The editor will answer for you what is the related content of top dressing outside the root in the aspect of green plants, and then let's get to know together.
Speaking of rose fertilization, it has always been said that roses love fertilizer very much, so top dressing is a very important task in the daily maintenance process. For the daily top dressing of roses, we generally use fast-acting water-soluble fertilizers, either灌溉 the roots or spraying on the leaves.
Irrigation of the roots has been mentioned in previous articles, so today I mainly want to talk about the top dressing outside the roots of rose flowers.
What is top dressing outside the root?
Top dressing outside the root, also known as foliar top dressing, is a method of fertilization that involves diluting water-soluble fertilizers to a certain concentration and then spraying them on the leaves of flowers.
What are the benefits of top dressing outside the root?
Compared to root irrigation, top dressing outside the root can avoid the adverse effects of soil on certain nutrient elements and can promptly correct the deficiency symptoms of roses.
In addition, when the roots of roses are full and the nutrients that can be absorbed from the potting soil are limited, using top dressing outside the root is a better method of fertilization.
Moreover, when cultivating rose seedlings, the new roots are tender and often cannot withstand fertilization. In this case, top dressing outside the root can be used to supplement nutrients for the young seedlings.
When can top dressing outside the root be applied?
Top dressing outside the root can be used throughout the entire growth stages of roses, but it should not be used when roses are flowering, as it can cause the rose blossoms to wither prematurely.
Also, when applying top dressing outside the root, it is best to choose a windless sunny day, preferably in the evening.
Compared to root irrigation, top dressing outside the root has a faster effect, similar to the difference between taking medicine and receiving a saline infusion when a person is sick.
Top dressing outside the root is absorbed through the plant leaf gaps, and the effect is very fast, especially when roses show deficiency symptoms, using the method of top dressing outside the root can quickly correct the deficiency symptoms of roses.
Attention should be paid to the following:
The concentration of the fertilizer should not be too high when applying top dressing outside the root, as it can easily cause fertilizer damage. If the concentration is too high, it is very easy for the edges of the rose leaves to dry out.
Although the effect of top dressing outside the root is rapid, it is also important to avoid high fertilization frequency. High fertilization frequency can lead to metabolic issues in roses and also easily cause fertilizer damage.
Compared to fast-acting fertilizers, applying organic fertilizers to roses is the safest and most beneficial for their growth and blooming.
Yesterday, it was mentioned that organic fertilizers include many types, such as liquid fertilizers and solid fertilizers, nitrogen fertilizers, and phosphorus-potassium fertilizers. So, how to use them specifically to benefit rose growth the most?
