It is recommended to remove brown foliage from the fern. David Cohen, the CEO of plant wholesaler Badais International, advises that regular inspection of foliage and the removal of brown fronds can help to maintain the health and appearance of ferns. He recommends ‘trim the affected leaves at the base using clean, sharp scissors or pruning shears’ and adds that removing brown leaves ‘promotes new growth and prevents the spread of any potential diseases’.
