Besides feeding your plants and adding water holding capacity, composting is important for two more good sustainable reasons. Composting helps to minimize the trash going to our landfill, but most importantly doesn’t contribute methane to our atmosphere. When we compost, an aerobic condition is created and the bacteria that thrive create a waste product of CO2. Yes, carbon dioxide is a greenhouse gas, however methane is over 20 times more powerful in contributing to greenhouse gas effects.
Composting in summer’s heat is the fastest, just keep things moist! And there are several ways to do it!
In place composting
Long term is Hugelkultur. I say long term because you use logs and branches. Not only are you making compost, but heat! You can plant sooner in spring, grow later in fall. Building up, you get more surface area for planting if space is limited. If space is not an issue and you don’t want raised areas, dig trenches fill with logs, branches, twigs. Cover with the soil you dug up and other stuff. Same excellent results! There are many ways to Hugelkultur! Some projects are gentile and mini, others are huge!
- The classic is the three log triangle stack and hillock system. Put a bean trellis at the end of the pile!
- Lay a bed of thick diameter branches, small branches, and twigs at the bottom of your raised bed.
- Use logs to terrace your slope
Long term might be that pile in the back forty that you pay no attention to, other than dumping on more barrow loads from time to time and letting nature take its course. That can take years. But if your pile is warm in the sun and kept moist, at the bottom of that pile, eventually, not less than a year, you will get some fine leaf mold, and leaf mold is potent!
LASAGNA! Quick and dirty is composting right where you will grow things, and planting all along if you like! it’s the easiest on your back! If you have enough materials, all you do is chop and drop your disease free and seed free weed cuttings and lay your kitchen scraps right on the surface and let them decompose. Throw in some composting worms, red wrigglers. It will all go faster still, and you will have castings right where you need them! Throw some manures (no pet or human waste) about to ramp up the heat and Nitrogen plants need! Some people add other favorite amendments. Yes! Do keep things moist or thick/deep enough for the materials that contract the soil to decompose. To plant immediately, pull a space open, put already made compost in your planting holes and plant instantly! There’s no moving the compost you are making because it’s already where it is needed! There’s no turning, no space taken up by a composter. In summer it also acts as a mulch! Composting and mulch at once!
If you don’t have enough materials, do areas as you can, one at a time, each season another one. Consider giving your neighbors a container, or two, to collect their kitchen trim for you; ask for their landscape waste materials. Hooray, no trips to the dump!
Trenching kitchen scraps or burying garden trim 6″ to 8″ deep is really fast. Soil organisms get right to work! Again, keep that area slightly moist.
Composting in enclosures
Quick might be in a babied system in an enclosure, chopping things into small pieces, deleafing tough stalks, feeding with high class chopped, even blender chopped, kitchen trim! Trim could include squshed eggshells (keeps pH balanced), 0.5%, that’s 1/2 a %, or less of coffee grounds (suppresses fungal rots and wilts!). You could add some compost worms, red wigglers, so their castings are precombined with your compost! Careful layering, alternating WET/Nitrogen – grass, green trim, kitchen trim, and DRY/Carbon – leaves, straw, dried spent plants, makes for a well balanced process. Straw aerates, wets moisten and decompose the straw. 1″ wet to 2″ dry is good, but you get it, it’s 1 wet to 2 dry. Easy.
To Turn or Not to Turn! If you decide to turn, you need either a permanent two enclosure side by side system, or a lightweight movable enclosure. You may need to make your system secure from pests like rats or squirrels.
Turning speeds things up a tad, but research shows unturned compost is a little more nutritious. I use the enclosures you can lift off the pile. The pile doesn’t fall apart, so I move the enclosure to a nearby spot and pitchfork the pile into the new location. When things are well decomposed you will need to use a shovel. The pile goes back and forth every couple of weeks or so, leaving a spot that is enriched from the pile’s drippings, a prime planting spot! Then I move the enclosure to another spot.
Covering your pile with a heavy mil plastic, like old compost bags or trash compactor bags, keeps the pile moist. Water the fresh straw or leaves you add just a bit. Also, covering makes the worms feel safe from birds to come and feed at the top of the pile. When you take the cover off, the worms dive to get out of sight of birds!
6 months is usual, but since I add-as-I-have, part of the pile is ready sooner than the rest. I use the part that is ready; the rest I let keep processing. You can use almost finished compost sooner just fine! Mix it into the soil in the new planting area a couple weeks before planting and Baby, you quickly have tasty soil! The soil organisms ramp up and things are integrated down to the micro dots! However, if your compost pile isn’t going as quickly as you like, get some compost accelerator at your nursery or grow a compost activator plant like yarrow or nutritious comfrey next to your composter for convenient use! Add a few leaves to each layer as available.
Also use your compost for sidedressing. If it is summer, pull back your mulch. Push your spade fork in and carefully rock it back and forth to make some holes around your plant – not too close to the main stem, and as you feel to do. Lay down two to three inches of compost as you have available. Put your mulch back in place. Water slowly and gently to let the compost moisten, melt and drizzle into the holes, feeding the root area of your plants. It’s like giving them compost tea! Give it a few days to take effect. It’s especially effective when your plant starts into production, or as a late summer feed when they are pooping out. It will extend your harvest.
Some gardeners just divide their compost into big piles, make a water holding bowl in the top, and plant directly in the compost for super growth! Works great for a giant tomato plant, plants that are heavy feeders like Goliath-size winter squash, melons, Mammoth cabbage! How many times have you let a compost pile go and come back to find little plants growing in it?! They know what’s good for them! Cover the piles with some light blocking mulch, like thick straw, to keep the pile from washing away. Stick a stake beside your plant so you know right where to water.
- Hot is faster but more labor intensive, frequent turning a must to keep it going. Layering and balancing your ingredients is critical to get those temps. A thermometer is good to have, ideal temps 141°F to 155°F so weed seeds and disease pathogens die.
- Cold compost can be as simple as pile and wait. And wait. No concern about the order of things. Nature takes her course.
- My system is a hybrid system. I layer pretty carefully. My pile gets hot when I first layer in a new batch of stuff, but if I don’t turn it for a few weeks, that’s ok too.
Do what suits your needs or as you have materials, but compost, compost, compost! In these SoCal drought times, compost is the single most thing you can do for your soil to add water holding capacity! Keep your soil healthy and lively, with excellent friability, so it makes the most of what moisture it does receive.
Tyler W at Crazy About Compost, says: Just the other week, I had filled the bin up to the edge with new material…and I look out there today after forgetting about it and it’s dropped nearly a foot! This is what I love about compost piles – I’ve been adding material to this thing on a weekly basis and it’s just a bottomless pit of degradation.
The Green Bean Connection started as correspondence for the Santa Barbara CA USA Pilgrim Terrace Community Garden. We are very coastal, during late spring/summer in a fog belt/marine layer area most years, locally referred to as the May grays, June glooms and August fogusts. Keep that in mind compared to the microclimate niche where your veggie garden is. Bless you for being such a wonderful Earth Steward!
