How to take care of anthuriums?
Anthurium comes in many shapes and forms. They are easy care and don't need so much.
Humidity:
Anthuriums need higher levels, you can lightly mist it's leaves daily but avoid water drops on the flowers. You can mist also aerial roots when they are there.
An tray with stones and water "pebble stone tray" is also very good source for humidity, even better than misting. You can place that tray under the plant pot or very near to the plant. Water evaporates slowly and creates better and more natural humidity for the plant.
Temperatures:
Normal room temperature is ok. They do not want to sit near heating elements at winter. Also be very careful when you ventilate your indoor air during winter. Anthuriums does not like cold or draft.
Watering:
Even tough it needs higher humidity you should let soil dry out little bit between waterings. In the summer time that can be 1-2 per week and at winter only 2-4 per month, depending how sunny, warm and dry your apartment is. Always test soil little bit deeper with finger before watering. Too wet/soggy soil will rotten the roots. Do not use ice cubes or cold water.
Feeding/fertilizing:
Anthuriums doesn't need much. Use 1/4 strength liquid fertilizer once every three to four months. You can use fertilizer which has higher phosphorus number for better blooming. Check here more about fertilizers.
Additionally, Anthurium flourish when treated with magnesium, which can be applied by adding a half tea spoon of Epsom salts to water when watering. Treat Anthurium with magnesium about once a month.
Light:
Anthuriums need only medium to bright indirect light, too much sun will burn and dry the leaves and flowers. If anthurium gets enough light, it can bloom almost all year around.
Repotting:
They do better when planted in pure sphagnum moss or a mixture which has three parts peat, one part gravel and one part chopped sphagnum moss. The coarseness of the gravel and the sphagnum moss can be altered depending on the age of the plant: Younger plant needs more water retention than the course mixture provides, but when it gets older it needs better draining soil.
Do not replant until the container is filled with roots or you have problems with plant roots.
Anthuriums are one of best air-purifying plants but keep in mind that as beautiful they are, they are also poisonous when eaten. Toxic for cats and dogs as it contains insoluble calcium oxalate crystals
