Tmesipteris tannensis is a fern ally endemic to New Zealand. It is usually epiphytic on trees and tree ferns, but is occasionally terrestrial. An example of occurrence of T. tannensis within a tiered phytocoenosis is in Central Westland of South Island, New Zealand. These forests are the most extensive continuous podocarp/broadleaf forests in New Zealand. The overstory includes miro, rimu and mountain totara. The mid-story includes tree ferns such as Cyathea smithii and Dicksonia squarrosa, whilst the lowest tier and epiphytic associates include Asplenium polyodon, Astelia solandri and Blechnum discolor along with T. tannensis.
Fork fern typically has strong resistance to disease and encounters relatively few insect pests. Its care is considered difficult because it requires a moist environment and frequent watering. However, the roots can rot if it is overwatered or if the environment lacks good ventilation. Fork fern is suitable for people with some growing experience, as most people are able to keep it alive for a certain amount of time. Nevertheless, it may have trouble thriving and its leaves can dry out and become less healthy over time.
How to keep Tmesipteris Tannensis.
Light
Fork fern is native to habitats such as forest understories or rocky areas that provide natural shade. It prefers Full Shade but can tolerate Partial Sun.
Temperature
Fork fern does best in forest undergrowth. It is very sensitive to temperature and moisture; heat, dryness, and strong sunlight can all distress the plant. In summer it needs sufficient shade and a humid atmosphere. Generally it does not demand special care during winter, but a prolonged dry period in winter can still be fatal.
