Nobody knows exactly where the lemon tree originally came from. An origin from Central Asia, primarily from India and southwest China, is assumed. However, lemons have also been cultivated in the Mediterranean region for many centuries, including cultures during the heyday of the Roman Empire. Since the 16th and 17th centuries, however, the subtropical tree has also been cultivated in Central and Northern Europe, but not in open-air cultivation. Many nobles have created orangeries with the fascinating plants.

Lemon tree needs warmth and lots of light

Unfortunately, despite global warming, it is not yet possible to plant lemons and other citrus fruits in Germany. The continental European climate with its rather short and mostly humid summers and the comparatively long and cold winter period is not suitable for lemons. An exception to this rule is the so-called bitter lemon, also known as the three-leaf orange. The ornamental shrub is frost hardy to about minus 25 °C and the only deciduous citrus species.

Lemon tree ideal for keeping in containers on the terrace or conservatory

However, lemons are not only quite sensitive in winter, they also need appropriate protection in summer. The sensitive plants do not tolerate too much moisture, which is why they have to be placed outside in the warm months, but in a sheltered place at night. A nocturnal summer pitch is ideal

  • near a heat-emitting house wall
  • covered
  • and sheltered from the wind.

It is also better not to leave your lemon outdoors during periods of wet weather or heavy rain. Nevertheless, the lush growing plants love a lot of light and air and should be outside to thrive better. Keeping them indoors is only recommended if the cool winter hibernation can be guaranteed. In order for the lemon tree to remain transportable, it should be planted in a sufficiently large bucket.

With good care, the tree will bear lemons

In contrast to other subtropical or tropical plants, a lemon tree in Germany also develops many fragrant, white to pink flowers and often fruits - provided the care is right. Lemons are relatively high-maintenance, need regular water and fertilizer. The lemons ripen within six to nine months after the start of flowering, but can remain on the tree for a long time even when fully ripe without being damaged. To feel good, lemons need

  • a big enough pot
  • with a water drain on the floor
  • a drainage layer
  • citrus soil
  • a sunny, wind-protected and warm pitch
  • regular fertilizer application
  • not too much water
  • do not use hard water!
  • a cool hibernation

Lemons are quite susceptible to infestation with sucking insects, especially after improper overwintering.

tips and tricks

Don't underestimate the space a lemon needs: the tree will reach a height of two to three meters after just a few years, provided it is not pruned vigorously on a regular basis.
