Cosmos watering: avoid waterlogging; fertilize with light doses and frequent applications

Cosmos is a flowering plant native to the Americas, and many people in China grow cosmos, but there are many things to pay attention to if you want to grow it well, among which watering and fertilizing are the most important. So how do you water and fertilize cosmos? Below, the editor will walk you through it.

1. How to water cosmos: water along the edge of the pot

As for how to water cosmos, the method is actually very simple. When watering it, we can pour water into the soil along the edge of the pot, and stop watering once the soil has a certain degree of moisture. Remember, never let water accumulate, otherwise the roots will rot.

1. Watering at planting: water thoroughly

Before planting cosmos, we need to water the soil thoroughly, or after planting, cover the seeds with 1-2 cm of soil, then soak the pot in water up to one-third of its height, letting water enter through the small holes at the bottom of the pot, and take the pot out once the soil becomes moist.

2. Watering at the seedling stage: control the amount of water

After cosmos sprouts, we should keep the soil at a certain level of moisture, which helps its growth. When the climate is relatively dry, we can appropriately increase the watering frequency to prevent the soil from drying out, but when watering we must pay attention to controlling the amount of water. Remember not to cause water accumulation, otherwise root rot is very likely to occur.

3. Watering during the growing period: keep the soil moist

After entering the growing period, cosmos has a great demand for water. It is best to keep the surface layer of the soil moist at all times. If it is too dry, the soil will crack, so everyone should pay attention to this. Water is still very important for it.

2. How to fertilize cosmos: light doses and frequent applications

When it comes to how to fertilize cosmos, we need to pay attention to a few points. First, when fertilizing, the fertilizer must not be applied onto the plant, otherwise it can easily burn the plant. Generally, it is enough to apply it into the potting soil, and before fertilizing, the fertilizer needs to be diluted with water first so that it can be absorbed better. If concentrated fertilizer is applied directly, it can easily burn the plant.

1. Fertilizing before planting: apply base fertilizer

Before planting cosmos, we can first apply an appropriate amount of base fertilizer into the soil, which allows the seeds to sprout faster. Also, after applying base fertilizer, there is no need to fertilize again after entering the growing period. If no base fertilizer was applied before planting, then regular fertilization is needed after entering the growing period.

2. Fertilizing during the growing period: fertilize once every 10 days

If no base fertilizer was applied to the soil before planting, then after entering the growing period we need to fertilize it regularly. Generally, fertilizing once every 10 days is enough. Do not fertilize too much, otherwise it can easily cause excessive vegetative growth, which will affect the number of flowers. Everyone should remember this.

3. Precautions for fertilizing: avoid fertilizing at high temperatures

When fertilizing cosmos, if the ambient temperature is relatively high, it is best to stop fertilizing. In normal fertilization, we should maintain a balance of nutrients and avoid the phenomena of excessive fertilizer and unbalanced fertilizer. When fertilizing, be careful that the fertilizer is not too close to the roots, otherwise it can easily burn the roots. Fertilizing can be done together with watering, but the amount must be controlled.

How do you fertilize cosmos?

Fertilizing time:

The best time to plant cosmos is spring, and the best time to fertilize is also spring.

Fertilizing at planting:

If base fertilizer has already been applied before planting, there is no need to fertilize during the growing period. Conversely, if no fertilizer is applied before planting, fertilization must be done during the growing period.

Routine fertilizing:

If no base fertilizer has been applied, an appropriate amount of fertilizer should be applied during the growing period. Under normal circumstances, fertilizing once every 10 days is fine. Fertilizer must not be excessive, otherwise it can easily cause the branches and leaves of cosmos to grow excessively, which will directly affect the number of flowers.

Fertilizing precautions:

1. In an environment with excessively high temperatures, or in midsummer, do not fertilize anymore.

2. When fertilizing cosmos, the nutrients in the fertilizer should be balanced, and the phenomena of excessive fertilizer and unbalanced fertilizer should not occur.

3. When fertilizing, avoid having the fertilizer too close to the plant roots, so as not to burn the roots.

4. Topdressing can be done during the seedling stage, but be sure to pay attention to the balance of fertilizer nutrients, and at the same time do not apply excessive fertilizer.

5. Fertilizing can be done together with watering. But water accumulation must never occur.

Friends can also apply topdressing according to their own actual situation when fertilizing, but the amount of fertilizer and the balance of nutrients must be well controlled. In fact, planting and growing cosmos is very easy. It is very suitable for beginners who love flowers but do not dare to grow them. At the same time, its ornamental value is also very high. Beginners might as well start by growing cosmos.

How to grow cosmos: cosmos cultivation methods and precautions / sufficient sunlight

Cosmos is a plant with high ornamental value, and it can be seen in many regions of China. There are many people in China who grow it, but there are many things to pay attention to if you want to grow it well. So how do you grow cosmos? What are the cultivation methods and precautions for cosmos? Below, the editor will walk you through it.

1. How to grow cosmos: understand its habits

To know how to grow cosmos, we first need to understand its growth habits. Cosmos is a light-loving plant, so when growing it we should maintain sufficient light. In addition, watering, fertilizing and other aspects also need attention. The specific details are introduced below, so let us continue reading.

2. Cosmos cultivation methods and precautions

1. Soil selection: good drainage is required

Among the cultivation methods and precautions for cosmos, choosing soil is the first step and the step that lays the foundation. Only by choosing suitable soil can cosmos grow more vigorously. Cosmos prefers to grow in loose sandy soil, which has good drainage and does not easily accumulate water.

Precautions: The soil for cosmos should not be too fertile either, otherwise it will have a certain impact on its growth. Generally, soil with a certain degree of looseness is enough.

2. Fertilizing requirements: avoid heavy fertilizer

Cosmos does not have a great demand for fertilizer during its growth process. If base fertilizer was applied to the soil when we planted it, then there is no need to fertilize after entering the growing period, because if too much fertilizer is applied, the sap will cause excessive vegetative growth, thereby reducing the number of flowers.

Precautions: If we apply base fertilizer into the soil before planting, the fertilizer must first be diluted with water so that it can be absorbed, because this plant is rather afraid of heavy fertilizer.

3. Watering requirements: a small amount but frequent watering

Among the cultivation methods and precautions for cosmos, watering is a point that requires relatively more attention. This plant prefers water. If the weather is dry, it should be watered 2-3 times a day. When the climate is suitable, watering once every 1-2 days is enough.

Precautions: When watering cosmos, remember to water a small amount but frequently, and just keep the soil at a certain level of moisture. Never water too much, otherwise if water accumulates, it can easily cause the roots of cosmos to rot.

4. Light requirements: pay attention to shading in summer

Cosmos prefers light, but it is not tolerant of strong light. If the sunlight in spring and autumn is relatively suitable, we can keep it outdoors to receive light for a long time, but when the sunlight is too strong in summer, shading is still needed.

Precautions: In summer, we can move it indoors to a semi-shaded place to grow it, which will not affect its growth. Winter is the opposite of summer. Normally we should grow it indoors, and when the temperature rises at noon, just move it outdoors to receive 2-3 hours of light.

5. Pests and diseases: prevent and control them promptly

During the growth process of cosmos, if we do not care for it properly, problems such as pests and diseases can easily occur. Such problems are extremely harmful to the plant, not only affecting its ornamental value, but in severe cases also causing cosmos to dry up and die.

Precautions: When problems such as pests and diseases occur, we must deal with them promptly. If the time is dragged out, it will be difficult to cure them completely. For specific prevention and control methods, everyone can refer to the article on pest and disease control for cosmos. The editor will not introduce too much here.
