Cultivation and harvesting of jicama

Cultivation of jicama is relatively simple, and it can be propagated either by seed or by tubers. Seed propagation requires the selection of robust seeds, which are then buried in the soil, maintained at a suitable humidity and temperature, and transplanted to the field at the right time after germination.

Tuber propagation requires the use of healthy tubers, cut the tubers into medium-sized pieces, and then bury the tubers in the soil to maintain the appropriate humidity and temperature. Tuber propagation is relatively easy to succeed and is suitable for home or small-scale planting.

The growing period of jicama is 6-9 months, and it needs moderate amount of water and sunlight during the growing process. During the growing period, timely weeding, loosening of soil and fertilization are needed to ensure the growth and development of jicama.

The harvesting time of jicama is usually carried out after the tuber grows fully mature. When harvesting, the jicama tubers can be dug out of the soil, cleaned and dried or stored.
