mulchplug

Mulchplug is a term used in gardening and landscaping to describe a small plug or disk designed to be placed in mulch beds to manage mulch distribution and moisture around plants. The plug is typically made from plastic, rubber, or biodegradable materials and is sized to fit common mulch depths around trees, shrubs, and garden beds.

Typical applications include maintaining a consistent mulch depth to suppress weeds, reducing material loss due to wind and irrigation, and protecting plant crowns from excessive moisture or soil splash. Some mulchplugs are vented to permit airflow and water infiltration, while others are solid to provide greater durability and weed suppression. They can come in colors or textures to blend with the mulch or landscape.

Installation and use: Position the mulchplug at regular intervals around a planting area or at the edge of a mulch ring, pressing it into the mulch so the top sits flush with the surface. In raised beds, plugs can be placed around bed components to hold mulch in place while still allowing drainage. Biodegradable variants can be left to break down over seasons.

Durability and care: UV-stabilized plastics extend life; replace when degraded. Price ranges vary by material and size.

Alternatives and related concepts: edging, weed fabric, mulch mats, or traditional mulch rings.
