Which potted fruit is the easiest to grow? Toss it in soil and it survives, flowering and fruiting all year round

Today's star
There are quite a few fruit plants that can be grown in pots, such as pomegranate, orange, fig, strawberry and so on. Based on my experience, the easiest potted fruits to grow are, among woody plants, the fig, and among herbaceous plants, this one - the golden fruit. Today I will share with you how to grow golden fruit that actually bears fruit on a balcony.
Golden fruit seedlings
Golden fruit is the customary name we use here; its scientific name is Passiflora, commonly known as "passion fruit", and it is also called egg fruit, vine pomegranate and so on - they are all the same fruit. Before planting, you first need a seedling. I bought mine online, very cheap, 10 yuan for several plants. If a friend nearby grows them, you can ask for a few branches and they will root from cuttings.
With the seedlings ready, the next issue is the potting soil. I used 80% garden soil + 20% black soil (nutrient soil), and the container was a 50cm*35cm styrofoam box. The first time I planted them, I watered thoroughly and placed them in a shady spot. It was summer when I planted them.
3 months, it looks like this
I didn't know until I grew it - golden fruit (passion fruit) is actually so easy to grow. I don't really take care of it normally; I just water when the soil dries out and ignore it the rest of the time. Within a few months, it had already covered the security netting and was growing very lushly. The impatient family members even worried: it has grown so big and still hasn't fruited, maybe it's fake?
Half a year, flowering
Half a year later, the dawn finally came - the golden fruit bloomed, first one flower, then two, then three....... opening gradually. At first I worried: my home is on a high floor, bees can't find it, so how will it pollinate? After checking the information, I found the worry was unnecessary. Golden fruit is hermaphroditic and self-pollinating, no bees needed, so a single plant can bloom and fruit, and there is no need to specially buy two.
Fruiting
Starting one week after flowering, the flowers gradually turned into fruits and slowly grew bigger. I calculated that the first wave produced more than 20 fruits in total, and it was still continuing to flower and continue to fruit. The information says golden fruit (passion fruit) can flower and fruit all year round in South China (my home is in South China), and in northern regions it can also have a half-year flowering and fruiting period, though in northern regions it cannot survive winter outdoors; in winter it must be kept on an enclosed balcony, and with sufficient light it can continue to flower and fruit.
Summary: Golden fruit is a perennial herbaceous vine. Plant it once and it flowers and fruits every year. We usually don't fertilize it much at all; if there are eggshells, chicken feathers, duck feathers and such at home, we just bury them in, and it grows very robustly, not delicate at all, almost able to survive just by being tossed into soil, very easy to grow, and worth having.
