How to fertilize the leaves of Chinese roses

This article introduces the related introduction of fertilizing the leaves of Chinese roses, and then let's understand together.

The main method of fertilization is through the roots (G-Y) via the soil with plant fertilizers. In addition to this, there is also a method of foliar application of liquid fertilizers to directly promote the growth of Chinese roses, especially when the soil conditions are not conducive to the growth of Chinese roses, this method can achieve significant results.

After foliar fertilization, the plant has more branches, larger volume, stronger and more disease-resistant, the number of flowers increases by 20% to 30%, and the color of the flowers is more beautiful. Especially in early spring when the temperature is low and the plants have not absorbed sufficient nitrogen fertilizer from the soil, the effect of foliar fertilization is more significant. However, it should be noted that this method can only play a supporting role and cannot replace conventional soil fertilization.

Foliar fertilization is a method that allows the fertilizer dissolved in water to gradually penetrate into the leaves through the stomata on the leaves or the cuticle on the leaf surface and take effect on the plant. Therefore, ensuring that the fertilizer can smoothly enter the leaves is the key to foliar fertilization. The following points should be noted when applying:

① Not all fertilizers can be used for foliar fertilization, only inorganic fertilizers with good solubility can be used, such as commonly used urea, ammonium sulfate, ammonium nitrate, potassium chloride, superphosphate, etc.

② It is best to carry out foliar application in the early morning or evening when the temperature is low, humidity is high, and there is no wind, so that the fertilizer solution can remain on the leaf surface for about an hour without drying, allowing the fertilizer to fully penetrate into the leaves.

③ Young leaves absorb faster than old leaves, and the back of the leaves absorb faster than the front. When fertilizing, be sure to spray the crown and back of the leaves of the plant.

④ It can be sprayed together with insecticides and fungicides to achieve the dual effect of supplying nutrients and controlling pests and diseases.

⑤ The fertilizer used should be pre-soaked before spraying to ensure it is fully dissolved, removing impurities and sediments. The speed at which fertilizer enters the leaves is related to the concentration of the fertilizer solution; the lighter it is, the easier it is to penetrate, but too light will also reduce the fertilizer effect. Generally, it should be diluted with more than 100 times water by weight.

⑥ To ensure that the fertilizer solution can adhere to the leaf surface (especially the back of the leaf), it is best to use a fine-mist spray bottle for application.
