drainage throughout her thriving garden.

Beginner gardener here. My husbands grandfather used a hole in the ground for his compost. Apparently he was a great gardener and hole digger. He is no longer around so i was wondering if this would be a good idea to keep the compost warmer during the winter. How does heat or cold affect the yeild of compost? Also should you turn your piles during the winter when there is snow on the ground?
