How to grow Dianthus? The latest cultivation methods and precautions

Dianthus is a flowering plant with a wide variety of cultivars. Its flowers are quite distinctive, with the petal edges and the center of the flower differing in color, making them look extremely beautiful. Dianthus is planted on a large scale outdoors in China, and many people also grow it indoors. So how should Dianthus be grown? Follow the editor to take a look at the cultivation methods and precautions for Dianthus.

I. Cultivation methods

1. Soil

The growth and development of plants are inseparable from soil rich in nutrients. Dianthus has relatively high soil requirements, and only soil with good drainage and lush growth can support its growth. Therefore, it is recommended to choose a mixed soil of garden soil and humus soil. This kind of soil is not only rich in nutrients, but also allows Dianthus to absorb nutrients better.

2. Temperature

Dianthus is a plant that likes warmth and is not cold-tolerant. Its optimal growing temperature is 15-20 degrees. When the summer temperature is too high, it should be properly shaded and cooled. When the winter temperature is too low, it should be placed indoors for care, keeping the temperature at 10 degrees to prevent it from freezing to death.

3. Light

Dianthus likes light, and only then can Dianthus grow normally. In spring, autumn and winter, it can be placed in a sunny place for care. In summer, diffused light should be the main source, avoiding exposure to strong sunlight. When the summer temperature is too high, it should be properly cooled, and water can be sprayed around it.

4. Watering

Dianthus does not have high nutrient requirements. Keeping the moisture at an appropriate level is enough, and waterlogging must not occur in the potting soil. The frequency of watering should be determined by whether the soil is dry or wet. If it is too dry, water it appropriately and keep the soil moist. In most areas, Dianthus can bloom normally relying on natural rainfall, and cultivation is relatively simple.

5. Fertilizing

Dianthus does not have high fertilizer requirements. Applying farmyard manure or compound fertilizer once before sowing can meet the needs of the entire growth cycle. Use decomposed cake fertilizer or organic fertilizer, and remember to dilute it before each application, so it is easier for the plants to absorb.

II. Precautions

1. Keep sufficient light

When growing Dianthus, the daily light duration must not be less than 6 hours, and it is best to maintain 6-8 hours of light. In summer, the plant enters a semi-dormant state, so exposure to strong sunlight should be avoided and proper shading is needed. In addition, waterlogging at the bottom of the pot should be avoided, otherwise root rot is very likely.

2. Disease control

Dianthus is highly susceptible to rust disease. When the disease occurs, brown spots mainly appear on the leaves and stem tips in a speckled state. If not controlled in time, the leaves will gradually turn yellow and wither, and in severe cases cause death. So once discovered, promptly spray the leaves with carbendazim every 10 days, and they can return to normal in a short time.
