Cosmos is a very beautiful flower with vibrant colors and various shapes, making it an essential element in gardens. However, to have a cosmos garden, one must first learn how to plant cosmos. This article will introduce you to how to plant cosmos from the perspective of cosmos seed germination.
Selecting quality cosmos seeds
Before planting cosmos, you should first choose high-quality cosmos seeds to ensure good blooming period and quality later. Good seeds typically appear bright, uniform in size, without cracks or insect damage.
Preparing fertile soil
Cosmos prefers fertile soil, so before starting to plant, you need to select fertile, well-draining soil and add sufficient organic fertilizer and mineral elements to provide adequate nutrition for the cosmos.
Processing cosmos seeds
Before planting cosmos, you can soak the cosmos seeds in warm water for 4-6 hours to promote germination. During soaking, pay attention to avoiding water that is too hot or too cold, as well as prolonged soaking.
Sowing
Sow the processed cosmos seeds evenly on the soil surface, gently press the soil, and keep the soil moist. You can usually cover with a layer of fine sand or mint grass to maintain humidity and temperature.
Maintaining appropriate moisture
During the germination period of cosmos seeds, you need to keep the soil moist, but also avoid overwatering to prevent disease and death. You can use a sprayer or towel to gently wipe the soil surface to maintain moisture.
Choosing a suitable environment
Cosmos prefers a sunny, warm climate with good ventilation. During the germination period, you need to choose an appropriate location for planting and avoid excessive sunlight and low temperatures.
Controlling density
When sowing, pay attention to the distance between cosmos plants to avoid overcrowding which affects growth. Generally, the spacing between cosmos should be maintained at around 5-10 cm.
Timely pruning
After cosmos germinates, you need to prune timely to promote its growth and development. You can trim some overly dense seedlings and leave the healthier ones.
Proper watering
During the growth of cosmos, you need to water regularly and maintain appropriate moisture. But also pay attention to avoid overwatering to prevent root suffocation and disease.
Weeding promptly
During the growth and development of cosmos, you need to remove weeds and other unwanted plants in a timely manner and maintain cleanliness around the plants.
Fertilization
During the growth period of cosmos, appropriately applying nutrients such as phosphorus, nitrogen, and potassium can promote growth and extend the blooming period.
Pest and disease control
During the growth of cosmos, pay attention to pest and disease prevention. You can use biological pesticides or physical control methods and avoid chemical pesticides.
Paying attention to the blooming period
Cosmos generally starts blooming about 3-4 months after sowing. Pay attention to trimming wilted flowers in time and keeping the soil moist to extend the blooming period.
Harvesting and storage
After cosmos blooms, you can harvest and store them in a timely manner. You can dry them and store them in a dry, ventilated environment to maintain their quality and nutrition.
Cosmos is a beautiful flower. Growing cosmos requires patience and care, but by mastering the correct planting methods, you can surely have a beautiful cosmos garden.
