Replanting After Stump Grinding: Soil Prep and Nitrogen Management

Three large trees removed and stumps ground two years ago. Area keeps sinking—mostly mulch/chips 1 foot deep. Owner asks what to plant.

Why It Sinks

Grinding leaves chips 18-24 inches deep. As they decompose, volume decreases, causing settling.

Replanting Steps

1. Fill sunken areas with quality topsoil.
2. Plant new tree slightly off-center from old stump to avoid remnant wood.
3. Critical: Apply nitrogen fertilizer—decaying chips consume soil nitrogen, starving new plants.

Any species can be planted once soil is amended. Monitor for nitrogen deficiency (yellowing leaves) and fertilize accordingly.
