What is a Humidifier and Why Do Houseplants Need One?

A humidifier is a device that adds moisture to the air, helping to maintain a healthy humidity level. Houseplants need a humid environment to thrive, with most preferring a relative humidity (RH) between 40-60%. In nature, plants are surrounded by a humid environment, which helps to facilitate growth and development. However, the dry air in our homes can cause stress and stunt growth, leading to problems such as yellowing leaves, droopy stems, and reduced flowering. By using a humidifier, you can create a more hospitable environment for your houseplants, promoting healthy growth and development.
