Soil requirements
Pauridiantha paucinervis (Hiern) Bremek. subsp. paucinervis favors well-drained gritty soil. The soil should be slightly acidic with a pH level between 5.5-6.5. Moreover, it must include a high content of organic matter to promote healthy growth. Additionally, the soil must be rich in nutrients, and the addition of compost or animal manure can be helpful in achieving the nutrient requirements.
Cultivation methods
Pauridiantha paucinervis (Hiern) Bremek. subsp. paucinervis is a herbaceous plant that grows in moist areas, such as riverbanks and swamps. It requires planting in well-drained soils with rich organic matter content. Choose a location with partial shade to full sun exposure, where the plant receives at least 6 hours of sunlight per day. The ideal temperature range is between 18 to 22°C.
Watering needs
Being a plant that grows in wetlands, Pauridiantha paucinervis (Hiern) Bremek. subsp. paucinervis requires frequent watering to keep the soil moist. However, it is important to prevent the soil from becoming waterlogged, as it can cause root rot and other diseases. Water the plant once or twice a week, depending on the weather conditions and the soil type.
Fertilization
To promote the growth and development of Pauridiantha paucinervis (Hiern) Bremek. subsp. paucinervis, it is recommended to fertilize it regularly. Use a balanced fertilizer with equal parts of nitrogen, phosphorus, and potassium. Apply the fertilizer during the growing season, which usually starts in spring and ends in autumn. Avoid fertilizing the plant during winter.
Pruning
Pauridiantha paucinervis (Hiern) Bremek. subsp. paucinervis requires minimal pruning. Remove any dead or diseased leaves or stems, as soon as you detect them. This prevents the spread of diseases and promotes the growth of healthy foliage. If the plant becomes too bushy, you can selectively remove some stems to promote air circulation and sunlight penetration. However, avoid over-pruning, as it can weaken the plant and reduce its ability to produce flowers.
Propagation of Pauridiantha paucinervis subsp. paucinervis
Pauridiantha paucinervis subsp. paucinervis is a perennial plant that grows from an underground tuber. The plant can be propagated through various methods, including seed propagation, division, and tuber division.
Seed propagation
Seeds can be collected from mature fruits of the plant. To increase the chances of successful germination, the seeds can be soaked in warm water for 24 hours. Afterward, they should be sown in a well-draining potting mix and kept in a warm and humid environment. The seeds will typically germinate within one to two weeks.
Division
The plant can also be propagated through division. This method involves separating the underground tubers, making sure that each division has a bud or growth point. The divisions can then be planted in a well-draining potting mix and kept in a warm, humid environment until new growth appears.
Tuber division
Finally, tuber division is another method of propagating Pauridiantha paucinervis subsp. paucinervis. This method is similar to division, but instead of separating the entire plant, only a portion of the underground tuber is removed. The removed section should have a bud or growth point and can be planted in a well-draining potting mix. Like the other methods, it should be kept in a warm, humid environment until new growth appears.
Disease management
Pauridiantha paucinervis is susceptible to various foliar diseases such as anthracnose and leaf spot caused by fungal pathogens.
To manage anthracnose, it is important to remove infected leaves and destroy them immediately. Fungicides such as copper-based or sulfur-based can also be used to manage the disease. Application of fungicides should be done before the onset of rainy seasons or when the first disease symptoms are observed.
Leaf spot can be managed by practicing good sanitation such as removing infected leaves and planting disease-resistant cultivars. Application of fungicides can also be effective in controlling the disease.
Pest management
Some of the common pests that could affect Pauridiantha paucinervis include spider mites, mealybugs, and aphids.
Spider mites can be managed by spraying the plant with a high-pressure water jet to knock off the pests and their webs. The use of insecticidal soap or horticultural oil can also be effective, but care should be taken not to apply during the heat of the day or when the plant is under drought stress.
Mealybugs and aphids can be managed by releasing natural enemies such as ladybugs and lacewings. Another way to manage these pests is by applying insecticidal soap or neem oil. Care should be taken not to apply insecticides indiscriminately as this can lead to the development of pesticide-resistant populations of pests.
