It is relatively strong, like warm and dry climate, so the general humidity between 18 to 26 degrees is the most appropriate, in the winter can keep the temperature above 15 degrees, it will keep blooming throughout the winter. Once the temperature can not be guaranteed, it will let all its leaves fall, thus entering the state of dormancy, so the temperature must be controlled.
In order to cultivate more and better Rosa davurica, the commonly used methods are seed propagation and Cuttage Propagation. Of course, different propagation methods are used, and the propagation time is also different. If it is seed propagation, it is generally in the first ten days of September to pick fruits and take out seeds. Cutting is the first ten days of July in each year to collect seedlings and start cutting. Generally speaking, it's better in autumn, no matter which way it can survive.
When it grows well, it is usually topdressing every first half of a month. It is OK to use some organic liquid fertilizer or compound fertilizer, but in winter, it can reduce fertilizer properly. If it is in the greenhouse, it can continue to apply fertilizer, if not, it can reduce fertilizer.
Of course, every plant and disease and insect pest is the most troublesome. For example, the most common disease and insect pest encountered by Rosa davurica is the damage caused by such pests as powdery mildew and leaf borer. It will cause great damage to the leaves of Rosa davurica. At this time, we need to use some drugs for timely spraying treatment. The earlier we find it, the better we can control it, so that we can reduce the damage to it. Come on, let it grow healthily. So diseases and insect pests must not be underestimated.
