Best organic compost for enriching garden soil with natural nutrients and improving plant growth.

If you’re just stepping into the world of organic growing, here’s one truth you’ll hear again and again: healthy plants start with healthy soil.

And the simplest, most sustainable way to improve that soil? Organic compost.

Composting is the natural process of breaking down food scraps, yard waste, and other biodegradable materials into a nutrient-rich soil amendment. In short, it’s turning waste into food—for your soil.

And don’t worry—getting started is easier than you think.

Whether you’re working with a backyard setup or just a kitchen corner, today’s composting tools make the process clean, simple, and almost odor-free.

1. Why Compost? A Quick Look at the Benefits

If you’re growing anything—from backyard veggies to balcony buds—organic compost is one of the smartest, simplest tools in your grow kit.

Composting transforms food scraps, leaves, and other natural waste into nutrient-rich, microbe-packed material that your soil (and plants) will absolutely love.

So, why bother composting?

  • Less waste in landfills
  • More fertility in your garden beds
  • Better yields for cannabis, vegetables, and herbs
  • Cleaner inputs for organic growing standards

For beginner growers, learning how to compost is the gateway to a healthier, more self-sufficient garden.

Whether you’re curious about indoor composting, worm composting bins, or just wondering how to start a compost pile, this guide has your back.

Want a head start? Products like Dr. Earth Organic Compost are great if you’re not quite ready to wait months for your own pile to break down—just open the bag and get growing.

In the next section, we’ll get into the nitty-gritty of what goes into a great compost mix (and what to absolutely avoid).

2. What You Can (and Can’t) Compost

If you want your organic compost to work like nature’s fertilizer, it starts with choosing the right ingredients—and avoiding the ones that turn your pile into a pest party.

What to Put in Your Compost Pile

These ingredients feed the microbes, break down beautifully, and turn into nutrient-rich compost gold:

What Not to Compost

A few wrong items can ruin a perfectly good pile—and invite trouble:

  • Meat, dairy & oils – These rot fast, smell worse, and attract rodents
  • Pet waste, diapers, or anything from the litter box – Contains harmful pathogens
  • Glossy or coated paper – Not compostable and often full of inks or toxins
  • Plastic, foil, or synthetic trash – Composting isn’t magic (yet)

Even with the best kitchen compost bin, if you toss in the wrong scraps, you’ll be dealing with flies and stink instead of sweet, earthy humus.

3. How to Make Organic Compost (Composting 101)

Now that you know what goes in (and what definitely stays out), it’s time to break down how to make organic compost from scratch.

The composting process isn’t complicated—but it is a dance between heat, oxygen, moisture, and the tiny microbes doing all the heavy lifting.

Composting Methods: Pick Your Style

There are two main composting approaches—and which one you choose depends on your space, timeline, and how hands-on you want to be.

Aerobic (Hot Composting)
This is the go-to method for quicker results. It requires:

  • Regular turning to introduce air
  • Proper moisture (like a damp sponge)
  • A solid 3:1 carbon-to-nitrogen mix

You’ll get finished organic compost in as little as 6–12 weeks—and it’s the best way to suppress weed seeds and pathogens thanks to the heat.

Anaerobic (Cold Composting)
This is more of a “set it and forget it” style:

  • Less effort (just stack materials)
  • Takes longer (months to a year)
  • Can get smelly without airflow

Cold composting still works—but you’ll need patience.

The 3-Part Compost Cycle

Whether you’re working with a backyard compost bin, indoor composter, or open pile, composting follows a natural rhythm:

  1. Build it: Layer your greens and browns (aim for 3 parts brown to 1 part green). Start with coarse material like straw or cardboard at the bottom to help airflow.
  2. Maintain it: Keep it moist—like a wrung-out sponge. Turn it once a week to add oxygen and activate microbial breakdown.
  3. Harvest it: In hot systems, your compost is ready in 6–12 weeks. Look for a dark, crumbly texture, and that fresh, earthy smell. That’s black gold.

Want to speed things up? Mix in a nitrogen booster like Burpee Organic Blood Meal to heat up the pile and fuel microbial activity. It’s especially helpful for cool climates or lazy piles that need a jumpstart.

4. Composting at Home: Setup Tips for Success

You don’t need a farm—or even a backyard—to make high-quality organic compost.

Whether you’re in a small apartment or managing a backyard grow, there’s a composting setup that fits your space, lifestyle, and goals.

For Indoor Composting:

Urban grower? No problem. Indoor composting can be simple, clean, and surprisingly low-maintenance.

  • Use a countertop compost bin to collect daily scraps. Look for one with a charcoal filter to keep smells in check.
  • Try an electric or odor-controlled composter like the Lomi compost system (product link coming up!). It breaks down food waste in hours—perfect for small kitchens.
  • Best for apartment dwellers, indoor growers, or anyone who wants fast compost without stepping outside.

For Outdoor Composting:

If you’ve got a bit more space to work with, outdoor systems offer more flexibility and volume.

  • Go traditional with a compost bin, rotating tumbler, or even a DIY pallet setup.
  • Line your bin with biodegradable garbage bags for easier cleanup and fewer messes.
  • Set it up in a shaded spot with good airflow and drainage to avoid soggy or stinky compost.

Vermicomposting for Tight Spaces

Short on square footage or worried about odor?

Vermicomposting bins (worm composting systems) are an incredible way to break down kitchen scraps—fast and odor-free. Red wigglers do the heavy lifting, and all you have to do is feed them and keep their bedding moist.

Pro tip: Vermicomposting is perfect for year-round use, especially if you want to compost in winter or keep things running indoors when the garden’s frozen over.

5. Best Composting Products to Get Started

If you’re ready to turn food scraps into rich organic compost but don’t want to deal with the mess, smells, or trial-and-error of DIY piles, the right tools can make composting way easier—and much more effective.

6. Compost Quality & Troubleshooting

So you’ve been layering, turning, maybe even spinning your compost tumbler like a champ.

But how do you know when your organic compost is actually ready—and what to do if it’s not quite going to plan?

Here’s how to judge compost quality, troubleshoot common issues, and rescue a pile before it turns into a soggy mess (or a science experiment).

What Finished Compost Should Look, Feel & Smell Like

When your compost is fully broken down, you’ll know by checking three things:

  • 👀 Look: Deep brown to black, crumbly like chocolate cake
  • ✋ Feel: Slightly damp—not mushy or dripping wet
  • 👃 Smell: Earthy and fresh, like rich forest soil (not like last week’s leftovers)

If it still smells sour, feels slimy, or you can recognize last night’s potato peel, it needs more time—or more balance.

Common Compost Problems (And How to Fix Them)

ProblemCauseFix
Too Wet or SmellyToo many “greens” (nitrogen-rich scraps), poor airflowAdd “browns” like shredded paper, leaves, or cardboard. Turn pile to introduce air.
Too Dry & Not Breaking DownNot enough moisture or juicy greensMist with water and add scraps like melon rinds, coffee grounds, or wilted veggies.
Pile Not Heating UpOff-ratio of greens/browns, pile too smallAdd a nitrogen booster like Burpee Organic Blood Meal, and build a pile big enough to insulate heat (3x3x3 ft minimum).
Flies or PestsExposed food scraps, wrong ingredients (like meat/dairy)Bury new scraps under browns and avoid composting animal products.

👃 Pro Tip: If your compost smells worse than your gym socks, it’s sending a distress signal.

Most issues come down to poor aeration or too much wet waste.

A few shredded leaves and a good turn usually work wonders.

Want to speed up the fix? Keep a bag of Dr. Earth Organic Compost on hand to mix into stalled or smelly piles—it adds active microbes that bring things back to life.

When you’re ready to blend your finished compost into containers, the Back to the Roots Potting Mix helps lighten and balance the texture of the top dressing or transplanting.

7. Using Organic Compost for Gardening or Farming

Whether you’re growing backyard veggies, cannabis, or fruit trees, organic compost is the MVP of soil-building.

It doesn’t just “feed the plants”—it builds an entire ecosystem underground.

Here’s how to make compost work for you, naturally.

7.1 Organic Compost and Soil Fertility

Healthy soil isn’t just dirt—it’s alive. And compost is what feeds that life.

  • Organic compost matter boost: Compost increases soil structure, improves aeration and encourages strong root growth.
  • Water retention: Especially helpful in dry climates—compost holds moisture like a sponge.
  • Slow-release nutrients: Compost delivers N-P-K and trace minerals over time, helping avoid nutrient burn.

💡 Pro Tip: Mix your finished compost with Back to the Roots Organic Potting Mix for a high-performance grow medium—perfect for containers, raised beds, or transplants.

7.2 Organic Compost and Disease Suppression

Good compost = healthy soil microbiome. That means:

  • Fewer diseases like root rot and damping off
  • Natural protection from soil-borne pathogens
  • Support for beneficial fungi and bacteria in the rhizosphere (root zone)

A strong soil web creates resilience. So your plants are less stressed, and your yields look better come harvest time.

7.3  Application Rates & Timing

So, how much compost should you actually use?

WhereHow MuchWhen
Raised beds1–2 inches across the topPre-planting or mid-season boost
Lawns¼ inch top-dressSpring or fall (aerate first if possible)
Potted plantsMix 20–30% into potting soilAt transplant or refresh time
In-ground gardens1–2 inches worked into soilPre-season, side-dress mid-season

🌿 Use Dr. Earth Organic Compost if your pile isn’t quite ready yet—it’s a fast-track option for getting microbes and structure into your soil today.

8. Compost and Organic Certification (Quick Guide)

If you’re growing to sell—or just want to keep things truly clean—you’ll want to understand what qualifies as “organic” compost under the USDA’s National Organic Program (NOP).

Allowed:

  • Fully decomposed plant-based compost
  • OMRI-listed inputs (like Dr. Earth Organic Compost)
  • Worm castings and animal manure (if properly composted)

Not allowed:

  • Compost made from sewage sludge
  • Non-organic yard waste (e.g., sprayed lawns)
  • Any compost with synthetic additives

👉 Pro growers: Always check product labels for OMRI or NOP certification to stay compliant.

9. Composting FAQs

How long does it take to make compost?
Hot piles can finish in 6–12 weeks. Cold piles may take 6–12 months.

Can I compost in winter?
Yes! Cold slows it down, but insulated bins or vermicomposting keep it going year-round.

What’s the fastest way to compost?
Use a hot compost pile + turn weekly + add Burpee Organic Blood Meal for a nitrogen boost.

Is compost safe for seedlings?
Yes—just make sure it’s fully finished and sifted. Mix with Back to the Roots Potting Mix for ideal texture and drainage.
