Symbolism and Meaning of Cosmos Flower Language
An introduction to the symbolism and meaning of cosmos flower language and the significance of giving cosmos as a gift in the aspect of green plants and flowers, which will certainly help you. Let's learn about it together!
导读：Cosmos, also known as sweepstakes, belongs to the asteraceae cosmos genus and is an annual or perennial herbaceous plant. Cosmos is called sweepstakes because its leaves resemble the leaves of sweepstakes, and the flowers are as bright and fragrant as plum blossoms.
The cosmos has bright colors, pure and lovely, giving a bright and pleasant feeling, and swaying gracefully. Therefore, the flower language of cosmos is "pure and flawless, and passionate."
Moreover, cosmos has the functions of clearing heat and phlegm, and invigorating the blood and dredging the meridians, so it is very popular among people. So how can we take care of such a romantic cosmos? The following article will discuss my views and I hope it helps flower lovers.
How to Propagate Cosmos?
One: Cosmos Seed Propagation Method
[1] Cosmos Sowing Time
We can sow cosmos from April to May in spring, or from July to August in summer, with a germination temperature of 20℃. Cosmos sown in spring often has lush leaves and few flowers. Cosmos sown in summer is short, neat, and has more flowers. This is because the temperature in spring is lower, so seedling emergence and growth are slower.
[2] Sowing Cosmos
When sowing cosmos, we can sow in flower pots. The soil can be mixed with decomposed leaf soil and sand. The method is as follows. Place some mixed soil of decomposed leaf soil and sand in the flower pot, then evenly sprinkle cosmos seeds, and cover with 2-3 centimeters of fine soil. After watering thoroughly with a spray bottle, place it in the sun. Pay attention to喷水 frequently to keep the soil moist. Generally, the seeds can germinate in 7-10 days. When the cosmos has 2-3 leaves, we can thin the cosmos seedlings. The principle of thinning is "remove the weak and leave the strong". Generally, the spacing is 4-6 centimeters, which is convenient for transplanting with a soil ball. Then, when the cosmos grows to 5-6 centimeters, it can be transplanted into a pot.
Two: Cutting Cosmos
We can cut cosmos from August to September. When cutting, we can cut 15 centimeters of strong cosmos branches from below the node, cut them into sandy loam soil, water thoroughly after planting, and place them in a shady and ventilated place. The roots can take 15-20 days, keeping the soil moist in between.
How to Transplant Cosmos into Pots?
One: Choosing a Pot
When growing cosmos in a pot, we can decide the size of the pot based on the number of cosmos plants. Generally, we can plant 3-5 cosmos plants in one pot. It is best to choose a clay pot or a tile pot with good drainage and ventilation.
Two: Choosing the Right Soil
Cosmos has good adaptability, but it prefers fertile, loose soil rich in humus and well-drained sandy soil. When cultivating, we can use a mixture of peat soil, decomposed leaf soil, and a small amount of coarse sand.
Three: Transplanting Cosmos into Pots
When we are ready to transplant, we should water the cosmos seedlings thoroughly in advance, which makes it easier for us to transplant with a soil ball. At the bottom of the pot, place a piece of thick window screen to prevent the loss of soil and fertilizer. Then place some small pieces of hard plastic film, which can facilitate smooth drainage. Then add a layer of decomposed manure. On top of that, place the prepared soil, then put the cosmos with a soil ball in the middle of the pot, cover the soil, gently compact it, water thoroughly after that, and place it in a shady place to slow down the seedlings before normal maintenance.

How to Care for Cosmos after Potting?
One: Pruning Management
After transplanting cosmos into pots, when cosmos grows to 8-10 leaves, we should pinch the top to encourage more lateral branches and more flowers. If pinching too early, cosmos may not bloom easily.
Also, because cosmos grows rapidly, we can pinch cosmos multiple times, which not only makes cosmos shorter but also blooms more. Cosmos seeds mature and easily fall off, so we can collect seeds in the early morning.
Two: Temperature Management
Cosmos prefers warm temperatures, is not cold-resistant, and not heat-resistant. The optimal growth temperature is between 18-24℃. When the temperature is too high, cosmos will have lush leaves and fewer flowers. When the temperature is below 10℃, it is prone to decline.
Three: Light Management
Cosmos prefers a sunny environment. If the light is insufficient, cosmos will grow tall and the flower color will not be bright.
Four: Watering Management
Cosmos is drought-resistant and afraid of waterlogging, so watering needs to be moderate. Generally, during the growing period, the potting soil should be moist. In spring and autumn, after transplanting cosmos into pots, we can water cosmos every 2-3 days to keep the potting soil moist. In summer, when it's hot, we can water cosmos every 1-2 days, preferably in the morning or evening. If the temperature is too high, we can spray water on cosmos to lower the temperature, allowing cosmos to grow faster. In summer, when it rains a lot, we can place cosmos in a rain shelter, and if it rains heavily, we can remove the accumulated water from the cosmos pot.
Five: Fertilization Management
Cosmos is relatively tolerant of poor fertility. If a base fertilizer is applied, no additional fertilization is needed later. Otherwise, too much fertilizer and water can cause cosmos to grow tall and fall over, and flowering will become sparse.
However, before cosmos blooms, we can apply a dilute phosphorus and potassium fertilizer, which not only makes the cosmos stem stronger but also makes the flowers more vibrant and can prevent cosmos from getting diseases.
