Growth of Dieffenbachia maculata 'Camille' in growing media containing sphagnum peat or coconut coir dust.

摘要

A comparison was made of Canadian sphagnum peat (SP) and Philippine coconut coir dust (CD) as growing media components for Dieffenbachia maculata cv. Camille grown as a foliage pot plant.Three soilless foliage plant growing mixes (Cornell, Hybrid, Univ. of Florida 2 (UF-2)) were prepared using either SP or CD and pine bark (PB), vermiculite (V), and/or perlite (P) in the following ratios (percentage by volume): Cornell = 50 CD or SP:25 V:25 P, Hybrid = 40 CD or SP:30 V:30 PB, UF-2=50 CD or SP
