How to Take Care of a Coffee Plant: Expert Tips for Thriving Plants and Delicious Beans
How to Take Care of a Coffee Plant?
To take care of a coffee plant, it is important to provide the right growing conditions.
Coffee plants prefer a warm spot with bright, indirect light, such as a conservatory or a well-lit bathroom with high humidity.
The ideal temperature range is 16-24ºC.
Regular watering is necessary to keep the compost moist but not waterlogged, and the plant should be fed with liquid feed every two weeks during the growing season.
To maintain high humidity levels, place the plant in a tray filled with water and pebbles, and regularly mist the leaves.
Repotting should be done every two to three years using loam-based, peat-free compost.
Propagation can be done by soaking seeds overnight and sowing them on moist compost.
Coffee plants can be affected by pests such as the glasshouse red spider mite, but infestations can be prevented or treated with water spraying and biological controls.
Finally, it is important to source coffee plants from reputable nurseries and ensure they are UK-grown to reduce the risk of a bacterium called Xylella fastidiosa, which can cause significant damage to the plant.

Did You Know?
1. The coffee plant, scientifically known as Coffea, actually belongs to the Rubiaceae family, which is the same family as gardenias and quinine-producing plants.
2. Coffee plants are native to the region known as the “coffee belt,” which spans from roughly 25 degrees North to 30 degrees South of the equator. This includes countries like Ethiopia, Brazil, Colombia, and Vietnam, among others.
3. When coffee plants are flowering, they release a sweet, jasmine-like aroma to attract pollinating insects. However, this scent is so subtle that humans can rarely detect it.
4. The coffee plant is technically an evergreen shrub and can grow up to 30 feet tall if left unpruned in ideal conditions. However, for practical purposes, coffee plants are usually kept trimmed at a height of about 6 to 10 feet for easier cultivation.
5. While many people enjoy the aroma of coffee beans, it’s interesting to note that the coffee plant itself does not have a notable scent. The aroma associated with coffee is generated during the roasting and brewing processes.
Coffee Plant Characteristics
Coffee plants, scientifically known as Coffea arabica, have evergreen leaves that are slightly ruffled at the edges, giving them a unique aesthetic appeal. When mature, these plants produce highly fragrant white flowers, which are followed by green fruits that ripen and turn red, then almost black. It is within these fruits that the coveted coffee beans are found, with each fruit containing two seeds. These beans need to be roasted before being ground to unlock their rich, aromatic flavors. It is important to note that while the coffee beans are the prized part of the plant, all other parts, including the leaves and fruits, are toxic to humans and animals.
Growing Conditions For Coffee Plants
To ensure successful growth of a coffee plant, it should be placed in a warm spot out of direct sunlight to mimic its native tropical habitat in Africa and Asia. Ideally, coffee plants should be grown indoors, either as houseplants or in a greenhouse, as they require warm temperatures between 16-24ºC. Provide bright, indirect light to the plant for optimal growth. A great way to maintain high humidity levels, which are beneficial for coffee plants, is to place the plant on a tray filled with water and pebbles, while also regularly misting the leaves. Recommended locations for growing a coffee plant include a conservatory or a well-lit bathroom where these conditions can best be maintained.
Watering And Feeding Coffee Plants
To ensure the health of a coffee plant, regular watering is essential. It is important to keep the compost moist but not waterlogged, as excessive water can lead to root rot. During the growing season, which typically spans from spring to autumn, the plant should be fed with liquid feed every two weeks to supply it with necessary nutrients. This will promote robust growth and guarantee a plentiful harvest of coffee beans. Moreover, to maintain the optimal humidity levels that coffee plants require, regularly misting the leaves and using humidity trays will greatly contribute to their overall well-being.
Propagation And Pruning Of Coffee Plants
Propagation of coffee plants can be achieved by soaking the seeds overnight and then sowing them on the surface of moist compost. Germination can take six to eight weeks, and once the seedlings are big enough to handle, they can be transplanted.
It is important to note that coffee plants can grow to be quite tall, reaching heights of 4-8 meters over a period of five to ten years. To keep them at a manageable size when grown indoors, the plants can be pruned. This should be done in the spring by cutting back the stems at a 45-degree angle just above a leaf joint.
Regular pruning will not only help control the plant’s size but also promote healthier growth.
Dealing With Pests And Diseases
Coffee plants, like many other plants, can be susceptible to pests and diseases. One common pest to watch out for is the glasshouse red spider mite. These tiny mites feed on the sap of the plant, leading to leaf drop and mottled leaves. Identification can be done by looking out for fine webbing on the leaves and stems, as well as mites and eggs on the underside of leaves.
To prevent infestation, spraying the plant with water to increase humidity can be beneficial. If an infestation does occur, biological controls are available to treat the mites effectively.
It is also important to be aware of the bacterium Xylella fastidiosa, which can cause dieback, leaf scorch, and ultimately kill the plant. To reduce the risk of this disease, it is advisable to source coffee plants from reputable nurseries and ensure they are UK-grown, as plants raised in the UK are at a lower risk of Xylella fastidiosa.
Tips for coffee plant care:
- Keep an eye out for signs of infestation such as webbing, mites, and eggs on the underside of leaves.
- Maintain proper humidity levels by spraying the plant with water.
- If infestation occurs, consider using biological controls.
- Purchase coffee plants from reputable nurseries and opt for UK-grown plants to lower the risk of Xylella fastidiosa.
Reducing The Risk Of Xylella Fastidiosa
Xylella fastidiosa is a bacterium that poses a significant threat to coffee plants. To minimize the risk of this disease, several precautions should be taken:
- Acquire coffee plants from reputable nurseries that follow best practices and have a low risk of disease.
- Choose UK-grown coffee plants to further reduce the likelihood of introducing Xylella fastidiosa to your garden.
- Regularly monitor and inspect plants for signs of disease, such as dieback or leaf scorch, to detect any potential issues early on.
By being diligent in sourcing and caring for coffee plants, we can help safeguard these beautiful plants and ensure their continued growth and abundance.
Frequently Asked Questions
How often should I water a coffee plant?
To maintain the health of your coffee plant, it is recommended to water it every 1 to 2 weeks. It is important to allow the potting mix to dry out halfway between waterings as coffee plants do not thrive in consistently wet conditions. The frequency of watering may vary depending on the level of light exposure, with more frequent watering required in brighter light and less frequent watering needed in lower light. Prioritizing these watering guidelines will help keep your coffee plant happy and thriving.
Do coffee plants need high sunlight?
Coffee plants do not require high sunlight as they naturally thrive in understory environments, sheltered under the canopy of forests. They prefer either indirect light or full sunlight in weaker latitudes. Direct, harsh sunlight can actually be detrimental to coffee plants, causing their leaves to turn brown. Therefore, it is best to provide coffee plants with the appropriate level of sunlight to ensure their optimal growth and prevent any leaf browning issues.
How do you keep a coffee plant happy?
To keep a coffee plant happy, it is crucial to maintain proper moisture levels in the soil. Water the plant when the topsoil has dried out, ensuring not to overwater as this can lead to root rot and plant death. In case of waterlogged soil, repotting into well-draining potting soil after trimming off any dead roots can prevent further damage and promote a healthy coffee plant.
Do coffee plants like heat?
Coffee plants generally thrive in moderate temperatures, making them well-suited for upland areas in tropical regions. The Coffea arabica tree, responsible for a significant portion of the world’s coffee production, prefers temperatures within the range of 64°–70°F. These conditions are typically found in upland elevations, where the climate is more moderate and stable. While coffee plants may not necessarily enjoy extreme heat, they tend to flourish in the optimal temperature range for their growth and development.
