gapbed

Gapbed is a horticultural term describing a raised-bed gardening system in which bed surfaces are interspersed with narrow gaps that serve as walkways, irrigation channels, or planting aisles. The phrase appears in some garden design discussions and extension materials, but it is not a standardized term with a single universal definition; practitioners may describe slightly different configurations under the same label.

In a typical gapbed layout, raised beds are built to improve drainage and soil aeration, with gaps between beds sized to allow access and to act as moisture-conserving, weed-suppressing pathways. The gaps may be left bare, mulched, or filled with ground-cover materials. Irrigation lines or drip tubing can run along the beds, delivering water directly to plant root zones while the gaps remain porous for air movement.

Advantages of gapbeds include better drainage, reduced soil compaction, easier harvest and maintenance, and more precise irrigation. Limitations include loss of planting area, greater material and labor inputs, and the need for ongoing gap management to prevent weed ingress or erosion on exposed pathways.

Variations of gapbed appear in home-gardening resources and some small-farm publications, often emphasizing intensive production and accessibility. The term should be used with the understanding that different sources may describe slightly different layouts under the same name.
