This tree species requires temperatures above 10°C to grow and can tolerate occasional frosts. It is sensitive to cold temperatures, especially below 5°C, which may lead to leaf drop and defoliation that will affect its overall growth and development.
Soil Requirements
Licaria salicifolia prefers well-drained soils that are rich in organic matter, slightly acidic, and fertile. It requires soils that are deep enough to enable its extensive root system to access moisture and nutrients optimally. This tree species has shown a preference for sandy loam soils, though it can tolerate a wide range of soils, including clay soils. Additionally, regular fertilization is essential to ensure maximum tree growth and development.
Cultivation of Licaria salicifolia
Licaria salicifolia can be propagated through seedlings or cuttings. To grow seedlings, plant them in a mixture of sandy soil and organic matter, ensuring they receive enough water and partial shade. Licaria salicifolia grows best in well-draining soil and prefers areas with plenty of light.
It is also important to ensure a spacing of 10-15 feet between Licaria salicifolia plants to promote healthy growth. To facilitate growth, clear the area around the plant of any competing vegetation.
Watering Needs of Licaria salicifolia
Licaria salicifolia requires regular watering during the first year of growth, from the onset of the rainy season until the end of summer. Avoid watering excessively as it can cause waterlogging and root rot. During the second year, you can reduce watering and allow the plant to develop tolerance for drought.
It is advisable to mulch around the trees with organic matter such as leaves, bark chips, or grass cuttings. Mulching will help to conserve water, maintain soil moisture, and control weeds around the plant's base.
Fertilization of Licaria salicifolia
Applying a balanced fertilizer rich in potassium, nitrogen, and phosphorus, every three months, can help to boost the growth of Licaria salicifolia. Fertilize young plants lightly, but mature plants will require slightly more fertilizer.
It is advisable to apply the fertilizer around the tree's base, and it is recommended to use organic fertilizer whenever possible.
Pruning of Licaria salicifolia
Pruning of Licaria salicifolia is not always necessary, but it can help to maintain the plant's shape and control its size. Prune any dead or damaged branches as soon as possible to prevent the plant's energy being diverted to the injury area rather than to essential growth.
Prune the plant during the dry season, and always use clean and sharp pruning tools to avoid infecting the plant with any diseases. Regular pruning also encourages Licaria salicifolia to produce more shoots and branches, promoting dense foliage and healthier growth.
Propagation of Licaria salicifolia (Sw.) Kosterm.
Licaria salicifolia (Sw.) Kosterm., commonly known as "birunga," is a tree species native to the Caribbean and Central and South America. It's a valuable timber tree and has potential as a medicinal and aromatic plant. The following are the methods for propagating Licaria salicifolia.
Seed propagation
Seed propagation is the most commonly used method for propagating Licaria salicifolia. Collect mature fruits that have turned brown or black from the tree and remove the pulp by soaking the fruits in water. Sow the seeds in a nursery at a depth of 2–3 cm in well-drained soil. Keep the soil moist and place the nursery in a shaded area to avoid direct sunlight. The seeds will germinate in approximately 2 - 3 weeks. Seedlings grow well in partial shade, are transplanted after approximately 6 months.
Cuttage Propagation
Cuttage propagation is another method used for propagating Licaria salicifolia. Collect stem cuttings from the tree's semi-hardwood or semi-ripe lateral branches. Cuttings should be approximately 15 - 20 cm long with at least two nodes. Dip the lower end of the cutting in rooting hormone powder and plant it in a container filled with a well-drained propagation medium. Keep the planting medium moist and the container in partial shade. The cuttings take about 6 - 8 weeks to take root. Once rooted, transplant the cuttings into a well-draining soil mix.
Air Layering Propagation
Air layering propagation can be utilized for Licaria salicifolia. The method requires removing a 1-2 cm wide ring of bark from a mature stem and applying rooting hormone to the exposed cambium. Cover the area with moist sphagnum moss and wrap it in plastic wrap that is securely fastened with a rubber band. After roots have formed, remove the plastic wrap and cut the area below the roots, plant it in well-drained soil, and keep it shaded.
These are the propagation methods used for Licaria salicifolia, each with its unique advantages and disadvantages. Proper care must be exercised when selecting a propagation method and follow the propagation methods' proper procedure to ensure the best possible results.
