No-Dig Gardening: The Complete Walkthrough
This guide covers no-dig gardening, rated an easy task, typically taking half a day/bed.
Our printable card on no-dig gardening covers the essentials at a glance — here's the fuller walkthrough.
Sheet layers smother and build
A no-dig bed is built directly on top of existing ground — cardboard smothers weeds and grass below, while layers of compost and mulch above create a fertile growing medium without digging or tilling at all.
What You'll Need
The key things to get right:
- Cardboard (uncoated, tape removed) or newspaper
- Compost, aged manure, or a soil mix
- Straw or another mulch for the top layer
- Optional: a timber or other edging to contain the bed
Step by Step
A few things matter most here:
- 1. Mow or slash existing growth low, then lay cardboard directly over the area, overlapping generously.
- 2. Wet the cardboard thoroughly to help it break down and stay in place.
- 3. Layer compost and aged manure on top, building up to at least 15–20cm depth.
- 4. Top with a mulch layer to retain moisture and suppress any weeds pushing through gaps.
- 5. Plant directly into the top layer — seedlings work better than direct-sown seed in the first season while the layers are still settling.
Common Issues
The key things to get right:
- Weeds coming through — gaps in the cardboard layer; overlap more generously next time, or patch gaps with extra cardboard.
- Bed sinking significantly — normal as layers settle and compost breaks down; top up each season.
- Poor growth in the first season — layers may not have broken down enough yet; established no-dig beds generally improve markedly by year two.
- Persistent perennial weeds (like couch grass) coming through — a single cardboard layer may not be enough for very vigorous weeds; consider extra suppression measures first.
Ongoing Timing
Best time — autumn is ideal, giving the layers time to break down before spring planting, though it can be built any time. Duration — initial build takes half a day; the bed improves and matures over the following seasons. Maintenance — top up compost and mulch each season as layers settle and break down. Signs of success — rich, dark, crumbly soil developing at the cardboard interface, and strong plant growth without ever having dug the bed.
