Light Requirements
Thouinia striata Radlk. var. striata thrives in full to partial sunlight, making it ideal for planting in bright areas. However, it can also tolerate partial shade for short periods, making it adaptable to different lighting conditions.
Temperature Requirements
Thouinia striata Radlk. var. striata is a tropical plant that requires warm temperatures to grow well. The ideal temperature range for its growth is between 21 to 27 °C. It cannot tolerate frost or freezing temperatures, which can damage or kill the plant.
Soil Requirements
Thouinia striata Radlk. var. striata thrives in well-drained, slightly acidic soil with a pH range of 5.5 to 6.5. It prefers sandy or loamy soil that is rich in organic matter and has good drainage. It cannot tolerate waterlogged soil, which can cause root rot or other diseases.
Cultivation
Thouinia striata Radlk. var. striata is a tropical plant that requires warm temperatures and consistent humidity. It is best grown in locations that receive direct sunlight in the morning and indirect sunlight in the afternoon. The plant can also tolerate partial shade, but it will have slower growth.
The plant prefers well-draining soil that has a pH level of 6 to 7. It can be propagated through seeds or stem cuttings. Seedlings will take around three years to reach maturity, while stem cuttings will take around two years before significant growth can be seen.
Watering Needs
Thouinia striata Radlk. var. striata requires consistent watering during the growing season. Water the plant when the top inch of soil is dry to the touch, and be sure to avoid overwatering. Overwatering can lead to diseases and root rot.
The plant can tolerate short periods of drought, but it will not survive extended periods without water. Watering frequencies will vary depending on the plant's size, location, and environmental factors such as temperature and humidity.
Fertilization
Fertilization is essential in maintaining healthy growth for Thouinia striata Radlk. var. striata. The plant should be fertilized once every two months during the growing season, using a balanced fertilizer that is rich in nitrogen, phosphorus, and potassium.
Be sure to follow the manufacturer's instructions when applying fertilizer. Too much fertilizer can damage the plant's roots and lead to stunted growth. If using a slow-release fertilizer, apply it once every six months.
Pruning
Thouinia striata Radlk. var. striata requires minimal pruning to maintain its shape and size. Pruning should be carried out during the dormant season, which typically occurs from late fall to winter.
Remove any dead or damaged branches, and trim the plant's canopy to promote fuller growth. Be sure to use clean, sharp pruning shears to avoid damaging the plant's bark.
If the plant has become too large, it can be pruned back by up to 25% of its total height. However, this should only be done every 2-3 years to avoid stressing the plant.
Propagation of Thouinia striata Radlk. var. striata
Thouinia striata Radlk. var. striata, commonly known as "Kolalumpit" or "Tenuis," is a slow-growing tree native to the Philippines. The plant is valued for its hardwood timber, which is used for furniture, construction, and carvings. Propagation of Thouinia striata Radlk. var. striata can be done through several methods:
Seed Propagation
Propagation through seeds is the most common method of reproducing Thouinia striata Radlk. var. striata. Mature seeds are collected from the tree during the fruiting season, which occurs from May to August. The seeds are then cleaned and soaked in water for 24 hours to soften the hard shell.
Once the seeds have been soaked, they are planted in a mixture of soil and sand. The seeds should be planted vertically, with the flat end facing downwards. The pots are then placed in a shaded area and watered regularly.
Grafting
Propagation by grafting is also possible for Thouinia striata Radlk. var. striata. This method is preferred for producing trees with desirable characteristics, such as a straight trunk or good timber quality.
Grafting is done by taking a scion from a mature tree and attaching it to a young seedling. The scion is cut at an angle and the seedling is cut in a similar manner. The two cuts are then joined together and wrapped tightly with grafting tape. The grafted plant is then placed in a shaded area and watered regularly.
Cuttings
Propagation through cuttings can also be done for Thouinia striata Radlk. var. striata, although this method is less common. Cuttings are taken from the tree during the dormant season, which occurs from October to November.
The cuttings should be 30-40cm in length and taken from the middle section of the stem. The leaves should be removed except for the topmost leaves. The cutting is then planted in a mixture of soil and sand and placed in a shaded area. The cutting should be watered regularly.
Disease and Pest Management for Thouinia Striata Radlk. var. Striata
Thouinia Striata Radlk. var. Striata is a tree species that is susceptible to various diseases and pests. Here are some of the most common diseases and pests and ways to manage them:
Diseases
Fungal infections: One of the most common diseases that affect Thouinia Striata Radlk. var. Striata is fungal infection. Fungi such as Fusarium and Phytophthora can cause root rot, which can lead to wilting and death of the plant. To manage this, avoid over-watering plants and ensure proper drainage. Fungicides may also be used to control the spread of the fungus.
Bacterial infections: Bacteria such as Xanthomonas are also known to cause leaf blight and stem rot in Thouinia Striata Radlk. var. Striata. To manage this, remove affected leaves to prevent the spread of the infection. Copper-based fungicides can also be used to control bacterial infections.
Viral infections: Viral infections are less common in Thouinia Striata Radlk. var. Striata, but they can still occur. Symptoms of viral infections include stunted growth and deformation of leaves. Unfortunately, there is no treatment for viral infections, and infected plants should be removed and destroyed to prevent the spread of the infection.
Pests
Spider Mites: Spider mites are common pests that can feed on plants and cause damage by sucking sap from leaves. Signs of infestation include yellowing and drying of leaves. To manage this, keep the leaves clean and avoid over-fertilizing. Insecticidal soap or neem oil could also be used.
Caterpillars: Caterpillars such as loopers can also cause damage to Thouinia Striata Radlk. var. Striata. They feed on the plant's leaves, leaving behind holes and chewed leaves. To manage this, remove caterpillars from the plant by hand and use Bacillus thuringiensis var. Kurstaki insecticide if necessary.
Aphids: Aphids are small insects that can feed on the sap of Thouinia Striata Radlk. var. Striata. They can cause yellowing and curling of leaves, as well as the growth of mold. To manage this, spray the plants with a strong jet of water to knock off the aphids or use insecticidal soap.
Proper care and maintenance of Thouinia Striata Radlk. var. Striata can help prevent the occurrence and spread of diseases and pests. Regularly monitoring the plants and taking appropriate actions can help ensure a healthy growth and development of the tree.
