It is also a source of vitamins, minerals, and antioxidants.
The plant is also valued for its ornamental and landscape uses. Its large leaves and unique fruit add a tropical touch to gardens, patios, and public spaces. The wood of Carica candamarcensis Hook. f. is used for making furniture, and its bark and leaves are sources of fiber that can be woven into baskets, mats, and other handicrafts.
Due to its limited distribution and habitat destruction, Carica candamarcensis Hook. f. is considered a vulnerable species by the International Union for Conservation of Nature (IUCN).
Light Requirements
Carica candamarcensis Hook. f. is a plant that requires a lot of light, but not direct sunlight. It is often best to place the plant near a window that faces east or west to ensure it receives bright, indirect light. A lack of proper sunlight can cause the plant to become leggy and develop less fruit.
Temperature Requirements
The ideal temperature range for growing Carica candamarcensis Hook. f. is between 65°F and 85°F (18°C and 29°C). The plant can tolerate slightly cooler temperatures, down to around 50°F (10°C) but may suffer if exposed to frost. Warmer temperatures above 90°F (32°C) can cause the leaves to wilt and dry out.
Soil Requirements
Carica candamarcensis Hook. f. thrives in well-draining soil that is rich in organic matter. A pH range of 6 to 7 is ideal for this plant. It is best to avoid soils that are too sandy or compacted. A good mix of perlite, compost, and peat moss can provide the right growing conditions for the plant.

Propagation of Carica candamarcensis Hook. f.
Propagation of Carica candamarcensis Hook. f. is usually done vegetatively through stem cuttings and air-layering.
Stem cuttings
Stem cuttings are taken from the parent plant and planted in a rooting medium. The cutting should be about 5-8 inches in length and should have at least two nodes. The bottom node is buried in the rooting medium, and the top node is left above the medium. The cuttings should be kept in warm and humid conditions and watered regularly until roots start to form.
Air-layering
Air-layering involves removing a ring of bark from a branch of the parent plant, covering the wound with a rooting hormone and moist sphagnum moss, and then wrapping it in a plastic bag. Roots will emerge from the wound and grow into the moist moss. The rooted branch can then be cut from the parent plant and planted in a potting mix.
Both methods of propagation have been successful for Carica candamarcensis Hook. f. However, stem cuttings have been reported to have a higher success rate than air-layering.
Disease and Pest Management for Carica candamarcensis Hook. f.
Carica candamarcensis Hook. f. is a plant species that is native to South America and is commonly known as the Andean papaya or mountain papaya. It is mainly grown for its delicious and nutritious fruit that is rich in vitamins and minerals. However, like any other plant species, Carica candamarcensis Hook. f. is susceptible to various diseases and pests that can affect its growth, yield, and quality. Therefore, disease and pest management are essential for the successful cultivation of this plant. Here are some common diseases and pests that might affect Carica candamarcensis Hook. f. and ways to manage them.
Common Diseases
Anthracnose is a fungal disease that affects the foliage, flowers, and fruits of Carica candamarcensis Hook. f. The infected parts develop brownish spots that gradually enlarge and become sunken, leading to premature fruit drop. To manage anthracnose, avoid overhead irrigation, remove and destroy infected plant parts, and apply fungicides such as copper-based products.
Papaya Ringspot Virus (PRSV) is a viral disease that causes mottled leaves, stunted growth, and reduced fruit quality and yield. The virus is transmitted by aphids and infected seeds. To manage PRSV, use virus-free seeds, control aphid populations, and remove and destroy infected plants.
Powdery Mildew is a fungal disease that affects the leaves, stems, and fruits of Carica candamarcensis Hook. f. The infected parts develop a powdery white coating that leads to reduced photosynthesis, stunted growth, and defoliation. To manage powdery mildew, improve air circulation around the plants, avoid overhead irrigation, remove and destroy infected plant parts, and apply fungicides such as sulfur-based products.
Common Pests
Papaya Fruit Fly is a pest that attacks the fruits of Carica candamarcensis Hook. f. The female fruit fly lays eggs on the surface of the fruit, and the hatched larvae tunnel into the flesh, causing the fruit to rot and drop prematurely. To manage papaya fruit fly, use yellow sticky traps, avoid using ripe or damaged fruits as bait, and apply insecticides such as pyrethroid-based products.
Mealybugs are pests that suck sap from the leaves, stems, and fruits of Carica candamarcensis Hook. f. The infested parts develop a sticky honeydew secretion that attracts ants and promotes the growth of sooty mold. To manage mealybugs, use biological control agents such as ladybugs and lacewings, remove and destroy heavily infested plant parts, and apply insecticides such as neonicotinoid-based products.
Spider Mites are pests that feed on the underside of the leaves of Carica candamarcensis Hook. f. The infested leaves develop yellowish or reddish spots that eventually turn brown and fall off, leading to defoliation and reduced yield. To manage spider mites, improve air circulation around the plants, avoid overhead irrigation, use biological control agents such as predatory mites and spiders, and apply acaricides such as abamectin-based products.
In conclusion, Carica candamarcensis Hook. f. is a plant species that requires proper disease and pest management for optimal growth and yield. By following the above suggestions, farmers can grow healthy and productive Andean papayas that are of high quality and marketability.
