Select a disease-free, large and good color passion fruit, put it in a ventilated place and let it stand for a period of time. When it is fully mature, take out the seeds, take them out and wash them for use.
Soak the seeds in clear water for a day and a night, so as to improve the germination rate. After soaking, spread the seeds on the wet paper towel, then put the paper towel in a transparent plastic box, and seal it with plastic film.
When the seeds show a white tip, they can be seeded directly on the prepared soil surface, and then covered with a layer of fine sand and watered in time.
Soon after planting, we can see the dense seedlings growing. At this time, we need to carry out seedling thinning, not to let them all squeeze together, which will affect the growth of individuals. After seedling thinning, there is a certain gap between the seedlings, so that they can absorb nutrition and air circulation.
