It grows in a variety of soils, from well-drained to poor and acidic soils.
Common Names
Passiflora tripartita var. mollissima is known by many common names, including banana passionfruit, sweet granadilla, curuba de guayaquil, and tacso. In different regions, it is known by different names, but all refer to the same plant with edible fruit.
Uses
Passiflora tripartita var. mollissima is mainly cultivated for its fruit, which is sweet and tangy, with a juicy pulp and black seeds. The fruit is rich in vitamin C, fiber, and antioxidants. It is eaten fresh, juiced, canned, or used to make desserts, jams, and beverages. The leaves and stems of the plant are used in traditional medicine to treat anxiety, insomnia, and respiratory problems. The plant is also used as an ornamental vine for its unique flowers and textured leaves.
General Appearance
Passiflora tripartita var. mollissima is a vigorous, woody vine that can grow up to 6 meters long. It has dark green leaves that are deeply lobed and covered with fine hairs. The flowers are large, showy, and purple-white, with a unique central structure called the coronal filaments. The fruit is oval-shaped and up to 10 centimeters long, with a green or yellow skin that turns brownish when ripe.
Light requirements
Passiflora tripartita var. mollissima requires full sunlight for optimal growth. It can tolerate some shade, but excessive shade may hinder its growth and flowering abilities.
Temperature requirements
The plant prefers a warm and humid climate. It grows best in temperatures between 20°C to 30°C (68°F to 86°F) during the day and 15°C to 20°C (59°F to 68°F) at night. It cannot tolerate frost or temperatures below 10°C (50°F). Extreme heat and dry conditions may also be detrimental to its growth.
Soil requirements
Passiflora tripartita var. mollissima grows well in well-draining soils with a pH range of 4.5 to 6.5. It prefers soils that are rich in organic matter and nutrients such as nitrogen, phosphorus, and potassium. The plant can survive in nutrient-poor soils but may not thrive and may produce smaller fruits. The soil should also be kept moist but not water-logged to prevent root rot.
Cultivation Methods
Passiflora tripartita (Juss.) Poir. var. mollissima (Kunth) Holm-Niels. & P.Jørg. is a subtropical plant that requires a warm and humid environment. It prefers a well-drained soil with a pH range of 6.0 to 7.5. The plant requires plenty of sunlight but doesn't thrive in direct sunlight. It is recommended to grow this plant in partial shade, especially during the hot summer months. The plant is generally propagated by seeds sown in well-draining soil during spring.Watering Needs
The plant requires moderate watering, and it should be kept moist but not waterlogged. Watering should be reduced during winter to prevent root rot. Overwatering can lead to yellowing and dropping of leaves, and under watering can result in wilting.Fertilization
Passiflora tripartita (Juss.) Poir. var. mollissima (Kunth) Holm-Niels. & P.Jørg. requires regular fertilization to promote healthy growth. It is recommended to feed the plant with a balanced fertilizer every two weeks during the growing season. Fertilizers containing high levels of nitrogen should be avoided since excessive nitrogen leads to poor fruit production.Pruning
The plant requires regular pruning to prevent it from becoming overgrown. Pruning is typically done during winter and early spring. It is important to remove dead or diseased wood to prevent the spread of infections. In addition, the plant produces fruit on new growth, so pruning helps to encourage fruit production. It is recommended to cut back old woody stems to promote new growth.Propagation of Passiflora tripartita var. mollissima
Passiflora tripartita var. mollissima, also known as banana passionfruit, can be propagated through several methods. The plant is commonly propagated through seed germination, cuttings, and layering. The following are the details of each propagation method:
Seed Germination
Passiflora tripartita var. mollissima seeds can be germinated in a well-draining soil mix or a peat pot. The seeds should be placed 1/4 inch deep in the soil mix and kept moist but not soaking wet. The ideal temperature for seed germination is between 70-75°F (21-24°C). Germination should occur within 2-4 weeks.
Cuttings
Passiflora tripartita var. mollissima can also be propagated through stem cuttings. The stem cuttings should be taken from mature, healthy plants in the spring or summer. The cuttings should be approximately 6-8 inches long and have at least two to three nodes. The cuttings should then be dipped in rooting hormone and planted in a well-draining soil mix. It is important to keep the soil moist and the cutting in a warm, humid environment. Rooting should occur within 2-3 weeks.
Layering
Layering involves rooting a stem that is still attached to the parent plant. To propagate passiflora tripartita var. mollissima through layering, select a healthy, flexible stem close to the ground. Gently remove the leaves from the area where the stem will be making contact with the soil. The stem should then be lightly wounded and covered with soil, leaving the growing tip exposed. The stem should be held down with a stake or clip and kept moist. After a few weeks, roots should start to grow, and the new plant can be separated from the parent plant and carefully transplanted.
Disease management
Passiflora tripartita var. mollissima is prone to various fungal diseases, including fusarium wilt, powdery mildew, black spot, and anthracnose. These diseases can cause stunted growth, wilting, leaf spots, and fruit rot, among other symptoms. To manage these diseases effectively, it is advisable to take a preventive approach by practicing good cultural practices, including:
- Planting disease-free seedlings or cuttings
- Sterilizing tools to prevent the spread of pathogens
- Keeping the planting area clean and free of debris
- Managing moisture levels to avoid creating a favorable environment for pathogens to thrive
- Applying fungicides as a last resort
If you notice any signs of disease on your Passiflora tripartita var. mollissima plants, it is essential to act promptly. Remove and destroy infected plant parts, and apply an appropriate fungicide to protect healthy plant parts.
Pest management
Passiflora tripartita var. mollissima is also vulnerable to various pests, including aphids, spider mites, scale insects, and whiteflies. These pests can weaken plants, reduce yields, and transmit diseases, among other issues. To manage pests in your Passiflora tripartita var. mollissima crop, consider the following practices:
- Regularly inspecting plants for signs of pests
- Removing and destroying infested plant parts immediately
- Encouraging beneficial insects, such as ladybugs and lacewings, that prey on pests
- Applying insecticidal soap or neem oil to control minor pest infestations
- Using chemical pesticides only as a last resort and following label instructions carefully
With proper pest management practices, you can reduce pest populations, improve plant health, and increase yields in your Passiflora tripartita var. mollissima crop.
