If it is hard to grow flowers and love yellow leaves, it is better to use it for 3 yuan a bag for a few years.
Friends who grow flowers all know that no matter which flower pot is planted, yellow leaves are most likely to appear, such as rich bamboo, gardenia, asparagus, and so on. Once yellow leaves appear, the ornamental effect is greatly reduced, so in the face of the problem of yellow leaves, it must be solved in time.
Most of the yellow leaves of many flowers are due to lack of nutrients, so self-made flower fertilizer is a waste of time, and it smells bad, so you might as well buy a bag of ferrous sulfate, three yuan a bag, one bag is good enough for several years, and save energy!
Why can ferrous sulfate prevent and treat yellow leaves? Because ferrous sulfate is a common iron fertilizer, it is also known as green alum. After diluting ferrous sulfate, it can be used to irrigate roots or spray leaves, which can change the acidity of the soil, make the soil acidic, and improve the utilization rate of iron ions in plants. Promote the plant to synthesize chlorophyll and prevent yellow leaves.
The dilution ratio of water to water can be 100%. If you use it every 30 days, it will have a good effect, so since ferrous sulfate is so effective, why make your own flower fertilizer?
Of course, the appearance of yellow leaves is not all caused by lack of nutrients, but also has a lot to do with light. in the case of sufficient light, the leaves can fully carry out photosynthesis and synthesize chlorophyll, which will avoid yellowing and reduce the probability of yellow leaves.
That's all for today.
