Propagation methods of Dahlia

1. Root-splitting propagation

In March and April of spring, take out the root, cut off the attached buds together, and plant them separately.

2. Cuttage propagation

From June to August, the lateral buds grew to 15 to 20 cm, and the lateral buds were cut and sown with cutting.

Seeds are propagated, seeds are harvested in autumn and sown from February to March of the following year. Now you know the breeding methods of dahlias, there are a variety of breeding methods, it seems that the vitality of dahlias is really strong! Well, that's all for dahlias.

Culture methods of Dahlia

Before talking about the cultivation methods of dahlias, we need to tell the flower friends that the pot cultivation of dahlias is difficult and difficult to take care of, so if you are potted dahlias, you need to play a hundred and twenty thousand spirit to learn the maintenance methods of dahlias.

In order to make it easier for flower lovers to understand the culture methods of dahlias, this article will talk about the cultivation of dahlias according to different steps, so that they can master more knowledge about dahlias as much as possible.

1. Conservation of the environment

Whether potted or planted on the ground, they all need to be maintained in a sunny environment and to be leeward, because the stem of Dahlia is relatively weak, easy to break, can not stand the strong wind, and should be slightly shaded when the sun is more poisonous in summer. If long-term maintenance in the environment of lack of light, the root system is weak, the leaves are thin and the stems are thin, the flowers are small and light, and even cannot blossom.

2. Soil selection.

Because dahlias like to be wet and afraid of waterlogging, fat and excess, the soil should be fertile and loose (in fact, most flowers and plants require fertile and loose soil).

3. Planting

Dahlia is a tuber plant with huge tuberous roots. in general, what flower friends buy is tuber roots. Planting is actually very simple. What you need to talk to you here is covering soil. Generally speaking, covering soil is about 3 centimeters. At the initial stage, it is less watered and drier. Wait for the bud and then water it step by step.

4. Watering

Although Dahlia likes wet but is afraid of waterlogging, it is also afraid of drought, and its roots are easy to rot if it is watered too much, but its leaves are large, grow luxuriantly, and need more water. If it is short of water and wilts, it can not replenish water in time, and after sunlight, the edges of the light leaves are scorched, and the heavy ones fall off, so the water permeability of the soil is very important, and it also needs flexible watering according to the soil moisture.

5. Fertilization

Once the dahlias bloom, they will continue to bloom, and the ones that bloom are getting smaller and smaller, and they need a lot of phosphorus and potassium fertilizer in the later stage, but dahlias are afraid of excessive fertilizer, so fertilization should be carried out in accordance with the principle of applying thin fertilizer and applying thin fertilizer every other week.

6. Maintenance measures of Dahlia in winter

(1) stop watering: stop watering immediately after the dahlias fade, forcing the stems of dahlias to go into dormancy.

(2) pruning thoroughly: when the stem of Dahlia is completely withered and yellow, cut off all the stems that are more than 6 cm above the ground. Prepare to enter the indoor storage.

(3) Storage conditions: the temperature in the storage room must be kept at 15 °C. And the storeroom must be dry and must not be watered during storage.

(4) Storage overwintering: it should also be noted that when digging up the root tuber, do not damage the root tuber as much as possible. If it is a potted plant, it is best not to take off the pot, wait until the pot soil is very dry and the outdoor temperature drops to 3 degrees Celsius, move people indoor to pile up for the winter.

If the winter temperature in the city is not suitable for the growth of dahlias, cut off the water and wither the leaves, dig up the root and plant it again in the following spring.

Propagation methods of Dahlia

Dahlia, also known as Dahlia, dicotyledonous class, Compositae. Because it is easy to survive, it is cultivated all over the world, and new varieties continue to appear. Because its stem is erect and multi-branched, stout, and the petals are in full bloom, the height can reach as high as 2 meters.

Although the living environment of dahlia is not high and easy to feed, if you want to produce a beautiful dahlia, you still need to make a reasonable allocation of its growth environment. Dahlia is a semi-light plant, the sun exposure should not be too strong, the irradiation time is about 8 hours, the seedlings should not be illuminated. Temperature requirements are not strict, below 35 degrees Celsius, more than 10 degrees Celsius can grow, but the blooming period is the cool autumn. The temperature is best around 20 degrees Celsius. Dahlias prefer water, but can not be too waterlogged, potted plants need to be watered regularly, but can not accumulate water. The best soil for planting is crisp sandy soil, which is the favorite of dahlias.

Dahlia propagation methods are generally divided into cutting and seed reproduction, general seed propagation before March, autumn harvest, adapt to the temperature of about 18 degrees Celsius, specific sowing needs to be changed according to the region and climate. In the seedling growth stage, water should be controlled, because water control can control the height of dahlias after seedling growth and regularly eliminate the accumulation in the pot. It is not suitable to spray a large amount of water in summer to reduce the surrounding temperature, otherwise it will cause wilting of dahlias or death due to too much water. After growing up, the flower buds should be fertilized, and the flower stalks should be supported by utensils.
