watering

Sweet fern should be watered once a week. Depending on the weather conditions, you may need to water your plant more often. For example, during hot, dry and windy weather, you should increase your watering schedule. Use room-temperature water and water your sweet fern until the soil is saturated but not soggy. Allow the top layer of soil to dry out between waterings to avoid root rot. Overwatering can cause root decay and can even be fatal to sweet fern.

sunlight

Sweet fern grows best in sunny, dry conditions and requires full or partial sunlight for best growth and development. For optimal growth, sweet fern should receive approximately 6 to 8 hours of sunlight a day, split up into 2 to 4 hours in the morning and 2 to 4 hours in the afternoon. It may also benefit from being shaded in the hottest part of the day during the summertime. Additionally, sweet fern can tolerate partial shade, and will still grow in areas that receive more than 6 hours of indirect sunlight a day.

pruning

Sweet fern should generally be pruned in late winter or early spring when the new growth begins to emerge. To prune correctly, first remove any dead, damaged, or diseased branches. Then, remove any overcrowded or crossed branches to allow for better air circulation. Finally, if necessary, lightly trim the shrub to the desired shape. Light pruning is recommended to keep its natural shape. Avoid cutting back too much as it can damage the plant.
