How do you grow passion fruit on a balcony? One paper cup is all it takes for a basketful of harvest

Passion fruit is nutritious and has a sweet-and-sour taste that many people love. Don't throw away the seeds left after eating - keep them and you can grow potted plants on your balcony. How do you grow passion fruit yourself? Let's take a look:
Choosing seeds
From the passion fruit you bought, pick the ripest one or one that has been sitting for a long time, separate out the seeds inside, wash them clean and let them dry. They must be dried, otherwise they easily go moldy. You can also buy ready-made seeds from a flower shop to plant, which is simpler.
Raising seedlings
Find a plastic basin or box, fill it with potting soil, and bury the seeds in the soil - don't bury them too deep. Then wet the soil, cover it with plastic wrap, and put it somewhere with a little indirect light - that's it.
Before planting in soil, the seeds are best soaked for two days, which speeds up germination and makes it easier for them to break through their shells.
Sprouting
After about ten days, they sprout. Once the seedlings grow a little, move them into a disposable cup, being careful not to damage the roots. Poke a few holes in the bottom of the cup to keep the soil aerated. When the seedlings reach about ten centimeters, they can go into a large pot.
If your seedling-raising container is big enough, you don't have to move them out - just move them straight into a flower pot once they grow a bit.
Potting
When the seedlings reach about ten centimeters and have three or four leaves, they can be moved into a flower pot. For potting soil, loose, breathable sandy soil is best: one part garden soil, one part leaf mold, and one part river sand, mixed evenly. When potting, just remove the cup and keep the soil ball, being careful not to damage the young roots. If moving them directly from the seedling tray, also keep a soil ball - you can't just pull them out, as that easily damages the roots.
Choose a large, deep flower pot, because the passion fruit plant is fairly big. No more than two plants per pot, otherwise there won't be enough nutrients and they won't grow well.
Growth management
After potting, put it in a shady spot to recover, and once the plant shows obvious growth, it has survived.
After it survives, put it on the balcony or terrace and give it plenty of light. At noon in summer, shade it so it doesn't get sunburned.
Water moderately, keeping the soil moist, or water when dry and let it dry between waterings - it must not become waterlogged. Make sure there is ventilation, so that even if you water too much, it can evaporate in time. When the roots are comfortable, it will grow healthily and quickly.
For fertilizing, use light fertilizer frequently - two to three times a month with cake fertilizer water, or your own composted fertilizer, both work. Don't make the concentration too high, or you risk burning the roots.
Passion fruit is a climbing vine, so according to its growth needs, build it a trellis or run a string so it can climb smoothly. Passion fruit sends out side branches very quickly, so you can prune appropriately according to your space. Otherwise it will climb like crazy.

Then just sit back at home and wait - charming passion fruit, a whole basketful of harvest.
