When to fertilize roses and what kind of fertilizer is best

1. When to apply fertilizer

During the management period, it is necessary to fertilize it frequently to supplement the nutrients needed for each growth stage. Only with sufficient nutrients can it grow vigorously. Fertilizer is usually applied four times a year. The first time was around the Qingming Festival in spring. The second time is before picking the flowers, the third time is the topdressing fertilizer in May, and the fourth time is the overwintering fertilizer applied in late autumn and early winter. Each time is indispensable. Of course, the types of fertilizers chosen at each stage are also different.

2. What kind of fertilizer is good?

What kind of fertilizer to apply to it depends on the time of application and the growth stage. The fertilizer applied at different times is also different, but they are all mainly organic fertilizers. Among them, the fertilizer applied during the Qingming Festival in spring is human and animal manure. This is the time when new buds begin to sprout, so it is also called sprout fertilizer. Water should be applied in time after application. Before picking the flowers, flower-promoting fertilizers are applied, mainly a mixed liquid fertilizer of nitrogen, phosphorus and potassium, which can be applied directly to the soil to prolong the flowering period. In May, organic fertilizer is applied. The main choice of winter fertilizer is decomposed organic fertilizer, or long-acting chemical fertilizer, which can increase cold resistance and help survive the winter.

3. Precautions for fertilization

When fertilizing it at any stage, you must pay attention to applying thin fertilizers frequently and not too much at one time, otherwise it will easily burn the roots and cause various fertilizer damage. It is best to water the soil once after application, which can speed up the dilution of the fertilizer and facilitate its absorption.
