This study developed meshball-mediated air-pruning, a method embedding stainless-steel spheres into soil to create localized aeration pockets, addressing issues like root circling, poor aeration, and inefficient resource use in containerized plant cultivation. Testing across four species revealed significant benefits for ornamental shrubs such as dwarf ixora and firebush, showing increases in shoot fresh weight, branch number, and root biomass. However, pak choi exhibited no measurable change, and white teak seedlings displayed reduced root biomass, indicating species-specific responses.
