The bark is gray and rough, while the leaves are simple, alternate, and elliptical in shape, with a smooth texture and dark green color. The plant produces small, greenish-white flowers that grow in clusters, and it bears oblong fruits that are about 4cm in diameter and turn yellow when ripened. The flesh of the fruit is sweet and edible, while the seeds are hard and brown.
Uses
Chrysophyllum ealaense De Wild. has various uses in traditional medicine. The bark and roots of the plant are used to treat various ailments, such as fever, cough, and diarrhea. The fruit is also used to prepare a tonic that is believed to improve immunity and vitality. Additionally, the wood from the tree is highly valued for its durability and resistance to termites and is used to make various household items, such as spoons, bowls, and tool handles.
The plant has not been extensively studied in modern medicine, so its potential benefits and adverse effects are not yet known. However, the tree is endangered due to deforestation and over-harvesting for its valuable wood. Conservation efforts are needed to protect this unique and valuable plant species.
Light Requirements
Chrysophyllum ealaense De Wild. prefers bright indirect light to thrive. It can tolerate some direct sunlight, especially in the morning and late afternoon, but too much direct sunlight can harm the plant. Therefore, it is best to place the plant in a spot where it can receive plenty of bright, indirect light for most of the day.
Temperature Requirements
Chrysophyllum ealaense De Wild. grows best in warm temperatures between 60°F and 80°F (15.5°C to 26.6°C). The plant is sensitive to cold and frost and should be kept away from windows and doors where cold drafts can affect it. Avoid placing the plant in temperature fluctuations and direct heat, such as near radiators or air conditioning vents, which can damage it.
Soil Requirements
Chrysophyllum ealaense De Wild. grows best in a well-draining soil mix with good water retention capabilities. A suitable soil mixture for this plant should contain a blend of peat moss, perlite, and coarse sand. Additionally, the soil should have a slightly acidic to neutral pH and be rich in nutrients such as nitrogen, phosphorus, and potassium. A recommended soil pH for this plant is between 5.5 and 7.0. It is also essential to ensure good drainage to prevent waterlogging, which can cause root rot.
Cultivation of Chrysophyllum ealaense De Wild.
Chrysophyllum ealaense De Wild. can be propagated through seeds obtained from mature fruits. Alternately, the plant can also be propagated vegetatively through stem cuttings.
When planting the seeds or cuttings, select a location that receives plenty of sunlight and has well-draining soil. The plant can thrive in a range of soil types, but it is best to avoid soils that are waterlogged or excessively rocky.
Watering needs
Chrysophyllum ealaense De Wild. prefers slightly moist soil. Water the plant deeply once every week during the growing season and reduce watering during the dormant season or winter months.
Ensure that the soil is not waterlogged and avoid watering the plant during the wet season or periods of heavy rainfall.
Fertilization
Chrysophyllum ealaense De Wild. requires regular fertilization to thrive. Use a balanced fertilizer, applied every three months during the growing season.
The fertilizer should be spread evenly around the base of the plant, ensuring that it does not touch the trunk or stem of the plant.
Pruning
Chrysophyllum ealaense De Wild. requires minimal pruning to promote growth and maintain its shape. Prune dead or damaged branches at any time. However, avoid pruning during the dormant season or winter months.
The plant can be trained into a specific shape by pruning lightly as it grows. However, keep in mind that excessive pruning can reduce the plant's ability to produce flowers and fruit.
Propagation of Chrysophyllum ealaense De Wild.
Chrysophyllum ealaense De Wild. can be propagated through seeds, cuttings, and grafting.
Propagation through seeds
Seeds of Chrysophyllum ealaense De Wild. can be collected from mature fruits. The seeds should be cleaned, dried, and planted immediately or stored in a cool, dry place until planting. They can be planted in well-draining soil that is moist but not waterlogged. Germination usually occurs within 2-4 weeks.
Propagation through cuttings
Chrysophyllum ealaense De Wild. can be propagated through softwood or hardwood cuttings. Softwood cuttings should be taken from new growth in the spring or summer, while hardwood cuttings should be taken from mature wood in the fall or winter. The cuttings should be 6-8 inches long and have at least two nodes. They should be treated with a rooting hormone and planted in a well-draining soil mix. They should be kept moist and in a humid environment until roots have formed, usually 6-8 weeks.
Propagation through grafting
Chrysophyllum ealaense De Wild. can also be propagated through grafting onto a rootstock. This method is usually used for cultivars and to maintain the characteristics of a specific plant. The rootstock should be chosen carefully to be compatible with the scion, and the graft should be kept in a warm, humid environment until it has healed.
Disease and Pest Management for Chrysophyllum ealaense De Wild.
Chrysophyllum ealaense De Wild. is a tropical fruit tree that belongs to the family Sapotaceae. Despite its hardiness, the plant is still susceptible to some diseases and pests. Effective disease and pest management are essential to ensure a healthy and productive tree.
Common Diseases
Fungal diseases are common in Chrysophyllum ealaense De Wild. One of the most common diseases is Anthracnose, caused by the fungus Colletotrichum gloeosporioides. It affects leaves, flowers, and fruits, causing dark, sunken spots. Other fungal diseases include root rot, stem canker, and leaf spot.
Disease Management
To manage fungal diseases, it is essential to keep the tree healthy and not to overwater it. Avoid plant stress and ensure proper soil drainage. Prune dead branches and dispose of them properly. Also, consider using fungicides and follow the manufacturer's instructions.
Common Pests
Chrysophyllum ealaense De Wild. is also susceptible to some pests, including the fruit fly, mealybugs, thrips, and scale insects. Fruit flies are the most common pest. The female lays its eggs under the fruit skin, and the larvae tunnel into the fruit, causing damage and decay.
Pest Management
To manage pests, inspect the tree regularly and pick up fallen fruits to prevent the fruit fly from laying eggs in them. Use pheromone traps to attract and catch fruit flies. Additionally, consider using insecticides designed explicitly for the target pest, following the manufacturer's instructions. Encouraging natural predators can also help manage pests.
