Soak Yambean (Jicama) seeds with clean water (room temperature, 20-26 C) for 9 hours. Water for immersion should be bottled water or boiled water. At the end of the immersion, if any seeds are still floating, throw them away. Take the seeds using a sieve and wash with clean water (boiled water). Drain / release (leave it open until it dries on its own).
Prepare a seeding container. The underside must be given enough holes for water circulation. The day before the seedlings, fill with 3/4 of the seedlings. Seedling media composition = soil : sand/husk : compost = 1 : 1 : 1. Insert Yambean (Jicama) seeds into seedling media with depth of 0.7 – 1.2 cm. Spray fine water 1-2 times a day if the media is dry.
Prepare a Polybag. Polybag/pot must be given a hole in the bottom. The day before planting, fill in polybag/pot with up to 3/4 growing media. The composition of the planting media = soil : sand/husk : compost = 2 : 1 : 1. Take the seeds and soil around the roots. Enter into the hole in an upright position, add soil around it. Put polybag/pot in the shade. After new leaves grow, place polybag/pot in a bright place. Take care of the Yambean (Jicama) plant.
