How to prune boston fern

Dead fronds: year-round. Hard rejuvenation: early spring. Remove dead fronds individually by cutting or pulling them cleanly at the base. For full rejuvenation, cut all fronds back to 5–8 cm above the soil in early spring, keep the plant warm and humid, and new growth will emerge within weeks.

Dead fronds as needed; rejuvenation every 1–2 years. Boston ferns develop tatty, brown fronds over time that drag down the plant's appearance. Remove individual dead or brown fronds at the base throughout the year. In early spring, you can cut the whole plant back by one-half to rejuvenate it — new fronds emerge quickly in warm, humid conditions.
