Even if the coffee plant is in principle quite easy to care for, it reacts to the wrong location or care mistakes with a discoloration of the leaves. If they turn brown or yellow, you should react quickly.
Brown spots can have very different causes
A few brown spots on the leaves of your coffee plant can simply be sunburn. A young coffee plant does not tolerate direct sunlight that well, an older one should at least get used to it slowly. An infestation with pests can also show up as individual spots. You should fight them immediately.
Scale insects in particular like to appear on the coffee plant. If the infestation is small, try home remedies. A heavy infestation can often only be combated effectively with appropriate chemicals.
What's behind brown leaves?
If whole leaves turn brown, your coffee plant could have gotten a draught, for example, or it could have had too little light. In this case, you should change the location immediately. Your coffee plant likes it warm and light, without wind or draughts. Even in winter it must not be too cold, it needs at least 15 °C.
If you water your coffee plant too much or too little, it may also react with discoloration of the leaves, as well as too much or too little fertilizer. Here you should definitely adjust the care. If the soil is relatively wet, it is best to replace it immediately.
When you repot your coffee plant, check the roots. Remove any rotten or soft parts. Then put the plant in fresh soil. Water the coffee plant carefully. In the next few weeks, water a little more sparingly than before and refrain from fertilizing.
Possible causes of brown spots or leaves:
- sunburn
- too little light
- too low humidity
- possibly a draft
- watered or fertilized incorrectly
- possible pest infestation
tips
A change of location is usually recommended as the first remedial measure. If this does not help, then you should reconsider the previous care.
