Raising roses rich in nitrogen, phosphorus and potassium is not enough?

When raising roses, flower friends will encounter the problem of not knowing how to choose fertilizers. They seem to feel that the fertilizers used in the market are similar and are rich in nitrogen, phosphorus and potassium, but do roses only need nitrogen, phosphorus and potassium fertilizers?

What kind of fertilizer do you need during the growth of rose?

Nitrogen fertilizer

Nitrogen fertilizer can promote plant growth, improve plant short, slow growth, thin leaves, leaf yellowing and other phenomena, but also promote the plant more robust, if the lack of nitrogen fertilizer, the plant will yellowing, short and thin stems, delayed flowering and other phenomena.

Phosphate fertilizer

Phosphate fertilizer can promote the growth and development of roots, improve the ability of index to adapt to the external environment, especially conducive to plant tolerance to low temperature through the winter. Less phosphate fertilizer, the plant will become dark green, red or senior, when the climate is dry, it is easy to appear dark green, leaves yellow, flowering delayed.

Potash fertilizer

Potash fertilizer can improve the resistance of plants, such as drought, low temperature, salinity, diseases and insect pests, lodging, etc., if lack of potassium, old leaves will turn yellow from the edge, and even burn leaves.

Iron fertilizer

Iron fertilizer can greatly improve the yellow leaves of plants, or the loss of green, the color of flowers is not bright enough, and so on, but the absorption of iron is easily limited when high temperature or environmental changes are encountered in summer, so it is best to use leaf spraying in order to make the plant absorb effectively.

Calcium magnesium fertilizer

Nitrogen, phosphorus and potassium are widely used elements, while calcium, magnesium and iron are medium elements and indispensable elements during the growth of rose. If lack of calcium, leaves are easy to yellow, curl, tender tip deformation, rod cracking, fruit cracking and so on. If lack of calcium, it will affect the absorption of magnesium, if lack of magnesium will also affect the absorption of calcium. Lack of calcium is also related to light, lack of light, ultraviolet light will be insufficient, it will affect the absorption of calcium.

In short, in the process of maintaining rose, we must pay attention to the selection of fertilizer, do not use a single nutrient element, conditional flower friends, it is best to choose rose-specific organic fertilizer, put an end to the use of chemical blending fertilizer, plant growth is exuberant in the short term, but in the long run, it is easy to cause plant maladaptation or short life.
