Cinchona pubescens, also known as red cinchona and quina (Kina) ((in Spanish) Cascarilla, cinchona; (in Portuguese) quina-do-amazonas, quineira), is native to Central and South America. It is known as a medicinal plant for its bark's high quinine content- and has similar uses to Cinchona officinalis in the production of quinine, most famously used for treatment of malaria.
Quinine is highly disease-resistant and is typically not susceptible to illnesses. Regarding care, this plant is fairly low maintenance. When grown outdoors it needs only light watering, and larger specimens usually do not require pruning. Smaller specimens, however, should be trimmed after they finish blooming. Quininet is well suited to anyone with an outdoor area, such as a garden or deck, and does not demand much care experience.
How to keep Cinchona Pubescens.
Light
Quinine comes from open habitats, like sunlit meadows and forest margins, where light is abundant. It performs best in full sun but can also withstand partial sun, adjusting well to different sunlight levels.
Water
Quinine, which originates from the Andes, thrives under conditions of periodic heavy rainfall followed by dry spells. It grows best in well-drained soil and can tolerate moderate drought. To mimic its natural cycle, water the plant every 2-3 weeks, and reduce watering during its dormancy period in cooler climates.
Humidity
This plant needs special care because it loves high humidity levels of 60-80% or more. The best way to achieve this is by placing a humidifier near the plant. Daily misting is also essential! Make sure the room has good ventilation.
Temperature
Quinine comes from tropical areas, which are usually warm and humid. Because of this, it is adapted to high heat and humidity. It does not tolerate abrupt temperature shifts and prefers a steady thermal environment, so avoiding indoor temperature fluctuations is important. It generally cannot endure cold and needs warmer conditions to grow. If the temperature falls too low, the plant may stop growing or even die.
Fertilizer
The best time to fertilize a Quinine is in early spring as it comes out of dormancy. This stimulates overall growth and flower development. Fertilization improves the foliage, stems, and branches, and encourages flowers that are large, vibrant, and long-lasting. It helps transport nutrients from the roots to the flowers and enhances the plant’s health and disease resistance.
Pruning
Quinine is prized for its medicinal properties. To maintain its health and vitality, it is best to prune it from early to late winter. Concentrate on removing dead or overgrown branches with sharp, sterilized tools. This practice enhances airflow and light penetration, leading to a fuller appearance and improved overall vitality.

Reader questions.
What are the sunlight requirements for Quinine plants?
Quinine plants originate from environments that offer ample light such as sunny meadows and forest edges. They thrive best in full sun, needing above 6 hours of sunlight daily, but can also adapt well to partial sun conditions, requiring about 3 to 6 hours of sunlight. Selecting the ideal spot in your garden requires careful observation throughout the day to ensure a perfect balance of light and shade, which is essential for the plant's health and growth.
How can artificial lighting supplement natural sunlight for Quinine plants indoors?
When natural sunlight is insufficient, especially during winter or in less sunny indoor spaces, artificial lighting becomes an essential solution for Quinine plants. LED lights are recommended due to their ability to be customized to provide specific wavelengths required by the plants. Full sun plants need 30-50W/sq ft, partial sun plants 20-30W/sq ft, and full shade plants 10-20W/sq ft of artificial light. The light source should be placed 12-36 inches above the plants to mimic natural sunlight, ensuring they receive 8-12 hours of light per day.
What are the common symptoms of light deficiency in Quinine plants?
Quinine plants exhibit several symptoms when they suffer from light deficiency, including smaller new leaves, leggy or sparse growth, accelerated leaf drop, delayed or halted growth, lighter-colored new leaves, chlorosis (leaves turning yellow), sunscald, leaf curling, wilting, and leaf scorching. These signs indicate the plant is not receiving adequate sunlight, affecting its health and ability to grow properly.
How can I address and prevent light deficiency in Quinine plants?
To prevent light deficiency in Quinine plants, gradually move them to sunnier locations to ensure they receive at least 6 hours of direct sunlight daily. Indoor plants may benefit from artificial lighting if moving them is not feasible. Place a desk or ceiling lamp on for at least 8 hours a day or consider professional grow lights. Outdoor and ground-planted Quinines should be moved with care to avoid sunburn, by pruning obstructive trees or transplanting them to sunnier spots with ample light and good drainage. Note that parts of the plant already affected by insufficient light may not recover, but new growth should be healthy after adjusting light exposure.
