1. Your red anthurium needs regular watering
Being a plant that loves humidity, it needs its watering to be regular , but without becoming excessive, because you can rot its roots. It is best to check the top layer of soil to see whether it is already dry or not.
Humidity is key to making anthuriums thrive, however, you can’t take the easy routes like placing it near a humidifier or in a tray of pebbles. It is advisable to mist the leaves from time to time to give moisture to their leaves.
2. Use liquid fertilizer
For this type of plant, the ideal is to use a liquid fertilizer that is balanced with medium strength every two weeks during its growing season, i.e. from spring to autumn, in order to keep it healthy and stimulate flower growth.
