In English, it is commonly referred to as the paper mulberry due to its use in papermaking. The plant also has other names such as tapa cloth bark, paper bark tree, and wauke in Hawaii.
Uses
The most notable use of Broussonetia papyrifera is for papermaking. The plant's bark contains long fibers that are strong and flexible, making them ideal for producing high-quality paper and tissue. The inner bark is also edible and has a sweet, nutty flavor. In Asia, the bark is sometimes roasted or boiled to extract its nutritious juices, which are then mixed with other ingredients to make a healthful drink.
Aside from papermaking and food consumption, Broussonetia papyrifera has medicinal properties. In traditional Chinese medicine, the plant is used to treat various ailments such as coughs, asthma, and high blood pressure. The plant's leaves and roots have also been used in folk medicine to heal wounds and alleviate fever and inflammation.
General Appearance
Broussonetia papyrifera is a deciduous tree or shrub that can grow up to 10 meters tall. It has a broad, rounded crown and a thick trunk. The plant has large, lobed leaves that are 15-20 cm long and 10-15 cm wide. The leaves are dark green on the top and light green on the bottom. The flowers are small and inconspicuous, and the plant's fruits are small, round aggregates that turn from green to red when mature.
The bark of Broussonetia papyrifera is smooth, light brown, and peels off in thin layers. The bark's inner layer is fibrous and can be used to make paper and textiles. The plant prefers moist and well-drained soils and is commonly found in low-lying areas such as riverbanks, hillsides, and forest edges.
Light Requirements
Broussonetia papyrifera (L.) L'Hér. ex Vent. typically thrives in direct sunlight but can still grow under partial shade. The plant requires at least six hours of direct sunlight per day to ensure healthy growth.
Temperature Requirements
The plant can endure a wide range of temperatures ranging from hot summers to cold winters. Broussonetia papyrifera (L.) L'Hér. ex Vent. can grow well in temperatures ranging from 15°C to 35°C. The plant cannot tolerate frost and therefore should not be exposed to temperatures below -5°C.
Soil Requirements
Broussonetia papyrifera (L.) L'Hér. ex Vent. thrives is well-drained, loamy soil. The soil shouldn't be too dense or too porous, and it must have a pH between 6.0 and 7.0. The plant needs a soil that can retain moisture, so it can grow optimally, but not waterlogged. Adequate drainage should be provided to avoid waterlogging, which can cause root rot. Additionally, the plant prefers soils rich in organic matter and nutrients.
Cultivation Methods
Broussonetia papyrifera (L.) L'Hér. ex Vent., commonly known as paper mulberry, is a fast-growing tree that prefers a warm and humid climate. It can be propagated through seeds or cuttings; however, cuttings are more commonly used for cultivation. This plant requires well-draining soil and a sunny location with partial shade. It is also important to provide support for young plants to prevent them from bending and breaking during strong winds.Watering Needs
Paper mulberry trees require regular watering, especially during the first few months after planting. The soil should be kept moist but not waterlogged. It is recommended to water the plant deeply once a week or more depending on the weather conditions. During hot and dry weather, the plant may require more frequent watering.Fertilization
Applying fertilizer to paper mulberry trees can promote healthy growth and lush foliage. Fertilizers high in nitrogen are recommended to be applied during the growth period, especially in the spring and summer. It is important not to over-fertilize the plant as it can lead to weak growth and susceptibility to pests and diseases.Pruning
Pruning the paper mulberry tree can help maintain its shape and reduce its overall size. However, it is recommended not to prune too much as it can cause stress to the plant. Dead or diseased branches should be removed to prevent the spread of disease. Pruning should be done during the dormant season in late winter or early spring. It is important to use clean and sharp pruning tools to prevent damage to the plant.Propagation of Broussonetia papyrifera (L.) L'Hér. ex Vent.
Broussonetia papyrifera (L.) L'Hér. ex Vent., commonly known as the paper mulberry, can be propagated through several methods.
Seed propagation
The most common method of propagating Broussonetia papyrifera is through seeds. The seeds of this plant have a hard outer coat and can take several weeks to germinate. To propagate through seeds, collect the ripe seeds in the fall and sow them into a well-draining soil mixture. Keep the soil moist and warm. Once the seeds have germinated, transplant them into individual containers.
Air layering
Air layering is another way to propagate Broussonetia papyrifera. In this method, a small cut is made in the stem and the wounded area is wrapped with sphagnum moss and plastic wrap. Once roots have formed, the rooted section is cut from the plant and planted in a container with well-draining soil mix.
Cuttings propagation
Broussonetia papyrifera can also be propagated with cuttings from the stem or branches of the plant. Cuttings should be taken from new growth, and should be at least 6 inches long. The cuttings should be dipped in rooting hormone and placed in well-draining soil mixture. Keep the soil moist and warm to promote the growth of roots.
Propagation of Broussonetia papyrifera through these methods can be an easy way to obtain new plants, and can be done in the spring or early summer when the plant is actively growing.
Disease and Pest Management for Broussonetia papyrifera (L.) L'Hér. ex Vent.
Broussonetia papyrifera, commonly known as Paper Mulberry, is a deciduous tree that belongs to the Moraceae family. It is cultivated for its bark, which is used to produce paper, clothing, and other items. Like all plants, Paper Mulberry is prone to pests and diseases that can affect its growth and productivity. It is essential to understand common diseases and pests that affect Paper Mulberry and ways to manage them.
Common Diseases of Broussonetia papyrifera
Paper Mulberry is vulnerable to various diseases, some of which are fungal, bacterial, and viral. A thorough understanding of these diseases can help to prevent and manage them.
Leaf Spot
One common disease that affects Paper Mulberry is leaf spot. Leaf spot appears as black or brown spots on the leaves and is caused by various fungi. This disease can cause defoliation, making the plant vulnerable to other infections. To manage leaf spot, remove and destroy the infected leaves and apply a fungicide.
Anthracnose
Anthracnose is another fungal disease that can affect Paper Mulberry. It causes dark, irregular spots on the leaves, stems, and fruits. The disease can cause defoliation and stunted growth of the plant. To manage anthracnose, prune the infected parts, improve air circulation, and apply a fungicide.
Powdery Mildew
Powdery mildew is a fungal disease that forms a white, powdery coating on the leaves and stems of Paper Mulberry. The disease can cause leaf yellowing, curling, and falling off. To manage powdery mildew, prune the infected branches and apply a fungicide.
Common Pests of Broussonetia papyrifera
Paper Mulberry is also prone to pests that can cause damage to the plant and reduce productivity. Understanding these pests can help manage them effectively.
Bagworm
Bagworms are common pests of Paper Mulberry. They attach silk bags to the branches, which they use for protection. Bagworms cause defoliation and weaken the plant. To manage bagworms, remove the silk bags and apply an insecticide.
Japanese Beetle
Japanese beetles are destructive pests that feed on the leaves, flowers, and fruits of Paper Mulberry. They cause skeletonization of the leaves and bud drop. To manage Japanese beetles, handpick them and drop them into soapy water or apply an insecticide.
Mites
Two-spotted mites are common pests of Paper Mulberry. They cause yellowing, curling, and falling of leaves and a decrease in productivity. To manage mites, apply a miticide and keep the plant hydrated and well-maintained.
In conclusion, Paper Mulberry is prone to various diseases and pests that can affect its productivity. Understanding common diseases and pests and ways to manage them is crucial for the plant's health and growth.
