How to turn tap water into weak acid for watering flowers (adjust alkaline water into acidic water for watering flowers)

The water used for watering flowers is alkaline, how to make it acidic

In the process of flower cultivation, watering is an essential and important management procedure. However, the alkalinity of water used for watering flowers in many areas is relatively high.

This is very detrimental to the normal growth of flowers. Some acid-loving flowers may even fail to grow or die due to the high alkalinity of the water.

Under normal circumstances, the most suitable soil pH value for most flowers and plants is between 5 and 7.5 .

The soil and water quality are acidic to slightly acidic, which is more suitable for the growth of most flowers. When the alkalinity content of water and soil is above 7.5, it is alkaline.

However, only a few plants can grow in alkaline soil and water, and most flowers cannot survive in such soil.

The following methods can be used to adjust alkaline to acidic

1. Vinegar and water

Mix vinegar with water at a ratio of 250-300 and spray it on flowers and trees. This will make the branches and leaves green and bright. Also, be careful to prevent the acetic acid from evaporating. Spray it in the morning and evening.

In summer, watermelon peel and orange peel are soaked in water for 7-10 days, and in other seasons for 20-30 days. This water is not only slightly acidic, but also contains nutrients such as phosphorus, potassium, hydrogen, and calcium.

3. Citric acid

Adding an appropriate amount of edible citric acid to water can also make the water slightly acidic.

4. Retting acidic water for watering flowers

Cut pine and cypress leaves or green grass into small pieces and put them into a water tank sealed with plastic film for fermentation. Remove the fermented residue and use the supernatant to water the flowers and trees. The effect is excellent.

5. Rice washing water

The rice water after fermentation is not only slightly acidic, but also contains trace elements and rich nitrogen and phosphorus. It is high-quality acidic water for watering flowers and trees.

6. Ferrous sulfate

The blending ratio of ferrous sulfate is usually 1:2000, which means that 1 gram of ferrous sulfate can be mixed with 2 kilograms of tap water.

In addition, the water ratio can be adjusted according to the pH value of the water, and the frequency of irrigation is generally one to two times a month. After a period of adjustment, the alkalinity of the soil will be greatly reduced.
