🌡️ How to Start Composting: Step-by-Step

---

1️⃣ Place Your Compost Bin in the Right Spot

Choose:

✔ a sunny or partially shaded spot
✔ well-draining ground
✔ easy access for adding materials

---

2️⃣ Start With a Layer of Browns

Add cardboard or twigs at the base for airflow.

---

3️⃣ Add a Mix of Greens & Browns

Aim for:

👉 50% greens
👉 50% browns

This keeps the compost balanced and odour-free.

---

4️⃣ Keep It Moist — Like a Wring-Out Sponge

Too dry = slow breakdown
Too wet = slimy, smelly compost

Add water or browns as needed.

---

5️⃣ Turn the Compost Every Few Weeks

This introduces oxygen and speeds up decomposition.

---

6️⃣ Wait for the Compost to Mature

Compost is ready when:

✔ dark
✔ crumbly
✔ earthy-smelling
✔ all materials are broken down

Usually 3–12 months depending on bin type.

---

⚡ How to Speed Up Composting

✔ Shred materials first

Smaller pieces break down faster.

✔ Keep the bin warm

Plastic bins and tumblers work fastest.

✔ Turn regularly

Aeration = faster microbes.

✔ Add accelerators (optional)

Comfrey leaves, nettles, or manure boost nitrogen.

✔ Maintain moisture

Dry heaps stall — keep it damp.
