Why does your Nephrolepis obliterata have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlySpider mites thrive in the low humidity environments common for Boston Ferns, creating fine silk webbing to protect themselves and their eggs. These microscopic arachnids pierce the fronds to suck out chlorophyll, leading to stippling or yellowing of the leaflets.
A specific subspecies that is highly aggressive in indoor settings with dry air. The webbing becomes denser as the population grows, often concentrated on the undersides of the Boston Fern's pinnae.
While not biological webbing, heavy dust buildup on Nephrolepis fronds can sometimes be mistaken for fine webs in low light. This layer prevents gas exchange and contributes to the drying out of the delicate fern leaflets.
