How to raise miniature rose culture methods and matters needing attention

Miniature rose is a common variety of rose, its shape is relatively small, so it has this name. The ornamental value of miniature rose is very high, and it is very popular with consumers on the market at present. Many people want to breed it, but before breeding, everyone must have a comprehensive understanding of its breeding method.

How to raise miniature rose

1. Lighting: if you want the miniature rose to bloom continuously, you need to give it a long time of light. Under the condition of all-day sunshine, the rose can grow healthily. Except for the appropriate shade when the summer temperature is high, the potted rose can receive all-day light at other times.

2. The most suitable growth temperature of miniature rose is 18-20 ℃, so the flowers are larger and colorful in April-May and September-October every year. With the increase of temperature, when the temperature is stable at about 30 ℃, the color of the flowers is small, the taste is light, the ornamental value is low, and they are vulnerable to diseases and pests.

Culture methods and matters needing attention of miniature rose

1. Culture methods:

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. Miniature 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. Reproduction. The propagation of miniature rose mostly adopts the method of cutting propagation, and it can also be divided and striped. Cuttage can be carried out all the year round, but it is suitable for stem cutting in winter or autumn, and attention should be paid to water management and temperature control in summer. At the same time, grafting can also be used to propagate. Thornless rose is commonly used as rootstock, branch grafting is carried out in early spring or bud grafting is carried out in growing season, especially the bud grafting effect is better.

2. points for attention:

Turn the basin every 1 to 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.

How to trim miniature rose flowers

1. First of all, in the flowering period of the miniature rose, the flowers should be cut off 8-12 cm together with the branches under the flowers. Re-pruning is needed before spring germination, generally retaining 3-4 main branches and 3-5 cm at the base of each branch.

2. Secondly, pay attention to the timely removal of miniature rose remnants, which is a necessary work, which can concentrate nutrients, promote more flowers and long florescence. Otherwise, some axillary buds next to the residual flowers are easy to germinate, and then produce weak branches, which not only consumes the plant nutrients, but also destroys the plant shape, and most of the flowers are deformed or poor florets.

Insect pests of miniature rose and its control

1. Aphids. Prevention and treatment: aphids will gather on the buds, tender leaves and buds of the rose to suck their juice, and in severe cases there will be nectar-like black secretions to reflect the quality of the flowers and the growth of the rose. When aphids lay eggs in autumn and winter, imidacloprid and avermectin can be used alternately.

2. Thrips. Prevention and treatment: when thrips live in young leaves, they will die at the top, resulting in inability to grow. If it feeds at the back of the leaf and excrete brown substance, it will deform the back of the leaf, and gray or grayish brown stripes will appear on both sides of the midrib, deforming and bending. Can spray medicament to carry on the treatment, choose to contain imidacloprid, acetamiprid, thiazine and other active ingredients.

3. Ye Feng. Prevention and treatment: the larvae nibble up the leaves of the rose, produce holes, feed very fast, and in serious cases, they will gnaw away all the leaves and even tender shoots. Drugs such as phoxim and perchloromethyl salt can be sprayed at the initial stage of the occurrence of insect pests.

Miniature rose must pay attention to the temperature of light when breeding, and do a good job here when it is hot in summer. In aquaculture, the amount of fertilizer and water also needs to be controlled, and timely pruning is the inevitable guarantee of its growth. Only by doing a good job can we make it grow healthily.
