When planting walnuts, first in August to September after the mature fruit will be harvested, peeled, and then dried and stored, until the middle of March next year for sowing.
Before sowing, soak the seeds in cold water for 2 to 3 days, then pull them out, mix them into the wet sand, and stack them in the sunny place. The height of the pile is about 30 to 35cm, and then cover them with the wet sand about 10cm thick. Sprinkle water once a day to keep the soil moist. At night, cover them with straw curtain or film to keep them moist and warm. After about 10 to 15 days, the shell will be Dehiscence, wait until the seed is white, and then transplant it into the soil.
