Turn a Patch of Lawn Into a Wild Garden Under a Foot of Arborist Chips

The Problem

Converting lawn to planting beds the usual way means stripping sod, tilling, or smothering with cardboard — and a few inches of bagged mulch on top of any of it. Cardboard and fine, uniform chips both cut off oxygen to the soil underneath, and a thin layer doesn't reliably kill the grass anyway.

The Technique

1. Source chips from an arborist or tree service, not in bags from a garden center. Arborist chips are a mix of species and sizes with the twigs left in — the coarse, irregular pile lets oxygen through to the soil and doesn't mat down.
2. Spread them 12 inches deep straight onto the lawn or meadow. No sod removal, no tilling, no cardboard underneath. The buried grass becomes food for the bacteria, fungi, and earthworms that move in.
3. Let the decomposers do the ground prep. As they break down the chips and the buried growth, they churn the soil below — the creator describes them as rototilling it for him.
4. Plant plugs or divisions from existing beds directly into the chip layer. Many perennials split easily, so one established mother bed stocks a lot of new ground.

Watch the reel to see the pile, the depth, and the planting — the scale is the convincing part.
