Citric acid is a common organic acid widely used in food, pharmaceuticals, cosmetics, and other fields. But did you know it can also be used to water flowers? This article will introduce you to the role of citric acid in the garden and how to use it.

What is citric acid?
Citric acid, with the chemical formula C6H8O7, is a colorless crystal with a slightly acidic nature. It can be extracted from citrus plants or obtained through chemical synthesis. Citric acid is widely used in food, pharmaceuticals, cosmetics, and other fields.
The pH value and concentration of citric acid
The pH value of citric acid is approximately 2.5, making it a moderately acidic substance. When used in the garden, its concentration needs to be noted. Generally, a concentration of 1-2% is sufficient for most flowers. If the concentration is too high, it may burn the leaves and affect the growth of the flowers.

The role of citric acid
Citric acid can improve the soil's pH level and promote plant growth. It can also enhance the nutritional value of the soil and increase its organic matter content. In addition, citric acid can help plants absorb nutrients and enhance their disease resistance.
Applicable flower species
Citric acid is suitable for most flower species, including tulips, roses, sunflowers, chrysanthemums, etc. However, some species may be sensitive to acidic substances and require careful use.
Usage methods
Dissolve citric acid in water and spray it on the leaves at a concentration of 1-2%. Ensure even coverage during spraying to avoid missing any spots. It is best to spray in the morning or evening to avoid the effects of direct sunlight.

Precautions
1. Citric acid should not be mixed with fertilizers or pesticides to avoid adverse reactions.
2. When using citric acid, protect your hands and respiratory tract to avoid discomfort.
3. Do not spray citric acid on flowers during their blooming period to avoid affecting their appearance.
The advantages of citric acid
Using citric acid to water flowers can improve soil texture, promote plant growth, and enhance disease resistance. Compared to chemical fertilizers, citric acid is more environmentally friendly, safer, and healthier, with less harm to the human body and the environment.
The disadvantages of citric acid
Using citric acid to water flowers requires certain skills and knowledge; otherwise, it may affect the growth of the flowers. Furthermore, the effects of citric acid may not be as pronounced as chemical fertilizers, and long-term, continuous use is required to see results.
Combining citric acid with other solutions
Citric acid can be used in combination with solutions such as lime and ammonium sulfate to have a synergistic effect. However, it is important to pay attention to the concentration and ratio of the two solutions to avoid adverse reactions.
The scope of application of citric acid
Citric acid can not only be used for watering flowers but also for cleaning, disinfection, decalcification, and other fields. It can be said to be a very practical chemical.
Storage method for citric acid
Citric acid should be stored in a dry, ventilated, and cool place. Avoid direct sunlight and high-temperature environments. Keep it away from fire sources and flammable materials to prevent danger.
The price of citric acid
The price of citric acid is relatively low, generally around 10 yuan/kg. Due to the small amount used, a bottle of citric acid can generally last for a long time.
The safety of citric acid
Citric acid is a relatively safe substance, but when using it, it is necessary to protect your body and respiratory tract to avoid discomfort. If discomfort symptoms occur, stop using it in a timely manner.
The environmental friendliness of citric acid
Citric acid is a green and environmentally friendly chemical that does not cause pollution or harm to the environment. In contrast, chemicals such as chemical fertilizers and pesticides are more harmful to the environment.
Citric acid is a very practical substance that can be used in multiple fields such as watering flowers, cleaning, and disinfection. Using citric acid in the garden can promote flower growth, enhance their disease resistance, and is more environmentally friendly, safe, and healthy. However, when using it, attention must be paid to aspects such as concentration, usage methods, and precautions to avoid affecting the growth effect of the flowers.
