What’s the problem?
My philodendron has long, white, string-like growths coming out of the stems. Is my plant OK and can I cut them off?
Diagnosis
These curious structures are known as aerial roots, and are completely natural. Philodendrons originate from tropical rainforests, where they climb trees. These aerial roots help it anchor itself, absorb moisture and draw nutrients directly from the humid air. Indoors, however, they can give the plant a slightly wild appearance.
Prescription
There’s no need for any concern or immediate action. Aerial roots are a sign of a healthy plant. If you find them visually unappealing, gently guide the roots on to a support, such as a moss pole or bamboo stake, to encourage your plant to climb. This helps it develop larger leaves and gives it an attractive shape. If you prefer to trim, use clean, sharp scissors to avoid damage or introducing infections.
Prevention
There’s no need to prevent aerial root growth, but providing your plant with adequate support will keep it looking neat and encourage lush foliage.
