The Kaffir lime or Kaffir lime is an evergreen tree with interesting, leathery and quite large, dark green leaves. The rounded, heavily wrinkled fruits contain only a small amount of straw-like pulp. Above all, the very aromatic leaves are used, which - like our laurel - are cooked and give the dishes a fine, citrus-like aroma. Kaffir lime is an indispensable spice, especially in Thai cuisine. In some countries the fruits of the tree are also braised (especially in curries), but not eaten.
How do I properly care for a Kaffir lime?
The care of the Kaffir lime includes a location in full sun, sheltered from the wind, a permeable and slightly acidic substrate, moderate watering with rainwater, regular fertilization during the growing season, annual repotting, overwintering at approx. 10 °C and pruning in spring.
Which location does the Kaffir lime prefer?
The Kaffir lime comes from the tropics and requires a full sun, wind-protected location. It cannot tolerate cold or even frost at all.
What does the substrate have to be like?
The substrate should be permeable - the plant's fine roots cannot tolerate waterlogging - and also slightly acidic. Commercially available lemon soil is best. Ensure proper water drainage by placing a layer of expanded clay at the bottom of the pot.
How much water does the Kaffir lime need?
The water requirement is moderate. The soil in the pot should not be permanently wet, otherwise the roots will rot. It is best to water when the top layer of substrate has dried. The soil should be slightly moist after watering, but not wet. Rainwater is best.
When and with what should the Kaffir lime be fertilized?
Mix special citrus soil into the substrate in spring. Fertilization is repeated regularly throughout the growing season. Pale/light green leaves are an indication of deficiency symptoms.
When do I have to repot my Kaffir lime?
Repot your Kaffir lime every spring and provide it with fresh substrate. Older plants simply need to be moved to a larger pot every two to three years.
Can the Kaffir lime stand on the balcony/terrace?
Yes, absolutely. However, the location must be protected from the wind as the plant cannot tolerate drafts.
How is the Kaffir lime overwintered?
In winter, the Kaffir lime must be brought into the house because it is very sensitive to cold. You should place the tree in a bright room at around 10 °C and water occasionally. However, fertilizing is not necessary in winter.
Does the Kaffir lime have to be cut back?
Yes, it's best to cut the tree back in spring and remove any diseased or dead shoots. Thinning is also necessary so that your Kaffir lime is supplied with sufficient light.
Which diseases/pests are common?
If the air in the room is too dry, spider mites often appear. Otherwise, the Kaffir lime is plagued by the same pests and diseases as the lemon.
Tips & Tricks
The leaves, either cut into fine strips or whole, are an essential component of soups, sauces and various dishes in Thai cuisine. In addition, fresh, dried and candied fruits can be used to make drinks and as a spice, especially their peel. The leaves should be frozen, but not dried.
