Anthuriums are easy to grow. They have attractive foliage and will produce flowers all year round that last for a long time. Anthuriums are native to tropical climates and are grown commercially in such places as Hawaii and the Netherlands. Anthuriums will survive indoors, if properly cared for.
Keep anthuriums where it is very warm. They need to have a daytime temperature of 25.6 to 32.2 degrees Celsius, and a nighttime temperature between 70 and 75 degrees. If an anthurium is exposed to temperatures above 90 degrees, you will see faded flower colours, reduced life of the flowers and foliage burn. Anthuriums cannot live where there are frosts or freezes. If anthurium is kept outdoors during nighttime temperatures of 40 or 50 degrees, the plant grows more slowly and the leaves become yellow.
Plant your anthurium in a soil that is well-drained and coarse. The best type of soil would be one with a 1-to-1-to-1 ratio of peat moss, perlite and pine bark. Young anthuriums thrive in less coarse soil, but mature plants require the peat, perlite and pine mixture.
Water anthurium thoroughly and allow the plant to dry out slightly, but not all the way, between watering. If you allow your anthurium to dry out, the plant will not grow as tall and you might see burning on the tip or damage to the roots. Be careful not to overwater anthurium, as this can also cause damage to the roots.
Fertiliser is not required on anthurium but can provide the greatest number of nutrients. Do not fertilise anthurium until it is a mature plant. Then use a light solution, with a small ratio of fertiliser to water. Dilute the fertiliser to at least one-quarter strength before putting it on the plant.
Give anthurium as much light as possible during as much of the day as you can. However, the light should not be direct sunlight. Without sufficient light, the plant will not grow as tall and you will see a reduction in the number of flowers.
