The top 1 to 2 inches of the soil should be allowed to dry out before watering again. A sign of over watering is yellow leaf tips and under-watering is brown tips. It's best to keep the soil slightly moist especially in the summer months.
Using a balanced fertilizer and ideally one with higher nitrogen will work well for Anthurium plants. Monthly feeding will work well when the plants are actively growing.
Anthuriums should never be exposed to direct sunlight. Plenty indirect sunlight is the best to for flowers to blossom. Keep your plant in a warm, well-lit spot.
18 to 26 degrees is ideal for Anthuriums. It's best to avoid the plant to be exposed to direct AC vents as the plant does not handle cool temperatures well.
A good rule of thumb for Anthuriums is when the plant reached 20 inches in a five-inch diameter pot, it is time to move the plant to a bigger pot. You can repot using this measure or every two to three years.
