Azolla rubra, known commonly as red azolla and Pacific azolla, is a species of aquatic fern native to Australia and New Zealand. In New Zealand, it is also known by its Māori names returetu, roturotu, kārearea and kārerarera.
Red azolla typically resists disease well and faces relatively few insect pests. Its care is regarded as difficult because it needs a moist environment and frequent watering. Nevertheless, the roots can rot if they are overwatered or if the environment lacks good ventilation. Red azolla is appropriate for people with some growing experience, since most individuals can keep it alive for a certain amount of time. However, it may struggle to thrive, and its leaves can dry out and become less healthy over time.
How to keep Azolla Rubra.
Light
Red azolla comes from environments such as forest understories or rocky regions that provide natural shade. It favorably thrives in full shade sunlight conditions, but it can also stand partial sun exposure.
Temperature
Red azolla flourishes robustly within the confines of forest groves. This plant is extremely responsive to changes in temperature and moisture, and extreme heat, arid conditions, and harsh sunlight could potentially distress Red azolla. In the summertime, it demands an adequately shaded location and a high-moisture setting. On the whole, Red azolla doesn't need extraordinary attention during the winter, yet a lengthened period of winter dryness can prove deadly for the plant.
