Harnessing orchids for traditional medicine: Cultivation and biodiversity conservation in Nirmala College campus, Coimbatore, Tamilnadu

Abstract

This investigation looks at how well orchids grow on a range of substrates, including sawdust, charcoal, coconut shell, and coconut coir, in order to identify the ideal media for orchid growth. Orchids are epiphytic plants requiring well-aerated and moisture – retentive substrates for successful growth. The study involved cultivating orchids on these four substrates under controlled condition, assessing parameters such as plant height, leaf number, root development and flowering rate. Results indicated that charcoal provided excellent aeration and root support, promoting robust root growth and healthier plants. Coconut coir retained moisture effectively but risked overwatering, while sawdust and coconut shell showed moderate growth outcomes. The finding suggests that a combination of these substrates could optimize orchid growth by balancing moisture retention and aeration. This research supports sustainable orchid cultivation by utilizing locally available organic materials, providing insights for both commercial growers and conservationists aiming to enhance orchid propagation.
