How Cardamom propagates
True Cardamom (Elettaria cardamomum (L.) Maton), is a perennial herbaceous plant belonging to the same family as ginger, native to southern India. It is the most common of the species whose seeds are used as a spice called cardamom.
This plant is widely cultivated in tropical regions and has naturalized in Réunion, Indochina and Costa Rica.
The term Cardamom refers to the spice of the same name that is obtained not only from this plant but also from others of the Zingiberaceae family.
The cultivation of cardamom is difficult outside its natural range as it is a plant that dies with temperatures below 10 degrees and suffers with temperatures between 10 and 15 degrees, while the ideal cultivation temperature is around 22- 25 ° C.
For this reason, outside these areas, the cultivation of cardamom is possible only in pots and, considering that the plant has a high root development and formation of rhizomes, it needs very large pots.
Cardamom is a plant that reproduces by division of the rhizomes. Before moving on to this phase, however, you must make sure that you have prepared a suitable soil to be inserted in the cultivation pot. The substrate must be acidic, with a pH between 5.1 and 5.5 and constantly moistened: therefore, after the division of the part of the rhizomes, to be inserted not very deep, it requires constant and abundant watering, especially in summer.
Within a period of 15-20 days you should see the first shoots emerge, which indicates that the rhizome has released new roots and the plant is growing.
