The correct cultivation method for coleus and care precautions
We know that coleus has many functions, and ornamental value is one of them. If you want to make coleus more beautiful, you need to master scientific planting methods. How can you grow coleus? Let's take a look at the propagation methods and precautions for coleus. Before cultivating coleus, you should understand its growth habits. Coleus is a plant that likes warm and humid environments. It is highly adaptable, tolerates abundant sunlight, but also has a certain degree of shade tolerance. When the winter temperature is not lower than 10 degrees, it can overwinter smoothly.
1. The most suitable soil: Coleus can adapt to various soil environments, such as acidic and alkaline, but its most suitable soil is fertile, loose, well-drained, humus-rich acidic soil, so garden soil, rotted leaf soil and river sand are the best.
2. The most suitable lighting: Because the ornamental value of coleus mainly comes from its leaves, if the leaves are bright, the ornamental value will be very high, while if the leaves are dull, the coleus will not be so beautiful. If the leaves are bright, it will need appropriate lighting. Its most suitable lighting condition is soft and sufficient. Coleus needs to avoid direct sunlight in summer, while also paying attention to the environment.
3. The most suitable temperature: Coleus likes a warm environment. The most suitable growth temperature for coleus is 18-25 degrees. In winter it should be kept above 10 degrees. If the temperature is too low, the leaves will turn yellow. If the temperature is 5 degrees, the plant will freeze to death.
4. The most reasonable watering: Coleus is a plant with high water demand. Lack of water will cause coleus to grow slowly, and the leaves will not be glossy. How do you cultivate coleus in terms of watering? Therefore, properly watering the soil is very important to ensure the soil is moist and create a humid environment.
5. The most scientific fertilizing: In the cultivation methods and precautions for coleus, its demand for fertilizer is not high, but ensuring the nutrients needed for its growth is more important, so during planting it is necessary to apply base fertilizer to the bottom of the soil. However, apply nitrogen fertilizer once or twice a month to promote leaf growth.
