Without adequate humidity, the fronds turn brown and dry. Once this happens, clip out the damaged fronds - they won't recover - and keep the air around the fern as moist as possible. You may also see brown, dry fronds when ferns don't get the right amount of light or when you don't water or fertilize properly.

Pteridophytes (ferns and lycophytes) are free-sporing vascular plants that have a life cycle with alternating, free-living gametophyte and sporophyte phases that are independent at maturity. The body of the sporophyte is well differentiated into roots, stem and leaves. The root system is always adventitious.
