Mulching Done Right — Why Technique Matters As Much As Material

Mulching looks simple — put wood chips around plants, done. But done incorrectly, mulch can rot plant crowns, harbor pests, block water from reaching roots, and actually harm the plants it's supposed to protect.

The Volcano Problem

The most common mulching mistake is piling mulch against tree trunks and plant stems — the 'volcano' effect. This traps moisture against the bark, promotes fungal disease, and invites boring insects. Keep mulch 2-3 inches away from all trunks and stems.

Depth Matters

Two to three inches is the correct depth for most applications. Less than 2 inches doesn't suppress weeds effectively or retain adequate moisture. More than 4 inches blocks water and air from reaching roots.

Material Considerations

Shredded hardwood is the standard for most DC Metro landscapes. Pine straw is excellent around acid-loving plants like azaleas and hollies.

When to Refresh

Most DC Metro landscape beds need fresh mulch once per year — typically spring. A light refresh in fall helps insulate plant roots through winter.
