Growing the plant indoors is not recommended as it requires natural sunlight to thrive, but if grown indoors, place the plant near a sunny window or use artificial grow lights.
Temperature Requirements
The Malpighia crassifolia L. plant can tolerate a wide range of temperatures, but optimal growth conditions are within 70°F to 90°F (21°C to 32°C). Temperatures below 50°F (10°C) or above 100°F (38°C) can harm the plant, and it may not survive. Therefore, it is essential to grow the plant in a temperature-controlled environment or select a planting location that suits its preferred temperature range.
Soil Requirements
The Malpighia crassifolia L. plant requires a well-draining soil mixture. The soil should be rich in organic matter and slightly acidic, with a pH range of 5.5 to 6.5. A mixture of peat moss, perlite, and coarse sand is an ideal choice for the soil mixture. The plant also benefits from regular fertilization every four to eight weeks, using a balanced fertilizer specially formulated for acid-loving plants.
Cultivation methods
Malpighia crassifolia L., commonly known as the Acerola or West Indian cherry, is a small tree that grows best in subtropical and tropical climates. It can be cultivated in both pots and the ground, though it prefers well-drained soil with a pH between 5.5 and 7.5. It requires full sun and protection from strong winds.
Watering needs
Acerola trees require regular watering, especially during the growing season, to keep the soil moist, but not waterlogged. Generally, a weekly deep watering is sufficient, providing approximately one inch of water. During winter dormancy, watering can be reduced to every other week, adjusting according to weather conditions, and checking the soil regularly.
Fertilization
Acerola trees are heavy feeders and benefit from regular fertilization. A balanced fertilizer, such as a 10-10-10, should be applied every three months during the growing season. Organic fertilizers such as compost and fish emulsion can also be used. It is important not to over-fertilize, as this can lead to excessive growth and poor fruit quality.
Pruning
Pruning Acerola trees is necessary to develop a strong structure and to remove damaged or diseased branches. It is best to prune during the winter dormancy period, as this can help stimulate new growth. To promote fruit production, pruning should encourage a branching habit that increases access to sunlight and air circulation in the canopy. Any suckers that appear around the base of the tree should also be removed as soon as possible.
Propagation Methods of Malpighia Crassifolia L.
Malpighia crassifolia L. or commonly known as Acerola, is a perennial evergreen shrub that is widely known for its edible fruits that are high in Vitamin C content. It is a tropical plant that is native to the West Indies, but it also grows in other tropical regions of the world. Propagation of Acerola can be done through several methods such as seeds, cuttings, and grafting.
Seed Propagation
The propagation of Acerola through seeds is the simplest method as it does not require much effort. However, it is essential to note that seed propagation does not always produce plants that are identical to the parent plant. To propagate Acerola from seeds, the following steps should be followed:
- Collect ripe fruits and remove the flesh of the fruit to expose the seeds.
- Clean the seeds, removing any sticky covering and let them dry for a few days.
- Sow the seeds in a seed tray or a pot with well-draining soil and cover them with a thin layer of soil.
- Water the seeds lightly and keep them in a warm and humid place to germinate.
- The seeds will germinate within 1-2 weeks, and once the seedlings have grown two sets of leaves, they can be transplanted.
Cutting Propagation
The cutting propagation method is an excellent way to propagate identical clones of the parent plant. To propagate Acerola from cuttings, the following steps should be followed:
- Take a healthy branch of the Acerola plant that is about 10-15 cm long with a few leaves.
- Remove the leaves from the bottom half of the cutting and make a clean cut at the bottom of the stem.
- Dip the bottom of the stem in rooting hormone powder and plant it in a pot with well-draining soil.
- Water the cutting and keep it in a warm and humid place, out of direct sunlight.
- After a few weeks, roots will start to develop, and new leaves will start to grow.
- Once the new plant has grown two sets of leaves, it can be transplanted to a larger pot or the ground.
Grafting Propagation
Grafting is a method that is commonly used to propagate Acerola as it ensures that the new plant has the same characteristics as the parent plant. To propagate Acerola through grafting, the following steps should be followed:
- Select a healthy Acerola plant that will serve as the rootstock and a similar healthy plant that will serve as the scion.
- Cut a branch from the rootstock plant and cut off the top to leave a flat surface.
- Cut a branch from the scion plant, remove the leaves, and make a slanting cut.
- Place the scion on the flat surface of the rootstock and wrap them together tightly with grafting tape.
- Water the plant and keep it in a warm and humid place until the graft takes.
- Once the graft has taken and the new growth is visible, remove the grafting tape.
- When the new plant has grown two sets of leaves, it can be transplanted to a larger pot or the ground.
Overall, Acerola propagation can be done using various methods, and the choice of method will depend on the availability of resources and expertise.
Disease and Pest Management for Malpighia Crassifolia L.
Malpighia crassifolia L or acerola is susceptible to various diseases and pests that could threaten its growth and productivity. It is crucial to identify these problems early and manage them effectively to ensure a healthy plant. Here are some common diseases and pests that could affect the plant and their respective management techniques:
Diseases
Bacterial spot: This disease is caused by the Xanthomonas campestris pv. pruni bacteria, leading to purple or black spots on the leaves. It is common in warm and humid conditions and spreads through infected plant tissue or windblown rainwater. To manage this disease, remove infected leaves and branches immediately and apply a copper-based fungicide.
Powdery mildew: Powdery mildew is a fungal disease that creates a white, powdery substance on the leaves, causing them to wilt and die. It spreads via airborne spores and high humidity. Minimize overhead watering and apply a fungicide with neem oil or sulfur on the plant to control the spread of powdery mildew.
Gloeosporium spot: Gloeosporium spot is a fungal disease identified by brown spots on the plant's leaves. It develops in warm and humid climates and spreads through splashing water. To manage this disease, prune infected parts of the plant and apply a fungicide spray containing copper.
Pests
Spider mites: Spider mites are tiny arachnids that feed on the plant's sap creating a yellow, speckled appearance on the leaves. They prefer hot and dry conditions, and their populations increase drastically from spring to summer. To control them, remove any affected leaves and apply an insecticidal soap, neem oil, or a miticide if necessary.
Aphids: Aphids are small insects that feed on the plant's sap, leading to curled and distorted leaves. They prefer cooler temperatures but can survive in warm conditions as well. To manage these pests, apply insecticidal soap or neem oil to the plants, prune any infected portions, and encourage beneficial insects' presence, such as ladybugs.
Fruit flies: Fruit flies are common pests and feed on the ripe berries, causing them to rot prematurely. To manage fruit flies, use yellow sticky traps, place a mesh screen, or cover the fruit until harvest. Additionally, follow good sanitation protocols to eliminate any potential breeding sites.
These are some of the few common diseases and pests that could affect Malpighia crassifolia L. Close monitoring and early intervention are critical in ensuring a healthy and productive plant. Regular pruning, good sanitation protocols, and the use of approved insecticides and fungicides can go a long way in protecting the plant from potential threats.
