Variegated ornamental plants, known for their diverse leaf colors and high market demand, present a unique challenge in preserving long-lasting aesthetic appeal. This study focuses on the development and optimization of zeoponic formulations as effective plant growth media (PGM) to promote sustained growth and visual excellence in two variegated ornamental plants, Epipremnum aureum "Marble Queen" and Peperomia obtusifolia "Green Gold." Zeoponics, composed of zeolite, compost, cocopeat, and fertilizers, is chosen for its high Cation Exchange Capacity (CEC) and aesthetic appeal due to its greenish-grey zeolite grains. Through greenhouse pot experiments and comprehensive PGM analysis, specific zeoponic formulations were identified for each plant species, yielding the most favorable results in terms of growth and appearance. For Epipremnum aureum "Marble Queen," PGM Z7, with Fe at 0.96 mg/l, Cu at 0.67 mg/l, Mn at 2.69 mg/l, and Zn at 1.67 mg/l, demonstrated the most favorable outcomes. For Peperomia obtusifolia "Green Gold," PGM Z6, containing Fe at 0.38 mg/l, Cu at 0.27 mg/l, Mn at 1.08 mg/l, and Zn at 0.67 mg/l, proved to be the most effective formulation. The study also revealed changes in the PGM's chemical properties, including pH reduction, increased electrical conductivity (EC), higher nitrate levels, and changes in micro-nutrient content. These findings offer valuable insights for enhancing the cultivation of variegated ornamental plants, benefiting the ornamental plant industry.
