How to propagate dahlia, the method of propagation / cutting / ramet / sowing of dahlia

Dahlia is a common plant in people's life, and many people choose to breed it at home. As more and more people breed it, many people are more concerned about its reproduction. About how to reproduce dahlias, what are the breeding methods of dahlias? Next, the editor will take you to learn about it.

2. Propagation methods of Dahlia

1. Cuttage propagation

Cutting time: cutting is one of the most common propagation methods of Dahlia, which can be carried out in spring, summer and autumn, but the most suitable time is from March to April, when the survival rate of cutting will be a little higher.

Cutting method: when cutting, the cuttage length we choose had better be about 8cm, the container caliber of cutting is better than 25cm, and the soil should be watered first when cutting, so that the cuttings will not be damaged in the process of cutting because of the drying of potted soil. Generally, the cuttings can take root in 2-3 weeks after successful cutting.

two。 Sowing and reproduction

Sowing time: the time of sowing and propagation is similar to that of cuttings, which is generally the best around April. This is the most suitable environment for the growth of dahlias, and the survival rate is relatively high, so the choice of breeding time is also a more important point.

Cutting method: when sowing, we can sprinkle the seeds evenly on the soil surface, and then cover it with a layer of soil, the thickness is about 2cm, after the completion of the need for watering, watering is best to use a spray can to spray, because the dahlia seeds are smaller, if the direct watering will be easy to wash away the seeds. After watering, seedlings can basically emerge in about 7 days.

3. Ramet propagation

The time of ramet propagation is generally about 3-4 months, when we separate the mother plant from the flowerpot, and then use scissors to cut off the underground stems connected between the leaves to plant separately, generally can be divided into about 2-3 plants, after the split on the normal planting on it.

Cutting Propagation methods of Dahlia

Dahlia is one of the most famous flower varieties in the world, and there are more than 30,000 dahlias. The general sowing and planting methods are applicable to dahlias. In fact, dahlias can also be propagated by cutting. The editor will introduce to you the matters needing attention in cutting propagation of dahlias.

Dahlia

Dahlia cuttings can be used for terminal bud, axillary bud and foot bud in all parts of the plant, but the foot bud is the best. The cutting time is from early spring to summer and autumn, and the survival rate is the highest in March and April. The cuttings can take root in about 2 weeks (but there are also some flower friends who have not taken root for 2 months, but the leaves have grown out). In order to improve the survival rate of cuttings, the roots were placed in the greenhouse before cutting. when the temperature was kept above 15 ℃, it was easy to lose all Q, and the cuttings were cut when the buds 6~10cm, that is, when the foot buds grew 2 true leaves.

There are also some flower friends who have done water cuttings and use vermiculite as substrate cuttings, all of which can be successfully cut (remember not to bask in the hot sun). After the cuttings survive, you can consider topping at 15cm, which can dwarf the Dahlia plant and have many flowers.

The reason why many flower lovers try to cut dahlias is that the stems of dahlias are empty and brittle and easy to be broken by the wind, so they should be supported by bamboo planting in time, which can also avoid the bending of branches and improve the ornamental value of potted plants. When the plant is more than 30 cm tall, a small bamboo should be inserted next to each branch and tied with hemp skin (or string); as the plant grows taller and taller, a longer bamboo should be replaced in time, and the final bamboo should be placed on the lower part of the bud.

What are the propagation methods of dahlia

Dahlia, also known as passionflower and dahlia, is a perennial herb of the genus Dahlia in Compositae. Originated in Mexico, it is now planted all over the world, with more than 30,000 varieties, which is one of the most famous flowers in the world. The propagation method of Dahlia is mainly cutting and root division, and sowing is mainly used in breeding.

What are the propagation methods of dahlia

(1) cutting

Softwood cuttings are usually carried out from March to May. Root tubers are placed in hotbeds or greenhouses in March. When the buds grow to 6-7 cm, two leaves are left behind and cuttings are cut. When the two axillary buds at the base grow to 6-7 cm, two more leaves are left to cut the cuttings, so that they can continue to be cut until May. The cuttings were cut into the sand nursery bed, then watered thoroughly, placed in the shade for several days, and gradually moved to the sun after a few days. The cuttings can blossom in the same year, and then go to the pot after the seedlings grow vigorously and the roots are developed.

(2) split root propagation

From March to April, the stored tubers are taken out and divided. Because dahlias only have stems in the rhizome, each tuber must have a budding rhizome. Sprouting can also be promoted before the ramet. The method is to arrange the tuber roots in the hotbed at a dense distance, then cover the soil and water them, give them a certain temperature, and divide each ramet after budding, so that each ramet has at least one bud, and after segmentation, the incision is smeared with plant ash to dry it so as not to rot, and then planted into the seedling bed.

(3) sowing

General dwarf potted varieties are propagated by sowing. Sow seeds in a breeding basin from March to April, cover the soil slightly after sowing, and use the soaking basin method to feed water to keep the basin soil moist. When the temperature was about 20 ℃, it germinated in about 7 days. The seedlings were transplanted into flowerpots or seedbeds when they were 5-8 cm high, and could blossom from August to October of that year.

Dahlia is the most widely cultivated flower in the world, and it is cultivated in many provinces and cities in China. Dahlia is a common ornamental flower with large shape and rich colors. Dahlia is rich in varieties, but the time of artificial breeding is not long, and cuttings and roots are often used to propagate. The editor has sorted out the breeding methods of dahlias for you in this article. I hope it will be helpful to you.
