Water well from spring to autumn and more carefully in the winter. They tolerate standing in water but not drying out. Keep plants away from direct sunlight as to much light will cause yellowing of the foliage. They are tropical plants and prefer warm temperatures, 18° is ideal but they will tolerate down to 15°. Keep drier in winter and apply liquid fertiliser regularly during the growing season. Occasionally wipe the leaves to keep them dust free. They prefer high humidity, old flower stems can be cut off and plants should be re-potted in the spring. They can be susceptible to spider mites and grey mould.
