Place the fern's basket on a large upside-down pan or bowl. This holds the fern above the counter, avoiding damage to the "rabbit feet" rhizomes.
Spread the green fronds gently to locate the bottom of the dead fronds. Snip those off with scissors, just above the rhizomes.
Examine the fronds for evidence of pests or mildew. Powdery mildew is caused by excessive moisture or humidity. Pests include fungus gnats, mealybugs, red spider mites and whiteflies.
Divide rabbit's foot ferns by pruning all the fronds back to the base of the plant. Carefully remove the fern from the basket. Cut into quarters with a serrated knife and re-pot in small baskets using a potting mix for ferns. Do not cover the rhizomes with soil, rabbit's foot fern rhizomes grow on top of the soil. Water sparingly until new fronds appear.
