How to Propagate Calathea Roseopicta? A Detailed Guide to Common Propagation Methods

Calathea roseopicta has many advantages and is loved by many people. It can now be seen in many regions of our country, and as market demand grows day by day, some enterprises have already used greenhouses for year-round production, achieving good economic benefits. Artificial propagation of Calathea roseopicta can also use division or cuttings. The editor will give you a brief introduction.

Calathea roseopicta

Division is best done after the temperature warms up in spring. Vigorously growing plants can be divided once every 1-2 years. Cut the clustered plant into several clumps along the direction of underground rhizome growth, then pot them separately, place them in a relatively shady spot for care, and manage them by routine methods after roots develop.

Cuttings can also be taken from elongated stem sections with nodes. Cuttings can be taken during the plum rain season: cut the internodes from the upper part of the mother plant, insert them into leaf mold or peat, and pot them after roots develop.

Propagation Methods of Calathea Roseopicta; Differences Between Calathea Roseopicta and Calathea Picturata

Calathea roseopicta is a very attractive indoor foliage plant. Mature Calathea roseopicta plants can reach 30-80 cm in height, and artificial cultivation is not very difficult. So how do you propagate Calathea roseopicta? What is the difference between Calathea roseopicta and Calathea picturata?

I. Propagation Methods of Calathea Roseopicta

1. Division propagation: Calathea roseopicta is best divided after the temperature warms up in spring. Vigorously growing plants can be divided once every 1-2 years. Cut the clustered plant into several clumps along the direction of underground rhizome growth, then pot them separately, place them in a relatively shady spot for care, and manage them by routine methods after roots develop.

2. Cutting propagation: Cuttings can be taken during the plum rain season. Cut the internodes from the upper part of the mother plant, insert them into leaf mold or peat, and pot them after roots develop. During the growing season, mist the leaves frequently, fertilize once a month, and place them in shade in midsummer to avoid strong direct sunlight. Water must not accumulate in the pot, and yellow and withered leaves should be cut off promptly. In winter, they need plenty of sunlight and watering should be appropriately reduced.

II. Differences Between Calathea Roseopicta and Calathea Picturata

The upper surface of Calathea roseopicta leaves is pure green, while the upper surface of Calathea picturata leaves has large areas of yellow or white stripes and patches.

Calathea roseopicta, also known as Calathea roseopicta, has upright branches and leaves, with green upper leaf surfaces and red undersides. It is very attractive and is a good indoor foliage plant. It is commonly propagated by division or cuttings. For division, in April-May each year, lift out the tightly clustered plant and pull it apart into small clumps for planting and care. For cuttings, during the plum rain season, cut the internodes from the upper part of the mother plant, insert them into leaf mold or peat, and pot them after roots develop. During the growing season, mist the leaves frequently, fertilize once a month, and place them in shade in midsummer to avoid strong direct sunlight. Water must not accumulate in the pot, and yellow and withered leaves should be cut off promptly. In winter, they need plenty of sunlight and watering should be appropriately reduced.

Calathea picturata, also known as Calathea picturata, belongs to the family Marantaceae and the genus Ctenanthe. It is a perennial herb, 30-60 cm tall, with underground rhizomes, growing in clumps. Leaves grow from the roots; the leaves are long elliptical-lanceolate, with entire margins; the leaf surface is dark green with pale green, white to pale pink feather-like variegation, and the petiole and leaf underside are dark red. The best growing medium is humus soil or sandy loam, with good drainage required. Aging leaves should be cut off at any time. It prefers high temperature and high humidity. The leaf color is bright and gorgeous, it is shade-tolerant, and it grows densely, making it suitable for clump planting in shady garden areas, as ground cover or small potted plants, and it is a high-grade indoor plant. Propagation and cultivation can use division, with spring being the suitable time.

Cultivation Methods of Calathea Roseopicta

Precautions for Cultivating Calathea Roseopicta

1. Calathea roseopicta is an excellent shade-loving indoor foliage plant. In hot summer, prevent exposure to sunlight and shade 70%-80% of the light, otherwise damage is likely to occur;

2. If air humidity is low and the potting soil is dry, the leaf edges will turn yellow and scorch; in addition, direct sunlight can also cause the leaf edges to turn yellow and scorch;

3. For Calathea roseopicta, be sure to repot once every 1-2 years.

Division

Calathea is generally propagated by division. Propagation is most ideal when the spring temperature is around 20°C, but as long as the temperature and humidity are suitable, it can also be done year-round. When propagating, use a sharp knife to cut apart the root tubers with stems and leaves or leaf buds; for small-scale propagation, the cut root tubers with stems, leaves and leaf buds can be placed directly into clay pots; for large-scale propagation, they should be placed on a seedbed; when temperature and humidity do not meet the requirements, cover with plastic film; be sure to make the temperature inside the film reach 20-28°C and the humidity above 80%.

Cuttings

For cutting propagation of Calathea roseopicta, terminal young shoots are generally used. The cuttings are 10-15 cm long. Depending on leaf size, retain one-third or one-half of the leaf. Treat the cuttings with 500 ppm naphthaleneacetic acid for 2-3 seconds; indoleacetic acid, indolebutyric acid and ABT rooting powder can also be used.

After treatment, insert the cuttings into the seedbed, preferably at a spacing of 5 x 10 cm. Cover with a plastic film arched shed, and manage them in the same way as division propagation. Cutting propagation can be carried out at any time when the temperature is not lower than 20°C. The cuttings root in 30-50 days; however, the survival rate of cuttings is not as high as that of division propagation; it is generally around 50%.

Uses and Purposes of Calathea Roseopicta

Ornamental Value

Calathea has underground rhizomes or tubers, and the leaves are single and relatively large. In addition to the open leaf sheath at the base of the leaf, there is also a noticeably swollen joint where the leaf blade connects to the petiole, called the "pulvinus," which contains water-storage cells and functions to adjust leaf orientation; that is, at night when water is sufficient the leaves stand upright, and during the day when water is insufficient the leaves spread out. This is a characteristic of plants in the family Marantaceae. In addition, some Calathea also have "sleep movement," that is, the leaves spread out during the day and fold at night, which is very peculiar.

Indoor Arrangement

Because Calathea roseopicta is fairly shade-tolerant and has beautiful leaf color, it can be planted directly in corner areas of public places such as hotels, shopping malls and large venues for permanent arrangement. However, during cultivation and management, light should be appropriately supplemented and the leaves should be misted regularly to increase air humidity.

Potted Plants and Cut Foliage

Because Calathea roseopicta has a beautiful plant shape and colorful leaf surfaces, and also has strong shade tolerance, and cultivation and management are relatively simple, it is used for indoor potted ornamental display and is one of the most famous indoor foliage plants in the world. Large varieties can be used to decorate the halls of hotels and shopping malls, while small varieties can accent balconies, living rooms, bedrooms and so on. During cultivation and management, after being displayed for a period of time, it should be placed in a brighter place such as a balcony or windowsill to enhance light, which is beneficial for long-term enjoyment. Because the leaf color is colorful and has striking markings, it is a high-grade cut foliage material and can be used directly in flower arrangements or as filler material for flower arrangements.
