New Zealand flax

New Zealand flax (Phormium 'Jester') should be watered once or twice a week depending on the weather conditions and the soil type. In warm, dry climates, water more often using a deep watering method. On hot days, you may need to water twice a day, particularly if there is no shade available to protect the plant from the heat. Water deeply, providing enough water to soak the root zone. Water until it runs freely from the bottom of the pot. During the fall and winter months, reduce the frequency of watering to once every 10-14 days.

New Zealand flax (Phormium 'Jester') thrives best when it receives at least 6 hours of sunlight each day. Early morning sun is especially beneficial. This species should be placed in an area that receives direct sunlight most of the day, but will also do quite well in partial shade. New Zealand flax will need protection from strong afternoon sun, which can be provided with shade cloth or other forms of light protection. Avoid placing New Zealand flax in deep shade or in a location with heavy foot traffic as it may not survive.

New Zealand flax (Phormium 'Jester') should typically be pruned once a year in late winter or early spring, before the start of the growing season. Pruning should involve removing dead or damaged leaves or stems. To further encourage bushiness and a neat, tidy appearance, some lightly pruning back of the thin, green leaves may be carried out at this time. This should be done delicately and sparingly to avoid damaging the leaves or stems. Overall, the amount pruned should not exceed 1-third of the plant's height or width.
