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. They should be planted in raised beds of 1.3 to 2 metres wide and 20 cm deep. The plants should not be planted more than 5 cm deep, as deep planting results in rotting of stems and roots. Some plants may need to be staked after planting for support.
