Sticherus cunninghamii, also known as umbrella fern, is a New Zealand endemic fern.
Umbrella fern typically shows good resistance to disease and faces relatively few insect pests. Its care is regarded as difficult because it needs a consistently moist environment and frequent watering. At the same time, the roots can rot if the plant is overwatered or the surroundings lack adequate ventilation. Umbrella fern is better suited to those with some growing experience, since most people can keep it alive for a period of time. Nonetheless, the plant may struggle to thrive and its leaves can dry out and become less healthy as time passes.
How to keep Sticherus Cunninghamii.
Light
Umbrella fern comes from habitats such as forest understories or rocky areas that provide natural shade. It prefers Full Shade but can tolerate Partial Sun.
Water
Originating from humid environments, the umbrella fern thrives best in conditions with consistent moisture and high humidity, although it can tolerate moderate drought. To keep it looking lush, water the plant twice a week. As an understory plant, the umbrella fern is well-suited for indoor environments where moisture levels can be carefully managed. Its delicate fronds require conditions that mimic its naturally moist habitat.
Temperature
Umbrella fern grows well in forest underbrush. It is very sensitive to temperature and humidity, and high heat, dry conditions, and strong sunlight can all make the plant uncomfortable. In summer it needs adequate shade and a very humid environment. Generally, Umbrella fern does not require special care in winter, but prolonged dryness during the winter can still kill it.
Pruning
To promote the growth of your umbrella fern, it's best to prune it in early spring. Start by trimming the dead fronds at the base to encourage new shoots. Be careful not to over-prune, as this can cause stress to the plant. Regularly removing old growth will improve air circulation, reduce the risk of disease, and enhance the plant's appearance and vigor.
Pot & Repot
When repotting an umbrella fern, select a pot 1-2 inches (2.5–5.1 cm) larger that has plenty of drainage. Use a well-draining potting mix. Repot in spring or fall, making sure the root ball sits slightly lower than the rim of the flower pot. Water thoroughly after repotting and place the plant in a warm spot with indirect sunlight.
