Origin
Erythroxylum coca Lam. var. coca, commonly known as Coca, is native to western South America and is found in Bolivia, Colombia, Peru, and Ecuador. It grows in tropical to subtropical regions, usually at altitudes between 800 and 2,100 meters above sea level.
Common Names
Coca is known by various vernacular names across South America, including "Coca," "Mate de Coca," "Coca Grande," and "Huanuco Coca."
Uses
The leaves of the Coca plant have been used for centuries by indigenous people of the Andes for their medicinal and psychoactive properties. The leaves contain alkaloids, including cocaine, which have stimulant effects on the nervous system and can suppress hunger, thirst, pain, and fatigue. Coca tea is a traditional beverage in South America and is believed to provide energy and relief from altitude sickness.
Despite its potential benefits, Coca has been and continues to be a controversial plant due to its association with the illegal drug trade. The production, sale, and consumption of cocaine, a powerful and highly addictive stimulant derived from Coca leaves, is illegal in most countries worldwide.
General Appearance
The Coca plant is a small, shrub-like tree that typically grows to a height of 2-3 meters. It has simple, alternate leaves that are oval-shaped and dark green, with a glossy, waxy finish. The plant has small, white or yellow flowers that bloom in clusters, and produces small, red berries that contain a single seed. In cultivation, the Coca plant is propagated from seed or cuttings and requires warm, moist conditions to thrive.
Growth Conditions for Erythroxylum coca Lam. var. coca
Erythroxylum coca Lam. var. coca, commonly known as the coca plant, is an evergreen shrub native to the Andean region of South America. It grows best in the mountainous regions of Colombia, Bolivia, and Peru, but can also be found in other parts of the world, such as Indonesia and the Philippines.
Light Requirements
The coca plant requires moderate to bright light in order to grow. It typically grows under the canopies of larger trees in its natural habitat, so it is adapted to thrive in partial shade.

Too much direct sunlight can cause the leaves to scorch, so it is important to monitor the plant's light exposure.
Temperature Requirements
The coca plant grows best in a tropical or subtropical climate with warm temperatures and high humidity. It prefers temperatures between 70-80°F (21-27°C) during the day and 50-60°F (10-15°C) at night. Temperatures below 50°F (10°C) can cause the plant to become dormant, while temperatures above 90°F (32°C) can cause the plant to wilt and die.
Soil Requirements
The coca plant requires well-draining, nutrient-rich soil to grow. It prefers a soil pH between 4.5-6.0, which is slightly acidic. The soil should be kept consistently moist, but not waterlogged. Good drainage is important to prevent root rot. The addition of organic matter, such as compost or manure, can help to improve soil fertility and structure.
Overall, the coca plant is a somewhat finicky plant that requires specific growing conditions in order to thrive. Proper light, temperature, and soil conditions are essential to its growth and success.
Cultivation methods for Erythroxylum coca Lam. var. coca
Erythroxylum coca Lam. var. coca, commonly known as the coca plant, is native to South America and is primarily grown for its leaves, which contain the stimulant cocaine. When cultivating this plant, it is crucial to provide it with a warm and humid environment, as it thrives in such conditions. Therefore, it is best grown in greenhouses or under shade, especially in areas with a cold winter season. The coca plant is sensitive to cold and frost, so it should be cultivated in areas with a minimum temperature of 60°F.
Watering needs for Erythroxylum coca Lam. var. coca
The coca plant requires frequent and ample watering to maintain its health and growth. A well-drained soil mix with good water retention capabilities is ideal for this plant. It is essential to aim for moist soil but avoid overwatering, as this may cause root rot. The best way to know when to water the coca plant is to check the top layer of soil. If it feels dry, it is time to water. Depending on the climate and humidity levels, watering may be required daily or every few days.
Fertilization for Erythroxylum coca Lam. var. coca
Proper fertilization is crucial for the growth and health of the coca plant. It is recommended to use a balanced fertilizer with an N-P-K ratio of 20-20-20 or 16-16-16. Fertilization should be carried out during the growing season, typically from spring to fall, once every two weeks. It is essential to follow the product's instructions and avoid over-fertilization, which can burn the roots and damage the plant.
Pruning for Erythroxylum coca Lam. var. coca
Pruning is an essential aspect of coca plant cultivation, as it helps to promote healthy growth and improve the plant's structure. Pruning should be carried out during the growing season, as this is when the plant is actively growing. It is best to start by removing any dead or diseased leaves or branches. Additionally, pruning should be done to control the plant's height and shape. When pruning, it is essential to use sterilized pruning tools to prevent the spread of diseases between plants. It is recommended to prune no more than 1/3 of the coca plant's foliage at a time.
Propagation of Erythroxylum coca Lam. var. coca
Erythroxylum coca Lam. var. coca is usually propagated by seeds or cuttings.
Propagation by Seeds
The plant produces small, brown, pointed ovoid seeds that have a hard coat. These seeds are generally sown in a prepared nursery bed and are covered with a layer of sand or vermiculite to keep them moist and free from pests. Germination of the seeds usually takes place within 3 to 5 weeks, and the young plants are allowed to grow for a few months before transplanting to the field.
Propagation by Cuttings
Propagation by cuttings is the most common method used in the commercial cultivation of Erythroxylum coca Lam. var. coca. The cuttings are taken from the stem of the plant, and they should be at least 6 inches long. The cuttings are then dipped in rooting hormone and planted in well-drained soil in a nursery bed. The cuttings should be kept moist and sheltered from direct sunlight. After rooting, the young plants are transplanted to the field.
It should be noted that the propagation of Erythroxylum coca Lam. var. coca is a specialized process that requires a lot of expertise and care. It is important to follow the recommended propagation practices to obtain healthy and vigorous plants that will produce high yields.
Disease and Pest Management for Erythroxylum coca Lam. var. coca
Erythroxylum coca Lam. var. coca is a plant species that is commonly found in South America, and is known for being the source of cocaine. As with all living organisms, diseases and pests can affect this plant and may lead to decreased yields, poor quality of produce or even plant death.
