Breeding methods and precautions for Fenghua roses

1. Maintenance methods

1. Soil: It prefers to grow in slightly acidic soil. When preparing the soil, you can mix garden soil and coarse sand in a ratio of 3:2. When potting, you can put some base fertilizer in to increase the fertility of the soil.

2. Sunlight: It is a very light-loving plant. When raising it, it needs to be placed in a location with sufficient light. It needs at least half a day of sunshine to meet its normal growth needs. Adequate sunlight can also promote it to bloom more and brighter.

3. Temperature: During the growth period of Floribunda rose, the temperature of the environment has a relatively large impact on it. There is no big problem in spring and autumn, but the main problem is in winter and summer, and high and low temperatures should be avoided as much as possible. If the temperature is below 3℃ in winter, it is best to move it indoors to prevent it from freezing.

4. Watering: It does not require much water. During normal maintenance, just wait until the soil is dry before watering it. During its bud formation period, you need to water it a little more appropriately. After it blooms, it will slowly enter a dormant period, so you need to reduce the amount of watering.

2. Breeding techniques

1. Pruning: When it is growing vigorously, it needs to be pruned properly. When pruning, you first need to cut off its diseased branches, dead branches, etc., and you also need to pinch the top to promote the growth of its side branches to achieve the purpose of more flowering.

2. Repotting: Its growth rate is relatively fast, and it usually needs to be repotted once every 1-2 years. When repotting, try to use a larger one to ensure it has enough space to grow. When repotting, you should cut off the rotten roots appropriately to avoid nutrient loss.

3. Problem diagnosis and treatment

1. Diseases: The possible diseases are black spot or powdery mildew. During normal maintenance, you can spray sulfur mixture appropriately for prevention. If symptoms occur, you need to spray pesticides in time to ensure it grows normally.

2. Pests: The most common pest is the cinnabarinus spider mite. Both the larvae and adults of this pest are very harmful to plants. They will suck the branches and leaves of the plants and damage the leaves. In the early stage of the disease, spraying 2000 times of 25% Leba wettable powder can cure it completely.

IV. Other issues

1. Can it be grown indoors? Floribunda rose is not very suitable for indoor cultivation. Because it needs a well-lit growing environment, and the indoor ventilation is not very good, it is prone to poor growth and bacterial growth.

2. Wintering management: Friends in the north need to take measures to prevent cold in winter. It may become diseased when the temperature is below 3°C in winter, so try to grow it indoors. Try to meet its light needs as much as possible and place it in a place with good lighting, such as a balcony, for maintenance.
