Matters needing attention in breeding miniature Chinese rose

Miniature rose is easy to suffer from diseases and insect pests in the process of culture, and the main diseases are powdery mildew, gray mold, black spot and so on. At this time, we can carry out scientific cultivation to prevent and control, spray 5 Baumetu stone sulfur mixture before germination to enhance plant disease resistance and remove dead branches and leaves in time.

Miniature rose culture methods matters needing attention in miniature rose culture

Miniature rose is a small potted plant, beautiful in color, very ornamental, so many flower friends will breed indoors. So, how to raise miniature rose? What do you need to pay attention to when breeding? The following is to introduce the miniature rose culture methods and matters needing attention.

Culture method of miniature Chinese rose

1. Watering:

The small roots of miniature rose plants are shallow. Before germination in spring, the basin soil should be kept moist, and the soil should not be watered. After germination, the amount of water should be gradually increased. Generally, it should be watered once before 10:00 in the morning and properly in the afternoon according to the dry and wet condition of basin soil. In summer, water should be watered once in the morning and evening, but not at night.

2. Fertilization:

Mini rose likes fertilizer. When the growth is exuberant in spring and autumn, topdressing once every 10-15 days, both organic fertilizer and compound fertilizer can be used. Fertilization should be stopped in high temperature season in summer and low temperature in winter.

3. Maintenance site:

It should be placed in a place with sufficient light and air circulation, and should be properly shaded when it is hot in summer. Miniature rose is more hardy and can be put outdoors in winter.

4. Pruning:

After the flower fade, part of the branches should be cut off, leaving the new branches 2-3 nodes and then cut off, and more than 2 nodes of the cut branches should be used for cutting propagation. Winter pruning is mainly plastic pruning, first cutting off withered branches, disease and insect branches, cross thin and weak branches, and for plants with strong growth and symmetrical plant type, cut off 1 inch of the whole plant. For the plants with weak growth, about 2% of the whole plant was cut off, leaving 3-4 strong main branches.

5. Turn the basin:

Turn the basin every 1-2 years, remove about 2% of the old soil, and replace it with loose, fertile soil rich in organic matter. It is mostly carried out before sprouting in spring, combined with turning the basin, cutting off withered roots, rotten roots and disease and insect roots, cutting too long roots, thinning out dense roots and part of old roots, promoting its germination of new roots and making its growth exuberant.

6. Pest control:

Prevention and cure of ⑴ disease. The main diseases of miniature rose are powdery mildew, gray mold, black spot and so on. The main control methods are to carry out scientific cultivation, enhance plant disease resistance, remove dead branches and leaves in time, spray 5 Baomedushi sulfur mixture before germination, spray 800 times of 70% methyl topiramate every half a month after germination, and spray 3-4 times continuously.

⑵ pest control. The common pests of miniature rose are aphids, red spiders and leaf-cutting wasps, which can be sprayed and killed with 1000 times of dimethoate EC or 45% malathion.

Matters needing attention in miniature rose culture

1. Select basin and medium. Because the miniature rose plant is short and shallow, it is appropriate to choose a tile basin with a diameter of 18cm and 20cm when planting. The cultivation medium is rich in organic matter, loose and fertile soil with good permeability. If clayey or calcareous soil is used, the light ones will grow poorly and the heavy ones will die.

2. Proper management of water and fertilizer. Because the branches and leaves of miniature rose are small, so less water is required, so it is appropriate to keep the basin soil moist in growing season. Too little watering will lead to poor growth; too much watering will easily lead to rotting roots. Like fat chat, if you want to make it blossom frequently, you should constantly replenish nourishment. When applying fertilizer, we should grasp the principle of applying thin fertilizer frequently. During the growth period, we generally apply mature thin cake fertilizer and water every half a month. For example, if 0.2% potassium hydrogen phosphate solution is sprayed once or twice during the bud period, the flower color will be more beautiful. The plant is in a semi-dormant state in the midsummer season, so fertilization should be suspended.

3. Trim regularly. In order to produce more flowers all the year round, it is necessary to constantly cut off the old branches and promote the germination of new ones. Early spring combined with basin change (usually once every two years) for moderate pruning. Generally, only 3-4 main branches are retained, and each main branch is 3-5 cm long from the base. if the upper branch is cut off, more new strong branches can sprout, forming a full plant shape with luxuriant branches and leaves and continuous flowering. Cut off the residual pedicels in time after flower fade, in order to reduce nutrient consumption and promote the development of new branches.

4. Miniature rose belongs to positive flowers and trees, which grow healthily under the condition of full sunshine, and the flowers are colorful. Therefore, when pot culture, in addition to blooming indoors for a few days, the growth period should be placed on the south-facing balcony or the sunny part of the courtyard to receive sufficient light. Northern summer festival illumination is big, need appropriate shade around noon, then grow better, and potted rose, need to move into the indoor winter after winter.

The above is for you to introduce the miniature rose culture methods and matters needing attention, is everyone clear? Please pay attention to more household knowledge.

Soil, the culture method of miniature rose

Miniature rose flowers like to grow in sandy soil with fertile soil and good water retention. If the soil is poorly drained, the soil is hardened. It is very disadvantageous to its growth and may even lead to its death. The soil with more limestone will also affect the absorption and utilization of some trace elements by rose, resulting in chlorosis.

Light

Miniature rose likes light, and it can be illuminated properly during the day, which is beneficial to its growth. But in hot summer, if there is too much direct light, it will also be disadvantageous to the development of buds, and the petals are easy to scorch. So we have to remember to avoid the direct sun.

Fertilizer application

Mini rose has a long flowering period, basically blossoms throughout the year, and has a large demand for nutrients, so it is more fond of fertilizer, so we need to fertilize it every month to ensure adequate nutritional conditions.

Temperature

The suitable temperature for the growth of miniature rose is 15 to 26 degrees. Avoid overheating in summer. If the temperature exceeds 33 degrees, it should be properly shaded. If you want better maintenance in summer, you must maintain good ventilation. The ground can spray water to cool down, but avoid spraying on the leaves.
