Like to drink coffee and enjoy plants, these two properties linked together, inevitably leads to a coffee plant. The evergreen shrub, which is excellently suited to the culture of the rooms, adorns itself with a sumptuously green leaves dress and even produces flowers and fruits under favorable conditions. The ripe berries invite you for a cozy moment with a cup of delicious coffee.

- Growth height: up to 150 cm
- Foliage: opposite, oblong-elliptic, slightly wavy, smooth margins
- Flowers: white, diameter ca. 2 cm, fünfzählig, sweetish fragrant

plants formIn fact, the coffee plant grows as a shrub whose upright shoots are lignified. The retailer usually sells the species Coffea arabica as a decorative green plant with glossy foliage for the living area. In addition to Arabica coffee, Coffea canephora (Robusta) is one of the most widely cultivated coffee plantations. The plants, which serve the professional production of coffee beans, reach stature heights of 5 m and more. In room and tub culture, the maximum achievable size is significantly lower. To propagate the exotic plants, both the sowing and the rooting of cuttings offers.
LocationCoffea arabica likes it bright and warm. The coffee plant offers a perfect environment:
- a lot of light
- no bright sun (risk of fire damage to the leaves)
- Temperature: 20° - 25° C
- high humidity
- no drafts
- during midsummer like outside (in partial shade)
- October to February a bit cooler (winter rest for regeneration)
- never below 15° C
Tip: Coffee plants grow towards the light. If the grass grows, turn the pot 90°.
Concerning the soil, the coffee plant makes certain demands. If the substrate does not meet their wishes, it will react sensitively. Ideally, the substance enclosing the roots has the following characteristics:
- sufficiently ventilated
- neutral to slightly acidic (pH 5.5 - 6.5)
Tip: In the wild, the coffee plant loves a deep soil. In order to meet her needs during cultivation in our latitude, the planter should not be flat, but relatively high.
to waterCompletely dried out substrate is very likely to be associated with the death of the coffee plant. Therefore, you should always keep the root ball moist to a certain extent. When watering, there are the following criteria to consider:
- lime-free water (eg rainwater)
- no cold water
- Exclude waterlogging
- Allow the upper substrate layer to dry slightly until the next wash
- pour less during the winter rest period
FertilizeIn addition to light, water, heat and humidity, the coffee plant needs nutrients that support its development. Newly purchased or newly transplanted specimens usually initially have sufficient nitrogen, potassium, phosphorus and other minerals. But after about 8 weeks the supply in the substrate runs out. Then commercially available liquid fertilizer provides for replenishment. It is sufficient to fertilize every 14 days according to the instructions for use. During the resting phase, the plant cells work on the back burner, so during this time completely stop the fertilizer.
sowingRoasted coffee beans are not germinable because they have been heated and no longer have moisture. Only by the roasting coffee beans get their characteristic brown color. If you want to grow coffee plants by sowing, you need untreated green coffee beans with a greenish-pale shell.Well sorted seed traders certainly also carry coffee seeds.
Or maybe you know someone who owns a coffee plant that has been seeded. Sowing takes place in low-nutrient potting soil or potting soil mixed with sand. In loose soil, the seeds germinate best, with the sowing at a suitable ambient temperature can take place throughout the year. Proceed as follows:
- Open drupes and take seeds out
- Sprinkle seeds in lukewarm water for several hours
- Fill pots with substrate
- Press seeds into the soil (planting depth approx. 1 cm)
- spray with water or pour gently
- Put the freezer bag over the pot or cover it with cling film
- Germination temperature: 20 - 25° C
- no direct sunlight
- Germination time: 4 to 8 weeks
- keep it evenly moist, but do not overdrain
- Ventilate daily for mold prevention
cuttingsIn addition to sowing, vegetative propagation offers the opportunity to cultivate coffee plants themselves. Maybe someone from the family or circle of friends gives you one or more offshoots. They require head cuttings, that is about 20 cm long, half-lignified tips of a shoot. This is how the rooting succeeds:
- Fill cultivation soil in pots
- in each case remove leaves except for one above pair
- Cuttings with three quarters of their length stuck in soil
- sprinkle and fog the cuttings (lime-free water!)
- provided with transparent hood
- Location: 25° C, bright but no direct sun
- Plant substrate must not dry out
- Air and spray again daily
- after rooting (in 2-3 months) repot
You do not want to sow or pull cuttings? Nurseries, garden centers and various online shops hold for you plants for sale. In this way, you can quickly and easily get to coffee plants. In the specialized trade acquired copies usually have a height of 20 to 30 cm. As a result, they are also quite young. Even with these plants it takes at least 3 years until they flower for the first time. Recognize healthy plants:
- well rooted bales
- compact growth
- strong green foliage
- no brown or ruffled leaves
- free from insects and pests
- moist substrate (not dry and not wet)
blossomsWhen your plant adorns itself for the first time with fragrant flowers, the feeling of happiness will surely go to the limit. Has the long wait time been worth it? The white splendor grows from the leaf axils in short-stemmed inflorescences. Only from fertilized flowers develop seeds. Although Coffea arabica is a pollinator, it does not hurt to help. Take a soft brush and dab the flowers carefully one after the other with his hair.
fruitAfter pollination, the fruiting appear in the form of small, green globules. Over time, the cherries become thicker and change their appearance in a reddish hue. Once they present themselves in a deep red color, they are ready for harvest. The complete maturation process takes about a year. It may be that at the same time both fruits and flowers are on the bush.
Home-produced coffeeOnly a few days and a few simple steps are needed after the harvest to have a leisurely coffee break:
- Remove seeds from the fruit peel
- let it dry in a warm place
- occasionally turn around
- roast the dried beans in the pan for 10 to 20 minutes to the highest level
- Wait 1 to 6 days for the full aroma to unfold
- Grind beans
- Boil coffee powder with boiling water
- Enjoy coffee
What looks like a bush that belongs to purchased specimens are in fact individual plants. Nurseries usually put several saplings in a pot, so that the goods for sale looks fuller and thus appealing. In the beginning, the group likes to stay as it is. But at the latest when the plants compete with each other for space, they are separated.
If then each stalk receives its own pot is at your discretion. It is important that the plants do not hinder each other and all leaves receive enough light. Since after 2-3 years anyway the next repotting occurs, then possibly take place the singulation.During potting there is the possibility to control the roots. You can remove soft or even rotten parts. Provided with fresh earth, the plant claims no fertilization in the following weeks.
Diseases and pestsIf the leaves get brown spots or dry up completely, the cause is usually due to wrong location and growth conditions. Presumably, the plant is too wet or too dry, otherwise too cool temperatures or direct sunlight can lead to damage to the foliage. Pale yellow discoloration is usually a sign of nutrient deficiency. For extremely defaced plants, experts advise a radical cut and then optimal care, so that the coffee plant recovers. Bacterial, viral or fungal diseases are highly unlikely. Only pests cause problems every now and then.
- Scale insects
- rare aphids
pruningIn and of itself, the growth of Coffea arabica is progressing slowly. But over the years, the plant reaches a stately height. Maybe the space allocated to her will eventually be too short. Then you are allowed to reach for the scissors, because coffee plants are very cut friendly. The shortening takes place in the best case in the spring before the new shoot and each over a leaf node. Even with vigorous cuts, the coffee plant gets along well. She reacts with a bushy growth. Severed branches can be used to propagate cuttings.
Tip: Homegrown Coffea arabica sprouts bring a smile to every plant lover.
