Roses are very common in our daily life. Many people like to plant some roses because of their gorgeous flowers and their effects of promoting blood circulation, regulating menstruation, reducing swelling and detoxifying. So do roses need to be fertilized in winter? What kind of fertilizer can make roses grow more and bigger? Let's take a look.

Do roses need to be fertilized in winter?

Whether roses need to be fertilized depends on whether you are from the south or the north. If you are in the north, it is the dormant period of roses and you don't need to fertilize. Even watering should be reduced as much as possible to avoid root rot. If you are in Guangdong in winter, it is the peak season for rose growth and flowering. At this time, roses consume a lot of nutrients and you must fertilize, but you must apply thin fertilizers frequently. It is best to spray one thousandth of potassium dihydrogen phosphate on the leaves to promote flowering and bud formation.

What fertilizer should be used to make the roses grow more and bigger?

1. Roses begin to recover in spring, which is the best time to fertilize them. It is recommended to apply well-rotted organic fertilizer, such as cow and sheep manure, to ground-planted roses.

2. You can choose a circular fertilization point 20 cm away from the root of the rose, dig 20 cm deep, fill it with well-rotted cow and sheep manure, and then cover it with soil.

3. In summer, as the temperature gradually rises, the frequency of fertilization should be reduced or stopped. Autumn is also the golden period for roses to absorb fertilizers, and organic fertilizers should be applied every 15 days or so. In winter, in order for roses to survive the winter safely, it is recommended to apply enough winter fertilizer.

How to prepare fertilizer for rose cultivation

The reason for fertilizing is to provide nutrients for the growth of roses in time. However, if too much fertilizer is applied at one time or it is too concentrated, the concentration of the soil solution will be greater than the concentration of the root hair cell sap, resulting in the water in the root hair cell sap penetrating into the soil solution. In this way, the root hair cells not only cannot absorb water, but also lose water, causing the roses to wilt. Therefore, the amount of fertilizer and what kind of fertilizer to apply should be determined according to the different conditions of the roses.
