1. Cause

① Acidity

When it comes to why this plant can be watered with vinegar, the most fundamental reason is that it is suitable for growing in weakly acidic flower soil. Vinegar contains acetic acid. Watering with it can maintain the pH of flower soil between 4.0-6.5, which is the favorite of this kind of flowers. This can not only make it grow faster, but also make it grow healthier

② Nutrients

In addition to acidifying flower soil, it contains many nutrients, which is also a very important reason. Specifically, vinegar contains a small amount of Fe, Ca and other elements, which can help the formation of chlorophyll, increase the efficiency of photosynthesis and improve the nutrient accumulation efficiency of plants. Therefore, watering it with vinegar can make it grow better

2. Precautions

① Dilution

This is a very important point. Please don't ignore it. When watering it with vinegar, be sure to dilute it in advance, otherwise high concentration vinegar may cause damage to its roots. We generally need to dilute the vinegar to more than 100 times, and prefer thin rather than thick

② Frequency

It needs to pay attention to the frequency of watering with vinegar. It must not be watered every day. Generally, it can be watered once every seven days. If the plant has adverse phenomena such as yellow leaves and wilting leaves, you can increase the frequency of watering as appropriate, but not more than once every three days

③ Salt free

Now, in order to make the taste of vinegar more in line with everyone's taste, many manufacturers will add some NaCl to the vinegar, that is, what we call salt. This may not be a problem for us, but it's not good for the plant. Once the flowers are watered with this vinegar containing NaCl, these sodium ions will dissolve in the water of the flower soil and change the osmotic pressure. This kind of flower uses osmotic pressure to absorb water and some nutrients. Once the osmotic pressure changes, they cannot absorb these substances normally, which affects the development of plants
