At what temperature can Chinese rose be fertilized?

In the process of planting Chinese rose, we will find that Chinese rose is a plant that likes water and fertilizer very much. As long as we apply fertilizer reasonably, the Chinese rose we grow will flourish.

However, in the growth stage of Chinese rose, it will enter a high-temperature dormancy period with the increase of temperature, and will be in a low-temperature dormancy period with the decrease of temperature. Therefore, these two stages of fertilization should be very cautious.

First of all, Chinese rose is in high temperature dormancy in summer. How to fertilize? Can it be fertilized?

Especially when the rose is planted at home, it will have a growth stagnation period in the high temperature stage in summer, especially when the temperature is higher than 35℃, which is called the high temperature dormancy period of the rose.

This is mainly because potted Chinese rose flowers have less soil and thin flowerpots, which are easy to be exposed to the sun in summer. At this time, the root system of Chinese rose will have a physiological dormancy due to its own protection, that is, it will grow slowly, will not bloom and will not grow new leaves. This can reduce the transpiration of Chinese rose to the greatest extent, thus ensuring the water balance of Chinese rose, so fertilization is not recommended at this time.

Moreover, if it is a locally grown rose, it will not hibernate under the high temperature in summer. Because the soil temperature is moderate and there is often enough water supply, the rose planted in the ground will not sleep at a high temperature of about 35 degrees. As long as the water and moisture are well preserved, it is no problem to fertilize in the high temperature state in summer at this time.

Second, the rose goes into dormancy at low temperature. How to fertilize at this time? What fertilizer should I apply?

For example, in northern China, when the temperature is lower than 5℃, the rose flowers will be dormant at low temperature in winter. When the temperature is lower than 0℃, the leaves have fallen off, the buds have stopped sprouting and the roots have been dormant.

Fertilization can be carried out at this time, but at this time we need to use some slow-release fertilizers, that is, some fertilizers with low fertility but long fertilizer efficiency. Then we mainly choose fermented organic fertilizer and granular slow release fertilizer, and mainly use base fertilizer to fertilize roses in the way of fertilization.

Thirdly, when the temperature is between 15℃ and 25℃, the fertilization effect is the most obvious in this period.

Because the suitable growth temperature of Chinese rose is between 15℃ and 25℃, the roots, leaves and branches of Chinese rose grow very rapidly during this period, so it is most suitable for us to apply fertilizer at this temperature and the effect is the most obvious.

At this time, fertilization can be based on balanced fertilizer, that is, nitrogen, phosphorus and potassium, to ensure the supplement of various nutrients in the growth process of Chinese rose in all directions. In this way, the Chinese rose we planted can grow rapidly, with oily green leaves and many flowers.

Therefore, when we fertilize the rose, we should choose different fertilization methods according to the temperature, so as to really play the role of fertilization and let our rose get enough nutrition.
