Understanding the importance of soil acidity and ways to increase the acidity of potted soil. As an important part of interior decoration, potted plants can not only beautify the environment, but also cultivate sentiment. Many potted lovers will encounter insufficient soil acidity during the maintenance process. The problem directly affects the growth and flowering of plants. This article will provide you with a detailed introduction to how to effectively increase the acidity of potted soil and make your potted plants grow healthier. Understand the importance of soil acidity Soil acidity is one of the important factors affecting plant growth. Appropriate soil acidity can promote plant roots to absorb nutrients and improve plant disease resistance. Most potted plants have suitable soil acidity between pH 5.5 and 6.5. The following are some common potted plants and their suitable soil acidity: 1. Orchids: pH 5.5-6.5 2. Succulent plants: pH 6.0-7.0 3. Flowers and plants: pH 5.5-6.5 4. Herbs: pH 6.0-7.0 Methods to increase the acidity of potted soil 1. Use of acidic fertilizers There are many fertilizers on the market specially designed for acidic soil, such as ammonium sulfate, ammonium nitrate, etc. These fertilizers can effectively increase soil acidity. When using, apply them in accordance with the proportions specified in the instructions to avoid excessive amounts.
2. Add acidic substances (1) Ferrous sulfate: Sprinkle ferrous sulfate powder evenly on the soil surface, and then water it to dissolve. Ferrous sulfate is a commonly used acid regulator that can effectively reduce soil pH.
(2) Organic acids: such as citric acid, acetic acid, etc., dilute these acidic substances, evenly spray them on the soil surface, and then water them.
3. Improve soil (1) Use humus soil: humus soil is an acidic soil that can be used to improve alkaline soil and increase soil acidity.
(2) Adding peat: Peat is an acidic substance that has good water retention and air permeability and can increase soil acidity.
4. Choose suitable plants Select plants suitable for growth in acidic soil, such as orchids, succulent plants, etc., to avoid growth problems caused by insufficient soil acidity. Precautions 1. Regularly test soil acidity and adjust fertilization and soil improvement measures according to actual conditions.
2. Avoid excessive use of acidic fertilizers and acidic substances to avoid excessive soil acidity and affecting plant growth.
3. Pay attention to the fertilization time and avoid applying fertilizer during the period of vigorous plant growth to avoid affecting plant growth.
Through the above methods, you can effectively increase the acidity of potted plants, create a suitable growth environment for your potted plants, pay attention to the growth conditions of plants, and adjust maintenance measures in a timely manner to make your potted plants healthier and more beautiful.
