Impact of various trees barks potting mixture on performance of Cymbidium species

To understand the impact of various tree barks (pine bark, oak bark and Rhododendron) as a component of potting mixture on flowering size plants of five species of Cymbidium (C. longifolium, C. hookerianum, C. elegans, C. mastersii and C. gigantium), a five year trial was conducted. Results showed significant improvement in number of shoots/pot, height of plants at the time of flowering, plant fresh weight and dry weight, leaf number & length at six month and at flower emergence in all cymbidium species on pine bark potting mixture. Plant grown in pine bark containing potting mixture produced maximum number of spikes/plant and spikes/clump.
