Thought to have originated in the foothills of the Himalayas (i.e. Myanmar, North India, South West China), the lemon tree is now cultivated worldwide and in subtropical and Mediterranean climates. The subtropical tree flowers and bears fruit all year round in good conditions and can grow up to six meters high.
Lemons do not tolerate strong temperature fluctuations
As a subtropical plant, the lemon tree tolerates light frosts down to about minus 4 °C, but is sensitive to strong temperature fluctuations. In addition, the lemon - like all citrus plants - needs a lot of water and regular fertilizer to be able to grow well. However, the location is particularly important: lemons love the sun. During the growing season, a sunny and sheltered place outdoors would be best. In principle, it is also possible to keep them indoors, but indoor lemons usually do not grow so luxuriantly. However, lemons can sprout quickly and grow very large, especially in very bright conservatories and greenhouses. Regular pruning stimulates growth.
tips and tricks
Homegrown lemons need at least eight to twelve years before they eventually bear flowers and fruit. In order to shorten the long period of youth, you should graft the one-year-old tree.
