Tissue Culture Plants can also be propagated by tissue culture. The University of the West Indies, St Augustine, propagates anthuriums by this method. The Plant Quarantine Department of the Ministry of Food Production allows only tissue cultured propagated anthurium plants to be imported into Trinidad and Tobago. This is in order to keep out diseased planting material from entering the country. When planting, it is best to not mix varieties, as taller types will smother shorter types.
Anthuriums grow on a wide range of soil types ranging from sandy loams to heavy clays.
However they grow best in a highly organic soil with good water retention capability and good drainage. A well-drained soil is important to prevent rotting of stems and roots. Anthuriums require shade for proper growth and for good quality flowers. Too much sunlight causes bleaching of the flowers and yellowing, while too much shade slows down growth and flowering. Synthetic shade cloth supported by galvanized pipes and wire is recommended providing uniform shade, reduces insect damage and keeps plants clean from pests and debris.
