The lemon (Citrus limon) originally comes from the subtropical to tropical climate zones of South Asia and has been cultivated for many thousands of years, especially in India and China. The tree reached the Mediterranean region around 1000 years ago through Arab traders and could also become native there.
Sun, sun and more sun
Due to this origin, it is not at all surprising that a lemon tree basically cannot have enough sun. During the vegetation period, the plant needs full sun, preferably protected from rain and wind - preferably outdoors. Even in a very bright place in the apartment, it can still be too dark for the little tree, because here the light is heavily filtered through the mostly double-glazed window panes. What appears bright to people means dark night for a lemon tree and it will react to this by throwing up leaves. In winter, on the other hand, the lemon needs a bright but cool location with temperatures between five and a maximum of 10 °C.
tips and tricks
When wintering a lemon tree, remember that the warmer the ambient temperature, the brighter it needs to be. If you spend the winter in a heated living room, you should definitely install a plant lamp (€21.99).
