1、 How to make

1. Burying acid humus: when making acid soil, you can bury some acid humus into the soil, such as rotten pine needles, residual branches and leaves, or directly mix it with humus soil. In this way, it can be absorbed and fused by the soil and change the pH value of the soil, so as to make acid soil

2. Fermented peel solution: when eating fruit at ordinary times, collect the remaining peel, wash it, put it into a container, add water and ferment in the sun, take out the fermented solution, then add water to dilute and water it into the soil, which can not only make acidic soil, but also enhance fertility

3. Add vinegar: prepare vinegar, add water, mix and dilute it, and then spray it on the soil surface. Don't use too much at one time. Pay attention to detect the pH value, and it can be made in a few days

4. Ferrous sulfate solution: ferrous sulfate is acidic and can improve the pH value of the soil. Mix ferrous sulfate powder and clean water in the ratio of 1:1000, and then pour it into the soil. Pour it 2-3 times a month to make acidic soil

2、 What flowers are suitable for growing

Acid soil is suitable for planting acid loving southern flowers, such as gardenia, big rock Tung, azalea, hydrangea, Milan flower, camellia, etc
