How to propagate carnations? Introduction to common propagation methods

Carnation propagation is divided into two types: asexual propagation and sexual propagation. Sexual propagation often has a low seed-setting rate, the offspring from seed vary greatly in traits, and the seedlings grow slowly, so it is rarely used in production. Asexual propagation is widely used in production, mainly cutting propagation, which has the advantages of abundant cuttings, stable traits and quick results. Let's take a look together below!

Carnation seed propagation

The germination temperature for carnation seeds is best at around 20°C. They should be sown indoors in early spring or sown in the open field in September-October, and protected over winter, where the temperature must not be higher than 15°C or lower than 0°C. They can be potted up in spring.

Carnation layering propagation

Carnation layering is carried out in August-September. Select a long branch, cut open the bark on the part touching the ground with a knife, cover it with soil, and after 5 to 6 weeks it can take root and survive.

Carnation tissue culture

Carnation tissue culture propagation is an important means of producing virus-free plantlets and is widely used in cut flower production. Generally, shoot tips are used for virus-elimination culture and then mass-propagated.

Carnation cutting propagation

1. Cutting selection: Select plants that are free of pests and diseases, grow vigorously and have tight internodes, with 3~4 pairs of expanded leaves and 1 pair of unexpanded leaves, and the rate of cuttings bearing flower buds in the group is less than 10%.

2. Taking cuttings: The taking of cuttings is generally carried out at the same time as bud thinning of carnations. Cuttings should be taken according to standards. When taking cuttings, break off the shoots by hand rather than cutting with scissors, to avoid cross-infection by viruses. The base should carry a little cortex from the main stem, but the mother branch must not be damaged. Keep 4~5 leaves at the top of the cutting and remove all the rest. After arranging them into bundles, soak them in clean water for 30 minutes so the cuttings absorb enough water. The cut surface should be close to the internode, and they should be treated with growth regulators to increase the survival rate and the rate of plants ready for sale.

3. Cutting storage: Storing cuttings can greatly facilitate year-round seedling raising and year-round balanced flower supply, and allows batch operations to be carried out at one time, saving manpower and materials. The storage temperature is 1~2°C, and the smaller the fluctuation the better, preferably within ±1°C. Before storage, the cuttings should be slightly dehydrated, and they should be packaged in ultra-thin plastic film.

4. Cutting time: Generally, the hot summer months of July-August should be avoided. The cuttings are required to be of good quality, larger-particle perlite is used as the cutting medium, the water quality is good, and the cutting bed is a raised bench.

5. Cutting method: When cutting, inserting into the medium by 1 cm is appropriate; in summer, insert deeper, generally 1.5~2 cm. After cutting, spray enough water, and afterward keep it from being too wet to avoid root rot.

6. Cutting management: The cutting bed should have intermittent misting facilities, with the amount of mist controlled so that the leaves are just moist. If there is no misting measure, plastic film must be covered, and after 1 week switch to reed blinds, but do not shade too much, to prevent leggy growth. When the roots of the cuttings are 1 cm long, transplant them, taking care to damage the roots as little as possible.

How do carnations propagate? Carnation propagation methods

Carnation propagation methods generally include seed sowing, layering propagation, tissue culture and cutting propagation. These are introduced in detail below, in the hope of helping flower lovers who grow carnations to propagate them better.

Carnation propagation methods

The original name of the carnation (detailed introduction) is Xiangshizhu. The carnations we commonly see now are all cut flowers. Many netizens may be curious about how carnations are actually propagated. The editor will introduce the propagation methods of carnations for you; flower lovers who like carnations can also learn about them.

Carnation (detailed introduction)

First, there are two ways to plant carnations, one is asexual propagation and one is sexual propagation. If sexual propagation is chosen, the seed-setting rate is generally relatively low, and after developing offspring, the possibility of variation is relatively great, and the growth rate of the seedlings is also relatively slow. However, it also has advantages: the cuttings are abundant and the results are relatively quick.

Cutting propagation is another cultivation method. First, healthy growing plants need to be selected, then after avoiding midsummer, perlite is used as the mother medium for cutting, but the water quality must be relatively good. When taking cuttings, operate according to standards; scissors must not be used to cut, and the mother branch must not be damaged during the operation. After arranging them, they need to be soaked in clean water for 30 minutes, then stored. After storage, carry out cutting management, but ensure the plants have sufficient light. Whether potted or in other cultivation forms, the water quality should be strictly selected and treated.
