Dryopteris erythrosora, commonly known as the Autumn fern, is a hardy plant that can grow well outdoors in the UK. Here are some care instructions that can help keep your Dryopteris erythrosora healthy:
-
Watering: The Autumn fern prefers moist soil, so water it regularly during the growing season, especially during hot and dry weather. However, avoid overwatering, as the plant does not tolerate waterlogged soil.
-
Soil: The Autumn fern prefers well-draining, acidic soil with plenty of organic matter. If your soil is heavy and clay-like, consider adding some compost or peat moss to improve its texture.
-
Light: The Autumn fern grows best in partial shade, although it can tolerate full shade or full sun with adequate moisture.
-
Fertilizer: You can fertilize your Autumn fern with a balanced fertilizer once or twice during the growing season. However, avoid over-fertilizing, as this can lead to burnt foliage.
-
Pruning: Remove any dead or damaged fronds as soon as you notice them. You can also prune the plant in early spring to promote new growth.
-
Winter care: In the UK, the Autumn fern is hardy and can survive winter temperatures. However, you may want to provide some protection from cold winds and frost by covering the plant with a layer of mulch.
