Cardboard usage for weed suppression in gardening

Overview

Gardening techniques have been identified that utilize plain, unprinted cardboard to suppress weeds in garden beds. By covering weeds with thick, grey cardboard that is free of plastic tape, labels, or staples, sunlight is blocked, which causes the rhizomes of plants such as dandelions and couch grass to die off due to a lack of photosynthesis.

This method mimics natural forest processes. When the cardboard is covered with mulch or compost, it attracts earthworms that help aerate the soil and produce humus. This approach is noted for avoiding traditional digging, which can otherwise disrupt soil microorganisms and bring dormant weed seeds to the surface.
