Symbol and implication of cosmos flower language (the meaning of giving away cosmos as a representative)

introduction: cosmos, also known as broom plum, belongs to autumn British of Compositae, and is an annual or perennial herb. The reason why cosmos is called broom plum is that the leaves of cosmos are very similar to those of broom seedlings, and the flowers are as beautiful and fragrant as plum blossoms.

cosmos is brightly colored, pure and lovely, giving people a bright and pleasant feeling, and swaying, so the flower language of cosmos means "pure and affectionate".

Furthermore, cosmos has the functions of clearing away heat and resolving phlegm, enriching blood and dredging menstruation, so it is very popular among people. So what can we do to raise such a romantic cosmos? Let's talk about my point of view, hoping to help the needy flower friends.

how to breed cosmos?

1: method of sowing cosmos propagation

[1] time of sowing cosmos

We can sow cosmos in April-May in spring or July-August in summer, and the temperature is 2℃ when it germinates. Cosmos planted in spring tend to have lush leaves and few flowers. The cosmos sown in summer is short, neat and full of flowers. This is because the temperature is lower in spring, so the emergence and growth will be slower.

[2] Sowing cosmos

When we sow cosmos, we can sow it in flowerpots, and the soil can be mixed with humus soil and sand. This is the way to do it. Put some mixed soil of humus soil and sand in the flowerpot, then spread the seeds of cosmos evenly, and then cover it with 2 ~ 3 cm of fine soil. After spraying water with a watering can, put it in the sun, and pay attention to spraying water frequently to keep the soil moist. Under normal circumstances, seedlings can emerge in 7 ~ 1 days. When the cosmos grows to 2-3 leaves, we can carry out thinning for cosmos. The principle of thinning is to "remove the weak and keep the strong", and the spacing is generally 4-6 cm, which is convenient for transplanting with soil balls when transplanting in the pot. Then when the cosmos grows to 5 ~ 6 cm, it can be transplanted into the pot.

2: cutting cosmos

We can cut cosmos from August to September. When cutting, we can cut strong branches of cosmos from the nodes, cut them into sandy loam, put them in a cool and ventilated place, and take root in 15 to 2 days, keeping the soil moist in the middle.

how to transplant a potted cosmos?

1: Choose a flowerpot

When we cultivate cosmos in a flowerpot, we can decide the size of the flowerpot according to the number of cosmos cultivated in the flowerpot. Generally, we can plant 3-5 plants in one flowerpot. Choosing flowerpots is best to choose clay pots or earthen pots with good drainage and air permeability.

two: choose the right soil

cosmos has good adaptability, but prefers sandy soil with fertility, loose soil, rich humus and smooth drainage. When we cultivate, we can mix peat soil, humus soil and less coarse sand.

3: Transplanting cosmos in the upper pot

When we are ready to transplant, water the cosmos seedlings in advance, which is convenient for us to transplant with soil balls. Spread a thicker window screen at the bottom of the flowerpot, which can prevent the loss of soil and fertilizer. Put some finger-belly-sized hard plastic film on it, which can play the role of smooth drainage. Then put a layer of decomposed manure. Put the soil we have prepared on it, then put the cosmos with soil balls in the middle of the flowerpot, then bury the soil and compact it gently, then water it, put it in a cool place to slow down the seedlings, and then maintain it normally. How to maintain and manage the cosmos after it has been put into the basin?

1: Pruning management

After we transplant the cosmos into the pot, when the cosmos grows to 8-1 leaves, we will pick the heart and top it, so that more lateral branches can grow and then more flowers will bloom. If the heart is picked too early, cosmos will not bloom easily.

and because cosmos grows rapidly, we can pluck the hearts of cosmos many times, so that cosmos not only grows short, but also blooms more. When the seeds of cosmos are ripe, they are easy to fall off, so we can harvest them in the early morning.

2: temperature management

cosmos likes warmth, neither cold nor extreme heat, and the suitable temperature for growth is between 18℃ and 24℃. When the temperature is too high, the leaves of cosmos will grow vigorously and the flowering will decrease. When the temperature is below 1℃, it will be prone to decay.

three: lighting management

cosmos likes sunny environment. If the light is insufficient, cosmos will grow in vain and its flowers will not be bright.

iv: watering management

cosmos is drought-resistant and afraid of water accumulation, so it needs proper watering. Generally, when growing, it is good to keep the soil moist. In spring and autumn, after the cosmos is transplanted into the pot, we can water the cosmos every 2-3 days to make the pot soil moist. When it is hot in summer, we can water cosmos once every 1-2 days. When watering, it is best to water it in the morning or evening. If the temperature is too high, we can spray water for cosmos to reduce the temperature, so that cosmos can grow faster. When it rains in summer, we can put the cosmos in a shelter. If it rains heavily, we can drain the water from the cosmos flowerpot.

five: fertilization management

cosmos is more barren-tolerant. If the base fertilizer is applied, it can be used without fertilization in the later stage. Otherwise, if there is too much fertilizer and water, it will lead to the situation that the cosmos will grow in vain, and the flowering will become scarce.

However, before the cosmos blooms, we can apply thin phosphorus and potassium fertilizers, which will not only make the stems of the cosmos stronger, but also make the flowers bloom more brightly, and also play a role in preventing diseases of the cosmos.

VI. Pest management

[1] Powdery mildew

When powdery mildew appears in cosmos, the tender leaves, stems and buds of cosmos will appear gray powder, and then the leaves will become distorted and the flowers will not bloom normally. Seriously, it will also lead to the death of cosmos.

solution: we can first take off the diseased leaves and burn them, and then spray 15% triadimefon 15 times for treatment. Also, when raising cosmos, we should apply thin phosphorus and potassium fertilizer to increase the resistance of cosmos. Then do a good job in ventilation management, and don't let cosmos grow in a high temperature and high humidity environment.

[2] leaf spot disease

When there is leaf spot disease in cosmos, there will be brown spots on the leaves, and then the whole leaves will wither, which will seriously cause cosmos to wither and die.

solution: we can take off the leaves and burn them when cosmos gets sick, and then spray 5% mop wettable powder 5 times to prevent and treat them.

[3] Aphids and scarabs

The main pests of cosmos are aphids and scarabs, and we can treat them by spraying 25 times of 1% insecticide EC. Also, when it is dry and hot in summer, it is necessary to water it properly to prevent the emergence of red spiders.

To sum up

Persian chrysanthemum, which means "pure and affectionate", can be propagated by sowing in April-May in spring or July-August in summer, when the germination temperature is about 2℃. Cuttings can be carried out from August to September.

When the transplanted cosmos grows to 8-1 leaves, we can pick the core and top it, and then we can pick the core for many times, which will not only make the cosmos plant short, but also grow more lateral branches and blossom more.

Furthermore, we can pass the temperature of 18 ~ 24℃; Sufficient light; Water the soil wet during the growing period; The method of applying thin phosphorus and potassium fertilizer before flowering; And the prevention and control of pests and diseases, you can make the flowers of cosmos beautiful and beautiful.
