Light Requirements
Barleria alata S.Moore var. alata thrives best in bright light conditions. The ideal level of light that promotes healthy growth should be between 4,000 and 6,000 lux. The plant can also tolerate low light conditions but won't flower as often or as profusely as those grown under bright light
Temperature Requirements
The plant thrives best in warm temperatures between 18°C and 23°C. It can still survive at lower temperatures but may not grow as vigorously. It's essential to keep the plant away from cold drafts as this can lead to stunted growth and yellow leaves.
Soil Requirements
Barleria alata S.Moore var. alata prefers well-draining soil that's rich in organic matter. A soil mixture of peat moss, perlite, and coarse sand in equal portions is ideal for the plant. The pH of the soil should range from 6.0 to 7.5, which is slightly acidic to slightly alkaline. The plant may suffer from root rot in waterlogged soils, so ensure that the container has sufficient drainage holes.
Cultivation
Barleria alata S.Moore var. alata, commonly known as the Philippine violet, grows best in well-draining soil and mild temperatures of 60-85°F (15-30°C). It is recommended to plant it in a sunny spot with partial shade, especially in areas with hot climates.
If planting in a pot, make sure the pot is at least 8 inches deep and filled with well-draining soil mixed with sand and peat moss to promote good drainage. Plant roots should be covered with soil and watered thoroughly.
Watering Needs
The Philippine violet requires moderate watering during the growing season, which is typically from spring to fall. Water the plant thoroughly when the topsoil feels dry to the touch, but do not allow it to become waterlogged as this can cause root rot. Reduce watering during the winter months.
Fertilization
Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium, to promote healthy growth. Fertilize the Philippine violet every two weeks during the growing season, and reduce fertilization during the winter months.
Pruning
Pruning is essential to keep the Philippine violet compact and bushy. Pinch back new growth regularly to promote branching and bushiness. Also, trim off old, dead, or yellowing leaves and cut back any damaged or overgrown stems to keep the plant healthy and attractive.
Propagation of Barleria alata S.Moore var. alata
Barleria alata S.Moore var. alata is a plant that can be propagated by several methods:
Seed propagation
The easiest and most common method of propagating Barleria alata S.Moore var. alata is through seed. To do this, the plant must produce healthy seeds that are collected and sowed in well-prepared soil. It is recommended to sow the seeds in spring or summer, as this is the period when they usually germinate faster. Care must be taken to keep the soil moist until the seeds germinate, and the temperature should be kept between 20-25 C°. Once the seeds have germinated, the plants can be transferred to individual pots and then to a well-drained garden bed.
Cutting propagation
Another way to propagate Barleria alata S.Moore var. alata is through cuttings. This method is more suitable for those who want to get plants that are genetically identical to the mother plant. Cuttings should be collected during early spring or early autumn from the plant's semi-hardwood stems. The cuttings should be roughly 10 cm long and with two or three leaves. The lower part of the cutting should be dipped in rooting hormone and planted in well-prepared soil. The soil should be kept moist, and the plant should be placed in a warm and shady place until it begins to root. Once roots form, the plant can be transferred into an individual pot or directly into a garden bed.
Division propagation
Barleria alata S.Moore var. alata can also be propagated through division. This method involves separating the plant's roots and stems into smaller pieces. It is recommended to do this in early spring, before the plant resumes growth. The plant should be carefully lifted out of the soil and separated into smaller sections, each with their own root system. The sections can be potted in well-prepared soil and kept in a shaded and warm location until they are established. Once they have established themselves and are actively growing, they can be transferred into a garden bed.
Disease Management
Barleria alata S.Moore var. alata can fall victim to various diseases, including fungal infections, bacterial infections, and viruses. The plant's leaves may develop spots, turn yellow, wilt, or drop, affecting the plant's overall health. To address these diseases, preventative measures are vital. One approach is ensuring that the plant has adequate air circulation by planting it in well-spaced rows. Other measures involve proper sanitation, like pruning and disposing of any infected parts. Applying appropriate fungicides and bactericides, as well as using virus-free seedlings, can also help manage the diseases.
Pest Management
Barleria alata S.Moore var. alata can also be affected by various pests, including aphids, whiteflies, spider mites, and thrips. These pests can cause direct damage to the plant's leaves and stems, weakening the plant's growth, and leaving it susceptible to diseases. To manage them, one approach is to use organic methods such as using beneficial insects to control the pest population. Another method is to apply horticultural oil or insecticidal soap to the plant leaves. Other measures involve keeping the area around the plant clean and properly disposing of any fallen leaves or stems that can harbor pests.
