cinnamon fern

Cinnamon ferns (Osmundastrum cinnamomeum) should be watered every 2 to 3 days. To water the ferns, give the soil a thorough soaking, such that water runs out of the bottom of the container, and then wait until the top 1-2 inches of soil is dry before watering again. These ferns should not be left in overly wet soil, as this can lead to root rot and other fungal issues. If possible, it is best to water the cinnamon ferns in the morning to allow the foliage time to dry off before nightfall. During especially hot weather, providing extra moisture (a light misting) during the afternoon hours can help keep the foliage cool and prevent scorching.

Cinnamon ferns thrive in partial to full shade, meaning they do not require a lot of direct sunlight. If grown in full sun, the plant’s fronds and foliage may become scorched or turn brown. For optimal growth, it is recommended to provide the fern with about 3-4 hours of direct sunlight a day. However, if the plant is placed in a sunny area it should be monitored closely as too much direct sun can cause damage. Watering should also be adjusted accordingly, providing the fern with more water if it is in an area of direct sun during warmer months, but reducing the amount during periods of cooler weather and less sun.

Cinnamon fern (Osmundastrum cinnamomeum) benefits from regular pruning to keep the plant looking neat and to avoid overcrowding of the area. Pruning should be done as needed, usually about once a year in the early spring. Start by deadheading or removing any spent or brown fronds at the basal. If necessary, remove any additional leaves and fronds that appear overcrowded or become too long. During the growing season, remove any spent flowers and seed heads immediately. When pruning, take care not to cut off the newly developing fronds. Depending on the size and shape of the fern, it may also be necessary to cut some stems back to maintain a non-weedy look. The best tool to use for pruning cinnamon ferns is a pair of clean, sharp scissors.
