How do roses reproduce? Methods of propagation of roses

Roses can be propagated by cuttings, dividing and grafting.

The annual branches can be cut into about 10 cm sections, which are inserted in the seedbed between May and June, and the roots will survive in 30 to 40 days. Grafted rootstocks are usually made of roses and seedlings of the moon season, with bud grafting, cutting grafting, and ventral grafting. Dividing is an effective method because roses have the characteristic of becoming more and more vigorous.

The dividing time is generally carried out before budding after defoliation in winter, and it is easy to survive and bloom in the same year.

In order to propagate in large quantities, in addition to cuttings propagation, it can also be propagated with buried strips, mainly in winter or spring before germination, cut off the updated old branches or current branches on the ground before germination, open a ditch and place the branches head and tail together, cover with 10 20 cm topsoil and then cover the grass, in order to keep warm and moisturize. The bottom of the ditch is used as a base fertilizer with superphosphate in advance, which can promote growth, of course, this method of burying strips is only suitable for some varieties that are easy to root. Single-petaled roses produce seeds that can be sown and propagated.

The seeds are dormant and germinate in spring after autumn sowing or sand storage. Seedlings are nurtured and come out of the nursery the next year and bloom in the third year.

It is cheaper to propagate roses with seeds, and if you master the "way" of germination, the germination rate will be higher!

It is mainly propagated by dividing, and can also be propagated by stripping and cuttings.

The propagation of roses is generally carried out by cuttings, and healthy shoots are selected in early spring or autumn equinox, and planted in slightly acidic soil with loose soil, sufficient nutrients and conducive to drainage; It can also be propagated by the strip pressing method; The simplest method of propagation is the dividing method; Finally, seeding can also be used to propagate.

1. Cutting time

Rose cuttings propagation is generally carried out in spring or autumn, and it is best to choose early spring between February and March in spring, when the soil has just thawed, which is conducive to plant cuttings; In autumn, cuttings are usually planted between September and October, when it is rainy season, and the humid climate is conducive to the survival of plants.

2. Soil selection

The cuttings of roses like to be in the loose soil, sufficient nutrients, conducive to drainage of slightly acidic soil, and then spray with potassium permanganate and methyl tobuzin liquid for disinfection, you can also add some humus in it, so that the plant absorbs sufficient nutrients, improve the survival rate.

3. Handle branches

Rose cuttings are generally selected from healthy and thick, insect-free and harmless branches that have grown for more than one year, and the incision at the bottom of the branch is pruned into the shape of a duck's beak with a large cut surface; Then soak the branches in the diluted rooting water, and after 12 hours, apply indole butyric acid to the roots of the branches and put them in the soil.

In addition to cuttings propagation, what are the other methods of propagation of roses, and we can also use the rose striping method to propagate. Cut two centimeters long in the stem of the rose, then wrap a 5 cm diameter soil ball in plastic at the broken skin, spray it with water mist to keep it moist, and after two months new shoots will grow.

Gently dig the mature rose plants out of the soil, then wash the roots with clean water, and then use a sterilized tool to slowly cut the sharp marks along the stems from the roots until they are divided into two plants, and then put the roots of the two new plants and soak them in rooting water for five hours, then they can be replanted into the soil.

The sowing method of roses is generally used for new varieties, the collected seeds are placed in the fertile soil, and covered with plastic film on the surface of the soil, do not water and fertilize in the early stage, wait for two months after the seeds break out of the shell, and then plant them in other soils for maintenance.

Hello, the propagation of roses has the following points, 1. Sowing and propagating: select healthy rose seeds to Jingling, spread them in the soil, keep the temperature at about 20, and then germinate brightly. 2. Propagation by cuttings:

Select healthy, disease-free branches, cut off the leaves at the bottom of the branches and sterilize them, then cut the branches into the soil, keep the temperature between 15 and 20, and then water them appropriately. 3. Propagation by branches: Soil is cultivated at the root of the rose to promote its growth of new roots and filial piety stems, and then the new roots are cut and replanted.
