How do longevity flowers reproduce? The propagation method of longevity flowers

Longevity flowers can take the way of branch cuttings, and cut strong branches to dry the wound before cuttings.

Longevity flowers should be cut in a warm environment, the ambient temperature is too high or too low is not good for rooting, should not be cuttings. The climate is suitable in spring and autumn, and the longevity flowers grow vigorously at this time, and the annual March-May and August-September are good times for cuttings, and the survival rate of cuttings is high. In order to increase the survival rate of cuttings, it is necessary to avoid rainy days.

The plant height of the longevity flower is 10-30 cm. The stems are erect. The leaves are opposite, elliptic, with blunt teeth.

polyumbel inflorescence; The florets are orange-red to crimson. Flowering period from February to May. The leaves are dense and green, and they bloom near Christmas, clustered in clusters, and are rich in flowers, making them a lovely indoor potted flower.

This flower was introduced to Europe by the German Potsdam from southern Africa.

Longevity flowers, also known as longevity flowers, dwarf cabbage, and Christmas cabbage, are perennial evergreen, fleshy and pulpy flowers of the Sedum family. Due to the relatively long flowering period, the natural flowering period usually starts in late December and can last until early May of the following year, hence the name longevity flower.

Longevity flowers are more likely to be propagated by vegetative propagation, and tissue culture is used to propagate in addition to cuttings. There are two ways to take cuttings: leaf cuttings and apical bud cuttings. Generally, leaf cuttings and tissue culture are mostly used for the production of female seedlings; Apical bud cuttings are mostly used in potted flower production.

Potted flower production generally takes rootless cuttings directly into the pots to be planted at the end, so the cultivation substrate and the cuttings substrate are the same, mixed with peat, perlite in the ratio of 7 3, and the pH value of the substrate is adjusted to between. Producers can adjust the proportion according to the water quality, production varieties, and production seasons, or add new soilless substrates such as vermiculite and sand to become a substrate with good drainage and moderate nutrient content.

1. Leaf cuttings. Remove the whole leaf as large as possible, place it in a cool place to dry the wound, and after a few hours, insert the petiole completely into the moist substrate, or if the petiole is too short, you can also insert part of the leaf into the substrate to replace the short petiole. At this stage, it should not be too wet, so as not to cause disease and rot of the leaves.

After cuttings, place them in a slightly weaker place in sunlight and keep the temperature between 20 and 25. After 3 to 4 weeks, the root system begins to build, at which point it can be placed in full sunlight conditions and a low concentration of fertilizer can be applied. After 7 to 10 weeks, the callus can be seen, and when the seedlings reach 15 20 cm, they can be planted separately from the leaves, and the leaves can continue to produce seedlings.

The separated seedlings can be used as mother seedlings for the production of rootless cuttings.

2. Apical bud cuttings. The prepared shoot top bud is used as a cutting, directly inserted into the pot with the substrate, the substrate is kept moist, the light intensity should not be too strong, the temperature is kept between 20 and 25, and it can take root in about 2 3 weeks, and then it can enter the production period management. Apical bud cuttings are generally used in potted flower production Note:

Kalancho is a typical long-day flowering plant, and the sunshine time must be longer than an hour during cuttings propagation, and the light must be supplemented during cuttings propagation in winter.

There are many propagation methods for longevity flowers, usually most of them are propagated by cuttings with the branches of longevity flowers, or their seeds can be soaked for 6 hours for sowing and propagation, and the leaves of longevity flowers close to the roots are cut off, and then inserted into sandy soil for leaf cuttings propagation, or plants and branches can be inserted into water for hydroponic propagation of longevity flowers.

Longevity flowers in the spring of May and June every year, or in the autumn of September and October, can be pruned in the process, select 5 6cm shoots for cuttings, need to place the shoots in the shade for 2 3 days, and then insert the branches into the sandy soil, water the sandy soil every day, keep it moist and control the temperature at 15 20, about a month will germinate.

You can buy excellent seeds of longevity flowers in the market, soak their seeds in clean water for 6 hours to make their seeds germinate better, and then sow the seeds into the prepared saprophylly sandy soil, and water the soil and cover it with plastic film, so that its seeds can germinate better in the potting soil.

In fact, there are many ways to propagate longevity flowers, usually you can also cut off the hypertrophic leaves close to the roots of longevity flowers, you need to place them in a cool and dry place for 30 60 minutes, obliquely inserted or spread on the sand, keep the sand slightly wet, you can use plastic film to keep it warm and moist, put it in a ventilated and sunny place, and wait for about a month to take root.

Longevity flowers can also be dug out of the soil, the roots are cleaned with water, if you find rotten roots, you need to cut them off, and put them in a cool place for a day, and then put them in a container with water for hydroponics, you can also use longevity branches to insert them into the water, change the water every other week, and wait for the branches of longevity flowers to take root.
