Choose these 5 vegetables for balcony gardening: easy to grow and care for, plant once and harvest for a whole year

If your balcony is a bit larger, with good light and good ventilation, you might as well grow a few pots of green vegetables yourself. Autumn is a great time for planting vegetables. Some vegetables are not only easy to grow, but once planted, they can keep growing for a long time, even producing harvests from several months to a year. Plant once, harvest long-term, very easy and simple, and quite productive too.
Just grow these vegetables on the balcony: plant once and they can grow for a year, fast-growing with continuous harvests
Garlic chives
It is a very easy potted vegetable to grow. Not only can you sow it from seed, but a simpler and faster method is to grow it from garlic chive roots. An ordinary flower pot can be used to grow garlic chives; you can even use empty oil jugs or large drink bottles filled with soil to grow them. With more base fertilizer such as chicken manure or sheep manure, garlic chives grow especially vigorously.
One pot of garlic chives can keep growing for at least three to four years. As long as you water with a bit of fertilizer after each harvest, it will keep growing again. One crop after another, you can pick and eat them all year round.
Mint
Mint leaves can not only be brewed as tea, but some friends also like to use them in cooking. Mint can be grown hydroponically or in soil. The planting method is very simple: just pick a few branches, stick them into the potting soil, and keep them moist and shaded.
Wait until roots have grown before giving them sunlight. Be sure to regularly add fertilizer and water, and prune them often. They will easily grow into a full pot. Plant one pot, and next year they will keep growing again. Pick the leaves whenever you want to eat them.
Sweet potato shoots
Sweet potato leaves are a very nutritious "queen of vegetables," and they taste even better than water spinach. They are also very easy to grow. You only need to plant a sprouted sweet potato in a flower pot, or grow it hydroponically in a bottle. Give it a bit more organic fertilizer and place it in a sunny spot on the balcony, and it will grow especially vigorously, with plenty of vines.
Plant it in spring, and you can keep harvesting until late autumn. You can keep picking leaves to eat throughout the year. Very practical.
Jerusalem artichoke
Many friends saw this vegetable when they were children. Actually, it is really easy to grow and almost needs hardly any care. After one year of planting, you will have a harvest every year afterward. Grown in a flower pot as a potted plant, it can also produce beautiful yellow flowers.
In autumn and winter, you can dig the Jerusalem artichokes out of the soil. Whether pickled or eaten raw, they are very tasty.
Celery
Usually the celery we buy comes as whole stalks. Actually, if you plant several in a flower pot, you can use the sowing method, or you can plant celery roots in the soil.
For the leaves that grow, pull off the outermost leaves to eat. Pulling a few leaves from each plant is enough to stir-fry a plate. Plant more, and you can eat them for several months.
