The tree grows up to 5 meters tall. It has a slender trunk with a diameter of 10-15 cm and a rounded crown. The bark is brownish-gray in color, and the leaves are alternate, elliptical, and shiny. The yellowish-white flowers are small and delicate, and they develop in clusters.
Uses
The wood of Acioa parvifolia has been traditionally used by the local people for fuel, charcoal, and construction purposes. The plant also has medicinal properties and has been used to treat various ailments, including respiratory problems, fever, and diarrhea. The bark extract has shown potential in inhibiting the growth of cancer cells and may have antitumor properties. Acioa parvifolia is also cultivated as an ornamental tree due to its attractive foliage and flowers.
Light Requirements
The plant Acioa parvifolia Engl. requires moderate to bright light for optimal growth. It can tolerate partial shade, but it does best when exposed to full sunlight. In nature, it grows under the canopy of larger trees, which provides filtered light. When grown indoors, it is essential to place the plant near a window where it can receive plenty of sunshine.
Temperature Requirements
The plant Acioa parvifolia Engl. requires warm temperatures throughout the year. It can tolerate lower temperatures, but it may slow down growth during the colder months. The ideal temperature range for this plant is between 20°C to 28°C (68°F to 82°F). It is essential to protect the plant from sudden temperature changes, drafts, and frost, as extreme temperature fluctuations can cause damage to the leaves and stems.
Soil Requirements
The plant Acioa parvifolia Engl. grows best in well-draining soil that is rich in organic matter. The soil should be slightly acidic to neutral, with a pH range of 6.0 to 7.5. The plant prefers moist soil, but it is susceptible to root rot, so it is important not to overwater it. The soil should be allowed to dry slightly between watering, and any excess water in the saucer should be discarded to prevent the plant from sitting in standing water.
Cultivation
Acioa parvifolia Engl., commonly known as the Brazilian cherry, is a tropical plant that requires a warm and humid environment to grow. It can be grown outdoors in USDA hardiness zones 9 to 11 or indoors in a greenhouse or a suitable container. To cultivate Acioa parvifolia, you need well-draining soil, adequate sunlight, and regular watering.
Watering Needs
Acioa parvifolia requires regular watering to maintain soil moisture levels. However, it would help if you were cautious not to overwater the plant as excess water can cause root rot. Water the plant when the top inch of soil feels dry, using a watering can or a hose. Allow the soil to drain before replacing the plant pot on the saucer. You can reduce watering during the winter months when the plant growth slows down.
Fertilization
Fertilization is essential for the growth and development of Acioa parvifolia plants. You can apply a water-soluble balanced fertilizer every two weeks during the growing season. Follow the manufacturer's instructions when applying the fertilizer to avoid over-fertilization. Over-fertilizing can cause fertilizer burn, which can damage the plant and reduce its growth potential.
Pruning
Pruning is essential to keep Acioa parvifolia plants in shape and remove any dead or diseased branches. You can prune the plant during the dormant season, usually between late fall and early spring, to avoid damaging the new growth. To prune, use clean and sharp pruning shears to make a clean cut at a 45-degree angle. Ensure that you do not remove more than one-third of the plant's total foliage to avoid stunting its growth.
Propagation of Acioa parvifolia Engl.
Acioa parvifolia Engl., also known as the Wild cherry tree, is a small evergreen tree that is native to West Africa and can grow up to 15 meters tall. It is quite rare in cultivation, but if you want to grow it in your garden or greenhouse, you can propagate it via:
Seed propagation
The easiest way to propagate Acioa parvifolia is through seeds which can be harvested from the fruit. Choose fresh and healthy fruits with no evident signs of damage or decay. Sow the seeds as soon as possible, as the viability decreases with time. First, scarify the seed coat manually or chemically with a solution of concentrated sulfuric acid. Soak the seeds in tepid water for 24 hours before sowing them in a well-draining potting mix, about 1-2 cm deep. Keep the soil moist and warm, at temperatures between 25-30°C. Seeds take around 1-2 months to germinate, and once the seedlings are large enough, you can transplant them to individual pots.
Cuttings propagation
Acioa parvifolia can also be propagated from cuttings, but it can be more challenging since the tree does not root easily. Take cuttings from mature wood in the early spring before the growing season starts. Use a sharp and sterilized knife to take 15-20cm long cuttings from the shoot tips. Remove the lower leaves and dip the cut end in rooting hormone powder. Place the cutting in a well-draining potting mix or sand, and cover it with a plastic bag to maintain high humidity. Keep the cutting warm and out of direct sunlight. After a few weeks, you should see roots emerging from the base of the cutting. Let the plant grow for a few more weeks before transplanting it to its permanent location.
Disease and Pest Management for Acioa parvifolia Engl.
Acioa parvifolia Engl. is a tropical plant that can be grown in subtropical regions too. However, it can be affected by several diseases and pests that can endanger its growth and fruit production.
Common Diseases
One of the most widespread diseases that can harm Acioa parvifolia Engl. is the leaf spot. This is a fungal infection that can cause brown or black spots on the leaves. To prevent the spread of the disease, it is advisable to remove and destroy the infected leaves and apply a fungicide spray.
Another common disease that affects Acioa parvifolia Englis the powdery mildew. This disease can cause white patches on the leaves, making them look dusty. To manage this disease, it is advisable to remove and destroy the infected parts and apply a fungicide spray.
Common Pests
One of the major pests that cause damage to Acioa parvifolia Engl. is the mealybug. These pests feed on the sap of the plant, weakening it by affecting its growth and productivity. To control mealybugs, one can use a strong jet of water to wash it away, manually remove them or apply neem oil to get rid of them.
Another pest that can invade Acioa parvifolia Engl. is the mites. These tiny pests can cause severe damage by deforming the leaves and sucking the sap out of the plant. One can reduce their population by spraying water frequently to replicate highly humid conditions and/or applying neem oil or insecticide according to the severity of the infestation.
Preventive Measures
Preventive measures are essential to mitigate the risk of diseases and pests affecting the growth of Acioa parvifolia Engl. These measures can include maintaining good sanitation practices, properly pruning of diseased parts, removing weeds that may harbour pests and diseases, and applying pesticides and fungicides periodically.
In conclusion, by following proper hygiene measures, early identification of diseases and pests, and the application of appropriate control measures, the growth and productivity of Acioa parvifolia could be sustained.
