What to do if the rose is over-fertilized
Here are some experiences on roses, especially on the issue of over-fertilization in roses. Let's take a look together.
Beginners often encounter the problem of over-fertilization in roses. So-called over-fertilization injury refers to the damage to the plant caused by excessive use of fertilizers. What to do if the rose is over-fertilized? Generally, there are only two methods, which will be mentioned in the following text. First, let's look at the causes of over-fertilization in roses to avoid similar mistakes by flower friends.
The causes of over-fertilization in roses include one: excessive fertilization when fertilization is needed. Two: over-fertilization caused by the use of uncomposted organic fertilizers.
Excessive application of organic fertilizers results in the reproduction of various bacteria and chemical molecules in the fertilizer, which requires a large amount of oxygen and water. This will lead to the plant roots competing for oxygen and water. Eventually, the minimum requirements of the plant roots are not met, resulting in root damage or even death due to oxygen deficiency.
Uncomposted organic fertilizers, when applied to the soil, will decompose and ferment. This process also consumes oxygen and water, while producing heat, the amount of which depends on the type of organic fertilizer. Sheep manure fermentation produces the most heat, reaching about 70 degrees Celsius. Therefore, in addition to consuming oxygen and water and competing with the roots, the high temperature causes even more severe root damage. Thus, using uncomposted organic fertilizers is the most fatal. Of course, cold organic fertilizers (such as cow dung, horse dung, etc.) produce very little heat and do not cause root damage.
If inorganic fertilizers are used excessively, they can cause toxicity of certain elements. Excessive ammonia gas can damage the leaves of plants, which uncomposted organic fertilizers can also cause. When nitrogen fertilizers are used and digested, nitrite accumulates, which can cause nitrite poisoning, resulting in brown roots and yellow leaves. Excessive application of inorganic or organic fertilizers, if insufficient water is present during fertilization, can lead to high soil solution concentrations, making it difficult for root cells to absorb water, or even causing water loss. In such cases, the pressure in the roots is lower than that of the soil solution, causing the liquid in the roots to be pushed upwards under pressure, which disrupts the internal balance of the plant. Moreover, if the soil solution concentration is too high and exceeds the root concentration by a certain ratio, it can reverse and absorb water from the roots, leading to root dehydration. The result is that the branches become wilted and the leaves become droopy.
Now let's talk about what to do if the rose is over-fertilized:
There are two methods of treatment. For minor fertilizer damage, an effective method is to water it more, flood the soil with water, allowing the excess fertilizer to leach out with the water, thus diluting it and mitigating the damage.
The second method is to dig it up, wash the roots, and re-grow the seedlings (when repotting, make sure to change the soil and do not use the original soil).
