Cosmos Toppling and Heart Picking Diagram

Share cosmos topping and heart picking diagram and detailed pruning steps of green plants and flower introduction. Next, the editor will introduce it to everyone.

The flower to be introduced today is cosmos, also known as gesang flower. Recently, we will introduce a flower for spring sowing every day, hoping to relax everyone by learning about flower cultivation knowledge.

Introduction to Cosmos:

Cosmos is an annual herbaceous plant. Many people say it is a perennial plant, but the editor wants to correct it. After the cosmos flowers fade, the seeds can fall to the ground and reproduce themselves. If the temperature is suitable, they can be sown all year round, which can create an illusion that it is a perennial plant. Its flower colors are very rich, commonly pink, fuchsia, white, etc., and the flowers are very beautiful when they bloom. They are suitable for large-scale planting in gardens and for family potted care.

Growth Habits:

Cosmos is adaptable, prefers a sunny, cool, and ventilated growing environment, and is afraid of extreme heat and cold. It is drought-resistant and dislikes waterlogging. It can grow well in poor soil, but it is not tolerant to fertile soil. If the soil has a high humus content, cosmos will produce fewer flowers and the branches will grow excessively. Therefore, for family potted cultivation, it is best to use a loose, breathable, and well-draining matrix.

After briefly understanding cosmos, let's move on to the main topic to introduce the propagation methods and maintenance skills of cosmos:

I. Propagation Methods

There are mainly two methods of cosmos propagation: cutting propagation and sowing propagation. However, since it will produce seeds after the flowering period and the seeds have strong self-propagation ability, they can grow on their own when they fall into the soil, so we usually propagate it by sowing, which is simple and yields a large amount.

Of course, we need to buy flower seeds to sow at the beginning. Don't worry about fake seeds, cosmos seeds are very cheap, and the editor bought 500 seeds for less than 5 yuan, which won't be used if not planted in the ground.

[Sowing Time]

The sowing time for cosmos is mainly in the upper and middle part of spring every year, and it can be sown all year round in places with a constant temperature of around 20 degrees. Generally, it can start next month and should not exceed the end of April. As long as the temperature is around 10-25 degrees, it can germinate in 7-10 days and bloom in about 40 days.

[Soil Matrix]

Cosmos is a very easy-to-grow flower because it does not tolerate fertile soil. Therefore, you cannot use fertile soil like other flowers. For those with a courtyard, just dig the soil deeply in a high, sunny, and windward place and mix it with coarse river sand. For potted plants, you can use a large shallow pot with common garden soil mixed with river sand or perlite. The editor used a 34 cm diameter, 20 cm deep pot.

[Sowing Method]

Although cosmos does not like fertile soil, it has high requirements for soil water permeability, so the soil must be loose and well-draining, and drainage materials such as ceramic stones, broken bricks, broken tiles, hard foam, and broken pots must be placed at the bottom of the pot when planting.

After laying the drainage layer, fill the pot with soil matrix 9/10 full, gently shake the pot to make the soil compact, and then evenly sow the seeds on the soil, keeping the spacing. Sprinkle fine sand on the surface of the seeds, with a thickness of no more than 1 cm. If sowing directly in the ground, just sprinkle the seeds on the flattened soil and cover them with fine soil evenly.

After sowing, you can water the soil evenly with a fine stream of water and wait for the seeds to germinate. For potted plants, move the pot to a ventilated and shady place temporarily, and at a temperature of around 20 degrees, the seeds will germinate in about 7-10 days. However, make sure to keep the surface of the soil matrix moist during these days. After germination, move it to a place with scattered light and ventilation for maintenance.

Some flower friends may ask whether cosmos seeds need to be germinated before sowing? Here, the editor of Green Plant Enthusiast Network wants to tell you that cosmos seeds have a very high germination rate, after all, it is a flower with high self-propagation ability, so even if you sow directly without germination, it still has a high germination rate.

[Thinning and Transplanting]

The editor of Green Plant Enthusiast Network planted about 30 seeds in a pot with a diameter of 34 cm and then thinned and transplanted when the seedlings grew to about 5 cm in height. Just carefully dig out the dense seedlings and replant them in other pots. It is recommended to stop watering 2 days before digging the seedlings to make the soil slightly moist, so as not to cause bare roots during digging. Make sure to transplant with the original soil to increase the survival rate! After transplanting, water the roots and let them grow in a well-ventilated and shady environment for a few days, then move them to a sunny place for maintenance.

II. Maintenance Skills

[Water and Fertilizer Management]

Cosmos is drought-resistant and dislikes moisture and fertilizer. Yes, you read it right, cosmos is so individualistic. It is common to see drought-resistant and moisture-intolerant plants, but it is rare not to need fertilizer at all, which is why the editor of Green Plant Enthusiast Network says cosmos is a very easy-to-grow flower.

Generally, cosmos only requires the soil matrix not to be dry during the period before germination. After germination, you can add water when the soil is dry. It is a drought-loving flower, so you don't need to water it every day and should not cause waterlogging. Just keep the soil slightly moist. Only in high summer temperatures is it necessary to keep the soil moist, while other seasons are suitable for slightly dry maintenance.

Fertilizing is even more worry-free. Those familiar with the editor of Green Plant Enthusiast Network know that every time the editor talks about soil configuration, he mentions adding a small amount of base fertilizer. However, today the editor did not mention it because cosmos flowers less when the soil is fertile and more when it is poor. Therefore, no base fertilizer is needed when planting.

Just add a diluted 1000-1200 times mature organic fertilizer or a balanced organic nutrient solution 10 days after pinching and hearting. Appropriate fertilization after pinching can promote the faster growth and strengthening of lateral branches, early pinching of lateral branches, and increase the number of flowers.
