How do you create a balcony garden? A tiny balcony can fulfill your gardening dream
Growing flowers is a patient, meticulous pursuit that requires interest, and it takes a few years of practice to get the hang of it. I suggest starting with just a few kinds to try, so it does not take up too much energy or cost too much money, and then add more year by year. Go for ones with a reputation for being easy to keep alive, but which ones you can actually keep alive is really not certain, you truly have to try.

If you want to grow flowers well, the environment must be set up properly: there must be light, strong ventilation, and as much humidity as possible. This year, because of the house being too hot from the sun and fully south-facing with no ventilation, my roses got bugs, bloomed a few rounds of flowers and then died! If the original poster has an open balcony, then this problem does not exist!
Step one: choose plants according to the balcony's orientation and the duration of light. For an open balcony, choose cold-hardy plants that overwinter easily
--Recommending a few for south-facing and west-facing, there are too many choices--
Woody plants: plant one Japanese red maple in a large pot; one small pine tree; two globe-shaped hollies of different sizes;
Climbing vines: clematis, climbing roses, long bloom period, buy cold-hardy varieties, preferably 3-year-old or older seedlings; morning glory and cypress vine are herbaceous, plant once a year, seeds fall into the pot and sprout on their own the next year.
Upright types: geraniums are a good choice, drought-tolerant and pest-free, with flowers year-round; when it is hot, put them somewhere cool to escape the heat, and when it is cold, move them indoors to overwinter; dwarf sunflowers, sown in spring and harvested in autumn, large pot, lots of fertilizer and water in summer; also miniature roses and European roses, gorgeous to the point of dying
Aquatic: get a big vat to grow water lilies, and also keep a few small fish. Get a big pot to grow water hyacinth. Add some pennywort, place it in a spot with half-day sun.
Trailing types: hanging them from the ceiling is not recommended, watering is very laborious; you can hang them on the railing, petunias, trailing geraniums
Vegetables: choose ones that do not attract bugs easily. Cucumbers and loofah gourd climb walls. Buy an upright multi-tier planter rack and grow spinach, lettuce, cilantro, small scallions... Tomatoes are really not recommended, they attract bugs, love heavy fertilizer, and generally do not set fruit when grown.

--East-facing and north-facing, suitable for plants that need half-day sun or diffused light--
Climbing vines: Madeira vine, so easy to grow it just will not die, tolerant of both wet and dry, its green is especially soothing to the eyes, and it is edible too; in winter cut it right down to the roots and take it indoors to overwinter, and the next year take it out and it covers the railing again. Ivy, overwinters indoors.
Upright types: mint, choose tasty varieties like spearmint and lemon mint; in summer pick a few leaves and mix a mojito, delightful!
A north-facing balcony I set up for a friend, mostly shade-loving green plants, with some light at sunrise and sunset

Step two: choose suitable pots and tools (this is an advanced requirement, but if you want to grow well, there is no avoiding this step)
Pots: size, depth, breathability, determined according to the flower root's growth habits and the age of the flower
Soil: there are too many types, mainly consider high breathability and good drainage; for all the ones recommended above, ordinary soil is fine.
Fertilizer: when first planting you need base fertilizer, during growth you need water-soluble fertilizer and slow-release fertilizer
Pesticides: two kinds, insecticide and fungicide
Step three: look at them every day, spend two hours a week watering, pruning, and occasionally spraying, apply some fertilizer every two months, and repot into a larger pot after two years
ps: growing flowers indoors is really not as good as outdoors; plants are meant to go through the natural baptism of sun and rain, fierce wind and heavy snow, and it is we who forcibly change them for our own sake.
Finally, a few pictures to express what I mean; from an aesthetic angle, let your imagination run free, there is no most beautiful, only more beautiful! May you reach this level within 5 years!
