These 4 green plants wilt without acid; when gardening in the south, don't forget to add acid

Southern friends who have grown flowers have surely noticed that some flowers look easy to keep, but after bringing them home, within a few days the leaves turn yellow and the buds drop. It's not that you forgot to water or fertilize; most likely you forgot to "add acid" for them! Although the southern climate is humid, many potting soils become alkaline over time, and these four common green plants - camellia, osmanthus, gardenia, and jasmine - are famously "acid-loving heavyweights." Without acid, they're like a person who hasn't eaten, and simply won't grow vigorously.

Camellia: the beauty queen of southern courtyards. When it blooms, the flowers are large and abundant - pink, red, white - and just looking at them feels festive. But if you notice its new leaves turning yellow while the veins stay green, that's it calling out that it's hungry for acid. A neighbor grew camellias last year and only knew to water them, so half the leaves dropped. Later, every time they watered, they added a little diluted white vinegar, and within two months new flower buds appeared. Remember, camellias like slightly acidic soil. Don't water them directly with tap water - let it sit in the sun for two days first. Occasionally give them fermented rice-washing water, and the leaves will surely be glossy.

Osmanthus: as soon as autumn arrives, the whole street is filled with the scent of osmanthus. Who wouldn't want to grow one at home? But if osmanthus lacks acid, not only will it bloom less, the fragrance will also be faint, and in severe cases the leaves will slowly wither. I once grew a golden osmanthus on the balcony. At first I didn't pay attention, and that autumn it only opened a few flowers. Later I heard an experienced flower grower say to water it once a month with ferrous sulfate solution, and the soil wouldn't become alkaline. After trying it, it really worked. This autumn the whole balcony was filled with fragrance, and even the neighbor downstairs asked me how I grew it. By the way, osmanthus fertilizer should also be acidic, such as decomposed bean cake fertilizer. Don't use those alkaline fertilizers, or the more you feed it, the more it wilts.

Gardenia: just hearing the name feels fresh, but it is an "acid jar." The most obvious sign of acid deficiency is yellowing leaves and buds dropping before they open. There's also a little trick: when watering gardenias, don't pour water on the petals, or they'll easily rot. Pour it around the potting soil so the roots can absorb the acid, and only then will it grow vigorously.

Jasmine: in summer it blooms abundantly and fragrantly, and can even be brewed as tea, but many people find that as they grow it, the leaves turn yellow and it may even die. In fact, if jasmine lacks acid, not only do the leaves turn yellow, it also doesn't like to bloom, and even if it does bloom, it isn't fragrant. When I grow jasmine, I add a little ferrous sulfate every time I water. Don't make the concentration too high, or it will burn the roots. A ratio of about 1:1000 is fine. In addition, jasmine likes sunlight, but when sunbathing, you must also ensure the soil is acidic. Otherwise, no matter how much sun it gets, it's useless, and it's more likely to get sunburned.

The key to growing these four southern green plants is to remember their "acid-loving" nature. Usually observe the condition of the leaves and flower buds more, and add acid promptly when something seems off. Things like fermented rice-washing water, diluted white vinegar, and ferrous sulfate solution are all good acid supplements - cheap and easy to use. Beginner friends, don't be afraid; you'll gain experience after trying a few times.
