Understand the importance of soil pH. Method for measuring soil pH. Method for adjusting soil pH. Soil pH requirements for common potted plants Potting plants are green decorations in many homes and offices. They not only beautify the environment, but also purify the air. To make potted plants grow vigorously, the pH of the soil is crucial. This article will introduce you in detail the acid-alkaline method of potted soil to help you easily master the soil pH and raise healthy potted plants. Understand the importance of soil pH. Soil pH is one of the key factors affecting plant growth. Different plants have different requirements for soil pH. Appropriate soil pH can promote the absorption of nutrients by plant roots and improve plant resistance. Ability to ensure the healthy growth of plants. Method for measuring soil acidity and alkalinity 1. Use pH test paper: pH test paper is the easiest method to determine soil acidity and alkalinity. Mix soil samples with water in a certain ratio, dip them with pH test paper, and compare them with a standard color card to obtain the pH value of the soil.
2. Use a pH meter: The pH meter is a more accurate measurement tool that can directly read the pH value of the soil. When in use, you only need to insert the electrode into the soil sample to obtain an accurate pH value. Method for adjusting soil pH 1. Adjust the soil pH (make the soil alkaline): You can use alkaline substances such as lime and plant ash, mix an appropriate amount of alkaline substances with the soil, and stir well.
2. Lower the soil pH (make the soil acidic): You can choose acidic substances such as ferrous sulfate and aluminum sulfate, mix a suitable amount of acidic substances with the soil, and stir well. Soil pH requirements for common potted plants 1. Camellia: pH 5.5-6.5, slightly acidic soil.
2. Orchids: pH 5.5-6.5, slightly acidic soil.
3. Plum blossoms: pH 5.5-6.5, slightly acidic soil.
4. Adiantum: pH 5.5-6.5, slightly acidic soil.
5. Violet: pH 6.0-6.5, slightly acidic soil.
Mastering the acidic and alkaline method of potted soil will help us better maintain potted plants. By measuring the soil pH and adjusting the soil pH according to the needs of plants, potted plants can grow healthier. During the maintenance process, we also need to pay attention to the following points: 1. Choose soil suitable for plant growth.
2. Regularly apply fertilizer to ensure sufficient plant nutrients.
3. Water in time to keep the soil moist.
4. Pay attention to pest control to ensure plant health.
