Coffee Plant Care Guide
Background
Coffee plants are flowering plants native to tropical regions of Africa, Asia, and Central and South America. They are grown for their seeds, which are roasted and ground to produce coffee. Coffee plants belong to the genus Coffea and the family Rubiaceae. They are small trees or shrubs that would be a great addition to your backyard. This coffee plant care guide will walk you through all the tips and tricks of growing coffee!
Sunlight
Coffee plants need at least 6-8 hours of direct sunlight per day in order to thrive. However, it is important to note that too much direct sunlight can be harmful to the plants, as it can cause the leaves to burn. It is recommended to provide some shade for the plants during the hottest parts of the day to protect them from excessive sunlight.

Humidity
Coffee plants require a humid environment in order to grow and produce fruit. They are native to tropical regions, where the humidity is generally high, and they typically require humidity levels of around 60-70% in order to thrive. If the air is too dry, the plants may suffer from drought stress, which can result in reduced growth and fruit production. In areas with low humidity, it may be necessary to use a humidifier or mist the plants regularly to maintain the proper humidity levels.
Temperature
Coffee plants thrive best in a warm, tropical climate in order to grow and produce fruit. They prefer temperatures between 15-24°C (60-75°F) and are sensitive to cold temperatures. If the temperature drops below 10°C (50°F), the plants may be damaged or killed. Coffee plants also need a certain amount of temperature variation between day and night in order to flower and produce fruit. In general, coffee plants prefer a diurnal temperature range of around 10-15°C (50-59°F).
Watering
Coffee plants require regular watering in order to grow and produce fruit. The frequency of watering will depend on the soil type, temperature, humidity, and other factors. In general, coffee plants should be watered deeply and consistently, allowing the soil to dry out slightly between waterings. Overwatering can lead to root rot and other problems, while under watering can cause the plants to become stressed and reduce fruit production. It is important to monitor the soil moisture and adjust the watering schedule as needed to ensure that the plants receive the right amount of water.
Best Soil for Coffee Plants
Coffee plants prefer well-draining soil that is rich in organic matter, peat moss, sphagnum moss, and vermiculite. They do not tolerate waterlogged soil, as this can lead to root rot and other problems. In general, coffee plants prefer a soil pH between 6.0-6.5, although they can tolerate slightly acidic or alkaline soils. The soil should also be well-aerated, as coffee plants require oxygen to their roots in order to grow and thrive. In addition to these requirements, coffee plants also benefit from the addition of compost or other organic matter to the soil to provide additional nutrients.
Susceptible Pests & Diseases
There are many diseases and pests that can affect coffee plants, including:
Diseases:
Coffee rust
Coffee berry disease
Leaf blight
Pests:
Coffee leaf miner
Coffee borer
It is important to monitor coffee plants for signs of disease and pests and take steps to control them if necessary to protect the health and productivity of the plants. This may involve using pesticides, applying organic controls, or implementing cultural practices such as proper watering and pruning.
Propagation
There are several methods for propagating coffee plants, including seed, stem cuttings, and air layering. Here are four basic steps for propagating coffee plants using stem cuttings:
Choose a healthy, mature coffee plant as the source for your cuttings. The best time to take cuttings is during the active growing season, usually in the spring or summer.
Select a stem that is at least 10 cm long and has several healthy leaves. Make a clean cut just below a leaf node, using a sharp knife or pruning shears.
Remove the lower leaves from the cutting, leaving only the top leaves. Dip the cut end of the stem cutting into a rooting hormone to encourage root development.
Plant the stem cutting in a well-draining soil mix, water well, and place in a warm, humid location. Keep the soil moist, but not waterlogged, and provide indirect sunlight until the cutting has rooted and starts to grow new leaves.
It may take several weeks or months for the stem cutting to root and begin to grow. Once the cutting is well-established, it can be transplanted into a larger pot or into the ground.
Frequently Asked Questions
-
According to the ASPCA, coffee plants are toxic to cats, dogs, and horses. If ingestion occurs it may cause dermatitis, nausea, vomiting, anorexia, and much more. If you believe your pet has consumed something contact a vet or medical provider immediately.
-
Yes, coffee beans can be planted to grow coffee plants, but they need to be germinated first in order to sprout.
-
Coffee plants can often be purchased at nurseries or specialty plant stores, or they can be ordered online from a variety of retailers.
-
Coffee grounds can be a good source of nutrients for plants, as they contain small amounts of nitrogen, potassium, and other minerals. However, it is important to use coffee grounds in moderation, as they can also contain compounds that can be harmful to plants in high concentrations. In general, it is best to mix coffee grounds with other types of compost or add them to the soil in small amounts to provide a balanced source of nutrients for plants.
