Some plants are the typical “vinegar of vinegar,” and sometimes pouring some acid into them can result in glossy green leaves appearing in the pot. If a plant is deficient in acid, it’s hard to believe that the leaves will turn yellow, the tree will die, and it won’t grow or flower.
Therefore, if you keep some common flowers and plants at home, if you can not take care of the soil well, you should occasionally pour a little vinegar on it, watering once every two weeks to keep the leaves green, sprout and sprout. Do it right, you don’t have to worry about the flowers getting damaged.
First, hydrangeas
Hydrangeas are very popular flowers in recent years. There are many varieties of hydrangeas, especially frost-resistant ones. Both the South and the North are suitable for growing hydrangeas, which often require a lot of nutrients to grow quickly. Cauliflower loves acidic soil, acidic soil, blue flowers, especially very beautiful.
However, if the alkalinity is too high, the hydrangea leaves will turn yellow, the seedlings will not grow again, it is necessary to maintain a suitable pH for normal plant growth.
Hydrangea usually grows very quickly and absorbs a lot of acid and elemental iron, so it is necessary to add iron sulfate regularly, otherwise, when planted in the north, the tree is prone to hardening, leaves turn yellow, does not grow, does not flower. . If you have ferrous sulfate or aluminum sulfate at home, you can use them regularly, watering at least once a month and using them as they grow.
But if you don’t spend a lot of time at home, you can add a little vinegar when watering, vinegar has an acid that can regulate the pH of the soil and help the soil not to become alkaline, to prevent yellowing of the leaves. . leaves, otherwise the leaves will be yellow, unruly, hydrangea leaves are green and oily, with strong photosynthesis, so they can secrete enough nutrients to supply, absorb and provide flowering plants.
Second, rhododendron
Rhododendrons prefer a warm, humid environment in the south, and their relatively thin leaves require a moist environment. It is an easy plant to grow, has a greenish red color and is also a distinctive vinegar pickle. This is a representative of acid-loving flowers. The root system of the plant is not developed, often acidic soil is needed for growing azaleas.
If rhododendrons grow in the North, it is best to water ferrous sulfate once a month in a ratio of 1:1000 to avoid iron deficiency and soil alkalinization, if iron sulfate is not present, you can also pour a little vinegar . At a ratio of 1:1000, watering once or twice a month can effectively increase soil pH and prevent leaves from becoming alkaline and yellowing.
Third, camellias
Camellia is a beautiful ornamental flower and one of the world’s famous prized flowers and plants. Camellia is well known in the South, prefers acidic soils and loves vinegar.
Camellia flowers are very beautiful, the leaves are dark green and fresh, the four seasons are always green. It takes a lot of work to grow camellia indoors. First of all, the soil should be loose and aerated, especially slightly acidic soil, it is best to add half of the pine needle soil to the soil to adjust the soil pH.
As the plant grows, water the ferrous sulfate once a month to prevent yellowing of the leaves from iron deficiency. Otherwise, you can add a little vinegar when watering, which can strengthen the plant’s resistance, make the leaves greener, and photosynthesize more strongly, resulting in more flowering.
