Botanical Description

Camu Camu is a small, bushy shrub that grows to about 1–3 meters (3–10 feet) in height. The plant has thick, leathery leaves that are glossy and dark green. The flowers of the Camu Camu tree are white to pale pink, and they produce small, round fruits that are about 2–3 cm (0.8–1.2 inches) in diameter.

The fruit is usually bright purple or red when ripe, although it may appear green when unripe. Inside, the fruit contains a high concentration of seeds, and the flesh is bright yellow-orange. The taste is intensely sour, which makes it more suitable for consumption in processed forms like powder or juice, rather than eating raw.

Camu Camu thrives in lowland tropical environments, particularly along the banks of rivers and in areas with high humidity. The plant requires a humid, subtropical to tropical climate to grow well, and it typically flourishes in regions with temperatures between 25–30°C (77–86°F).

Growing Instructions

Camu Camu is native to the Amazon Rainforest and is best suited for regions with tropical and subtropical climates. If you're interested in growing Camu Camu, it’s important to follow specific growing instructions to ensure the plant thrives.

Sunlight: Camu Camu plants require full sun to grow optimally. While the plant can tolerate partial shade, it will produce the most fruit and grow the healthiest when it is exposed to direct sunlight for most of the day. Ensure that the planting site receives at least 6–8 hours of direct sunlight daily.

Soil: The Camu Camu plant prefers well-drained, slightly acidic soil with a pH range of 5.0–6.0. The soil should be rich in organic matter to support healthy root growth. As Camu Camu naturally grows in riverine areas, it also benefits from slightly acidic and moist conditions.

Temperature: Camu Camu thrives in warm, humid environments with temperatures between 25°C and 30°C (77°F–86°F). It does not tolerate frost and requires a consistently warm climate to grow. If growing Camu Camu outside its native range, be sure to replicate tropical conditions, such as in greenhouses or indoor spaces with controlled temperature and humidity.

Watering: This plant requires regular watering, especially in dry periods. Camu Camu prefers a moist environment, but the soil should be well-draining to prevent waterlogging. In areas where rainfall is not sufficient, supplemental watering may be necessary to maintain the plant’s moisture levels.

Spacing: Camu Camu plants should be spaced about 2–3 meters (6–10 feet) apart to allow for their bushy growth and to prevent overcrowding. This spacing ensures that each plant receives sufficient sunlight and air circulation.

Pruning: Pruning Camu Camu plants is essential for maintaining their health and encouraging better fruit production. Prune the plant to remove dead or diseased branches, and trim back excessive growth to encourage better airflow and sunlight penetration. Prune during the dry season to avoid damaging the plant during its growing phase.

Support: Camu Camu plants typically do not require external support, as they grow as bushy shrubs. However, if you live in a particularly windy area, providing some protection or light staking can prevent damage from strong winds.

Life Cycle: Camu Camu grows as a perennial plant, following a typical cycle of germination, vegetative growth, flowering, fruiting, and harvesting.

• Germination: Camu Camu seeds require warm temperatures to germinate. They should be planted in well-draining soil in a warm environment, and germination typically occurs in 2–3 weeks.

• Vegetative Growth: During this stage, the plant develops its roots, stems, and leaves. It may take 1–2 years for the plant to reach maturity and begin flowering.

• Flowering: Camu Camu plants produce white to pink flowers that bloom during the wet season. Pollination is typically carried out by insects or wind, and the plant will start developing fruit shortly after pollination.

• Fruit Set: The fruit begins to form and ripen several months after flowering. The berries turn from green to red or purple as they mature. The harvest season typically occurs from late summer to early fall.

• End of Season: Camu Camu plants enter a dormant phase at the end of the season, shedding some leaves and preparing for the next growing cycle.

Harvesting and Foraging

Harvesting: Camu Camu fruits are usually harvested once they are fully ripe, which can take several months after flowering. The fruit is typically small and round, with a sour taste when fresh. To harvest, gently pick the fruit by hand or use a harvesting tool to avoid damaging the plant.

After harvesting, the fruit is often processed into juice or dried to create Camu Camu powder, which retains most of the nutritional benefits of the fresh fruit.

Foraging: Foraging for wild Camu Camu is possible in areas of the Amazon rainforest, where the plant grows in the wild. However, due to the increasing demand for Camu Camu, many plants are now cultivated in controlled environments to meet the growing market needs. If foraging in the wild, be sure to correctly identify the fruit and follow sustainable harvesting practices.
