When do roses bloom?

The natural flowering period of roses is from August to April of the following year.

Rose flower into large, from inside to outside, was divergent type, has a strong aroma, can be widely used in horticultural cultivation and cut flowers.

Rose adaptability is strong, cold, cold, regardless of planting, potted plants can be applied to beautify the courtyard, decorate the garden, arrange flower beds, plant hedges, flower racks, rose cultivation is easy, can be cut flowers, used to do bouquets and various flower baskets

Rose cutting methods:

(1) Cutting propagation

It can be divided into softwood cuttings, hardwood cuttings, full-day cuttings and bud cuttings.

① Softwood cuttings

It grows best in April ~ May and September ~ October, and it is easy to root and survive when the temperature is 2~5℃. In order to promote rooting, the cut can be dipped in indolebutyric acid powder with a concentration of 500 - 750 ml, and the strong flowering branches of the current year can be selected for cutting. After the flowers are withered, the residual flowers and dead leaves under the flowers are removed. After several days, the branches are supplemented and grow fully. After the leaf nodes are expanded, the branches about 10 cm long with 3 - 4 leaf nodes are cut off in the morning, leaving only the upper two compound leaves, and the rest leaves are cut off together with the leaf bucket. The remaining two compound leaves are best left with only the base two leaflets to reduce transpiration. Soil drainage requirements ventilation is good, soil preparation for the ridge, to be soft, cutting distance requirements do not shade for the principle. The depth is 2/3 of the cuttings, and 1~3 buds are reserved on the ground. After insertion, water should be poured thoroughly, and the cuttings should be tightly combined with the soil. After insertion, management should be shaded, and plastic film should be used to keep moisture. At night, it should be uncovered for ventilation. The soil should be kept moist, but it should not be too wet, so as to facilitate sufficient air in the soil to prevent the wound from being mildewed. About half a month, gradually increase the sunlight exposure time to increase photosynthesis and take root. When new buds grow out, old leaves do not fall off, indicating that cuttings have taken root and survived, you can transplant.

② Hard branch insertion

The soil and soil preparation are the same as those of tender cuttings, and cuttings can be carried out until the leaves of roses enter the dormant period until the next spring before germination. Basically strong branches can be used as cuttings, cut 10 cm long branches with 3~4 leaf buds without leaves, pour water after insertion, use branches or other branches, steel bars, etc. to make bow frame, cover plastic film, breeding place should be sunny, be protected by wind to keep moisture, and pay attention to dry, etc. When the cuttings sprout in the spring of the next year, the plastic film is removed, and when the young leaves grow up and turn green, the lower roots can be transplanted after they grow well.

③ bud

Due to the strong growth force of spring sprouts, the survival rate of cutting materials is high. When the sprouts grow to 3~7 cm, they can be gently broken off by hand or cut from the base of the buds with blades. It is best to choose the sprouts that grow strongly, bud head is full and the base of the main branch is issued. After picking, it can be cut after washing with clean water. The soil for cutting is better than breaking ground. When inserting, use a stick slightly thinner than the bud to poke holes. Insert the bud into the hole for 1/3 of the bud length, so that it is close to the soil. Pour water through it. Cover with plastic film to prevent wind blowing. However, the humidity in the cover should not be too large. Ventilate 1~2 times a day to keep the soil moist. After about half a month, it can take root. After 20 days, remove the plastic film and transplant it.

④ Full sunlight cutting

Full sunlight cutting is in the whole cutting process, do not shade, so that it can be sufficient sunlight irradiation, but because the cuttings do not have roots can not carry out normal water absorption, so that it is difficult to absorb water, in order to make the cuttings normal photosynthesis and life activities, we must supplement water from the leaves, often spray water on the leaves, can make the leaves form a layer of water film, not only can make the cotyledon cells meet the needs of water, but also can reduce the leaf temperature, reduce leaf transpiration, In order to ensure the normal photosynthesis, if there is no spraying device, it can be solved by frequent spraying. In the first week after planting, spray water once every half hour, and spray water 2 hours after a week. Therefore, the seedbed of full-sunshine cuttage is dominated by plain sand. After 3 weeks, it can be transplanted.
