The tree can go up to a height of 10-20 meters and has a slender trunk with grey or blackish, rough bark. The leaves are oblong, elliptic, and have a shiny dark green color with a pointed leaf tip. The leaves are approximately 3-4 inches long and have a horn-like shape that gives the tree its common name Horn-leaved. The flowers appear in clusters and are small, greenish-yellow, and unisexual. The fruit of the tree is small, round, and woody known as drupes or capsules.
Common Uses:
The tree is used for medicinal purposes by many indigenous communities in the regions where it grows. The bark of the tree is used as a traditional medicine in treating gastrointestinal diseases, respiratory ailments, and skin conditions. The leaves are sometimes used to relieve fever, headache, and burning sensation. The seed oil is used to treat rheumatism, and other ailments.
The wood of Suregada ceratophora is strong and hard and is used for making furniture, tool handles, and indoor flooring. The tree is also known to have ornamental purposes, and the beautiful flowers and horn-like leaves make the tree an attractive landscaping addition.
Light Requirements
Suregada ceratophora Baill. is a tropical plant that thrives in bright but indirect light. It can also tolerate partial shade conditions. It would be best if you placed it in an east or west-facing window with filtered sunlight for maximum growth and development. However, direct sunlight can burn the plant's leaves; therefore, avoid placing it in intense sunlight.
Temperature Requirements
This tropical plant needs warm temperatures to grow well. The ideal temperature range for Suregada ceratophora Baill. is between 60 and 85 °F (15 and 29°C). It cannot tolerate freezing temperatures, so make sure to keep it in a room with a constant temperature. During winter months, keep it away from drafty windows and doors, which can cause the temperature to drop rapidly.
Soil Requirements
The Suregada ceratophora Baill. plant prefers a well-draining soil mix that can hold moisture without becoming waterlogged. A mixture of potting soil, peat moss, perlite, and sand can create an ideal soil blend for this plant. It also likes slightly acidic soils with a pH range of 5.5 to 6.5. If the soil is too acidic, you can use lime to increase the pH level. However, avoid using alkaline soil or adding fertilizers that contain high amounts of nitrogen, which can damage the plant's roots.
Cultivation Methods
Suregada ceratophora Baill., commonly known as the Othalanga tree, can be grown from seeds or cuttings. It is best to plant the seeds immediately after they are harvested as they lose viability quickly. The plant prefers well-draining soil with good organic content and requires regular watering during the growing season. It can tolerate partial shade, but full sun exposure is ideal.
Watering Needs
While the Othalanga tree requires regular watering during the growing season, it is important not to over-water as it can cause root rot. The soil should be moist to the touch, but not waterlogged. In the winter months, the plant can survive with less frequent watering, but it should not be allowed to dry out completely.
Fertilization
A balanced fertilizer containing equal measures of nitrogen, phosphorus, and potassium is recommended for the Othalanga tree. Fertilizer should be applied every four to six weeks during the growing season starting in the spring and ending in the fall. Avoid over-fertilizing, as this can cause the plant to produce excessive foliage at the expense of flowers or fruit.
Pruning
Pruning is essential to maintain the shape and size of the Othalanga tree. It is best to prune in the late winter or early spring, before new growth appears. Dead or damaged branches should be removed immediately as they can attract insects or provide an entry point for diseases. New growth should be trimmed to encourage branching and density of the foliage.
Propagation Methods for Suregada ceratophora Baill.
Propagation of Suregada ceratophora Baill. can be done both by seeds and vegetative methods. The plant can also be propagated through cuttings or air layering techniques.
Propagation through Seeds
Seeds of Suregada ceratophora Baill. should be collected during the months of October and November. They should be sown immediately after collection, as the seeds lose their viability rapidly.
The seeds should be soaked in water for 24 hours before plantation. The plantation can be done in well-prepared nursery beds filled with a mixture of soil and manure in 1:1 ratio. The seeds should be sown at a depth of 2-3 cm and kept moist through regular watering. Germination occurs within 3-4 weeks, and the seedlings can be transplanted once they reach the height of approximately 15 cm.
Vegetative Propagation
Suregada ceratophora Baill. can also be propagated through vegetative methods such as cuttings or air layering.
Cuttings taken from mature plants should be around 25-30 cm long with a diameter of approximately 1 cm. The cuttings should be treated with rooting hormone powder and planted in a mixture of sand, soil, and manure in equal parts. The cuttings should be kept moist and shaded, and roots will start to develop within a month. The rooted cuttings can be transplanted to permanent sites.
Air layering is another method used in propagating Suregada ceratophora Baill. This method is usually used to propagate large trees. The bark should be wounded, and rooting hormone should be applied to the wound. A ball of soil is tied around the wound using polythene sheets to maintain moisture. Roots will develop in about four weeks, and the rooted branch can be cut below the ball and transplanted.
Disease and Pest Management for Suregada ceratophora Baill.
Suregada ceratophora Baill., also known as the White Teak Tree or Jalari in Hindi, is a medicinal plant commonly found in India, Sri Lanka, and Myanmar. The plant is used to cure various ailments, including skin diseases, cancer, and snake bite. However, like any other plant, Suregada ceratophora Baill. is prone to pests and diseases, which can significantly affect its growth and yield.
Common Pests
The following are common pests that can attack Suregada ceratophora Baill.:
- Tea Mosquito Bug: This pest pierces plant tissues and sucks sap, resulting in deformed leaves and stunted growth. To manage this pest, use insecticides containing neem oil or spray hot water on the affected areas.
- Leaf-Eating Caterpillar: This pest feeds on young leaves and shoots, causing defoliation and reduced growth. Physical removal of the caterpillar or use of insecticides like diazinon is effective in managing this pest.
- Mealybug: This pest secretes a waxy substance that covers the plant, making it difficult for the plant to photosynthesize. Use insecticides like malathion to manage mealybugs.
Common Diseases
Suregada ceratophora Baill. can also be affected by various diseases, including:
- Leaf Spot: This fungal disease appears as small brown spots on the leaves, which eventually turn yellow. The disease can be managed by pruning affected leaves and applying fungicides like copper oxychloride.
- Root Rot: This disease is caused by overwatering and poor drainage, leading to wilting and eventual death of the plant. To manage root rot, ensure proper watering and drainage and apply fungicides like carbendazim.
- Powdery Mildew: This fungal disease appears as a white powdery substance on the leaves and stems, leading to stunted growth. Manage this disease by pruning affected leaves and applying fungicides like potassium bicarbonate.
Overall, managing pests and diseases in Suregada ceratophora Baill. involves a combination of preventive and curative measures. Regular inspection of plants, proper sanitation, and use of disease-resistant varieties can significantly reduce the incidence of pests and diseases. In cases of severe infestations or infections, use of chemical control measures like insecticides and fungicides may be necessary.
