The screw pine is an evergreen woody foliage plant with leaves arranged in a spiral.

The screw pine is an evergreen woody foliage plant of the genus Dracaena, also known as the spiral dracaena. Its stem is upright and straight, and its slender leaves are arranged in spiral layers around the stem, looking from a distance like a tightened screw thread, which is how it got its name. The whole plant has deep green, glossy leaves, a neat shape, and a long ornamental period.

In terms of care, the screw pine likes a warm, humid, bright, semi-shaded environment; it fears both strong direct sunlight and cold. In summer, avoid direct scorching sun, and in winter pay attention to keeping it warm; when room temperature is low, reduce watering to help it overwinter smoothly. The soil is best loose, breathable, and well-drained, and watering should follow the principle of watering when dry and stopping when wet; long-term water accumulation in the pot can easily cause root rot. Usually, you can frequently spray water on the leaves and surrounding area to maintain a certain air humidity, and the leaf color will become more glossy.

Propagation is mostly by cuttings: cut stem sections with leaves and insert them into a moist medium, keep the environment warm and humid, and once they root and survive they can be planted separately. During the growing season, a small amount of diluted liquid fertilizer can be applied, paying attention to light and frequent feeding; concentrated fertilizer can easily damage the roots.

A common problem in home care is yellowing and drying leaf tips, which is mostly related to overly dry air, improper watering, or low temperatures, and can be adjusted promptly according to the environment. As long as light, temperature, and water and fertilizer management are appropriate, the screw pine can remain green all year round, and it is a very popular foliage potted plant for indoor places such as living rooms and offices.
