Growth conditions for Salacia pallescens Oliv.
Light: Salacia pallescens prefers partial shade to full sun. It can grow in full sun, but it may require more frequent watering to prevent dehydration.
Temperature: Salacia pallescens can tolerate a wide range of temperatures from 15°C to 35°C. However, it grows best in warm climates with temperatures above 20°C. Frost can damage the plant, so it should be protected during cold weather.
Soil: Salacia pallescens grows best in well-drained soils with good fertility. The pH of the soil should be between 5.5 and 6.5. The plant can tolerate acidic to slightly alkaline soils. It prefers soils that are rich in organic matter.
Water: Salacia pallescens requires moderate watering. The soil should be kept moist but not waterlogged. Overwatering can cause root rot, while under-watering can cause the leaves to wilt. Watering frequency should be reduced during the dormant season.
Fertilizer: Salacia pallescens benefits from regular fertilization. A slow-release granular fertilizer high in nitrogen, phosphorus, and potassium can be applied during the growing season. Alternatively, a liquid fertilizer can be applied every two weeks during the growing season.
Propagation: Salacia pallescens can be propagated from stem cuttings or by seed. Stem cuttings should be taken in the early spring and treated with rooting hormone before planting. The seeds should be planted in well-drained soil in a warm, bright location.
Cultivation of Salacia pallescens Oliv.
Salacia pallescens Oliv., commonly known as "Kra-jae-nee," is a woody climber species that thrives in tropical and subtropical regions. It usually grows in the wild, but it can also be cultivated. Here are some guidelines to cultivate Salacia pallescens Oliv.:
- Choose a location with partial to full sun exposure, and fertile, well-drained soil.
- Prepare the soil by adding organic matter and fertilizer before planting.
- Salacia pallescens Oliv. can be propagated by seeds or stem cuttings. If using seeds, soak them in water for 24 hours before planting.
- Plant the seeds or cuttings at a depth of 1-2 inches and 6-8 inches apart for cuttings and 12-18 inches apart for seedlings.
- Water the plant regularly, especially during the growing season, to keep the soil moist but not waterlogged.
- Provide support for the plant to climb, such as trellises or fences.
Watering Needs of Salacia pallescens Oliv.
Proper watering is essential to ensure the health and growth of Salacia pallescens Oliv. Here are some tips for watering:
- Water the plant deeply once a week during the dry season, and twice a week during the rainy season.
- Avoid overwatering as it can lead to root rot and other fungal diseases.
- Check the soil moisture level and adjust the watering schedule accordingly.
Fertilization of Salacia pallescens Oliv.
Fertilization is essential for the proper growth and development of Salacia pallescens Oliv. Here are some guidelines for fertilization:
- Apply a balanced fertilizer, such as 10-10-10, at the beginning of the growing season.
- Apply fertilizer again halfway through the growing season.
- Avoid over-fertilizing as it can lead to excessive vegetative growth and reduced fruiting.
Pruning of Salacia pallescens Oliv.
Pruning is necessary to control the size and shape of Salacia pallescens Oliv. Here are some guidelines for pruning:
- Prune the plant lightly at the end of the growing season to remove any dead or diseased branches.
- Prune to shape the plant during the dormant season to maintain its size and shape.
- Remove any crossing branches and those that grow inward.
- Prune the plant after fruiting to encourage new growth and fruiting for the next season.
Propagation of Salacia pallescens Oliv.
Salacia pallescens Oliv. can be propagated through various methods including seeds, stem cuttings, and suckers.
Propagation through Seeds
The seeds of Salacia pallescens Oliv. can be collected from the mature fruits. After collecting the fruits, the seeds should be removed and cleaned. Then they should be soaked in water for about 24 hours for better germination. The seeds should be sown in well-drained soil mixed with compost. Water the soil regularly but make sure it is not waterlogged. The seeds usually take around 2-3 weeks to germinate.
Propagation through Stem Cuttings
The stem cuttings of Salacia pallescens Oliv. can be taken from the matured and healthy plants. A sharp and clean scissors or knife can be used for taking the cuttings. The cuttings should have at least 2-3 nodes and should be around 6-8 inches long. The leaves of the lower part of the stem should be removed, leaving only a few leaves at the top. Then, the cuttings should be dipped in rooting hormone powder and planted in well-drained soil. The soil should be watered and kept moist but not waterlogged. The cuttings should be kept in a shaded area until they root. The rooting usually takes around 3-4 weeks.
Propagation through Suckers
Suckers are new shoots that grow from the base of the plant. Salacia pallescens Oliv. can be propagated through suckers by separating them from the mother plant with the help of a sharp and clean knife or scissors. The sucker should have some roots and leaves attached to it. The sucker should be planted in well-drained soil and watered regularly until it establishes itself.
