Canna lily, also known as evergreen, is a very common green plant. Its leaves are full and rich, with bright and beautiful colors, making it a favorite for home potted plants. How can we make our canna lilies grow healthily and vigorously? Let's find out in detail.
1. Understanding the basic information of Canna lily
Canna lily is a perennial plant native to South Africa, belonging to the Geraniaceae family. Its leaves are heart-shaped or oval, and its flowers are funnel-shaped with a variety of bright colors. It prefers a warm and humid environment and is suitable for growing in semi-shaded places.
2. Choosing suitable soil and pots
In the process of care, the choice of soil and pots is very important. Canna lily likes a fertile, well-drained, and non-waterlogged environment. Therefore, we should choose loose, well-ventilated soil and add some small stones at the bottom to improve drainage.
3. Paying attention to suitable light and temperature
Canna lily likes a warm and humid environment and needs sufficient light for photosynthesis. However, it should be noted that strong summer sunlight can damage the leaves of canna lily, so it is necessary to block the strong sunlight appropriately. At the same time, canna lily also has requirements for temperature, and it grows best at 20°C-25°C.
4. Regular watering and fertilizing
Canna lily needs regular watering and fertilizing to maintain its healthy growth. In summer, the soil needs to be kept moist, but be careful not to overwater to avoid waterlogging. In winter, the frequency of watering should be appropriately reduced. Fertilizer can be organic or compound fertilizer, applied once in spring and autumn respectively.
5. Paying attention to pest and disease control
Canna lily is susceptible to pests such as aphids, red spiders, and whiteflies, so we need to check regularly and take corresponding preventive and control measures. For example, you can use pesticides for spraying, or wash the leaves with soapy water.
6. Paying attention to repotting and pruning
Canna lily grows quickly and is prone to loose soil and tight roots. Therefore, it needs to be repotted regularly, and pruned before repotting to maintain its healthy growth. When pruning, we can appropriately trim some branches to promote new growth.
7. Paying attention to proper dormancy
Canna lily also needs a proper rest time, usually entering dormancy in winter every year. During the dormant period, we can appropriately reduce the frequency of watering and fertilizing, and place it in a relatively cool place.
8. Paying attention to preventing leaf curling
If the leaves of canna lily curl, it is likely caused by pests, diseases, or high temperature. Therefore, we need to check regularly and take corresponding measures. At the same time, we should also pay attention to controlling indoor temperature and humidity to avoid leaf curling.
9. Avoiding excessive disturbance
In the process of caring for canna lily, we should try to avoid excessive disturbance. Because excessive disturbance will affect the growth of canna lily, and may even lead to its death. Therefore, be as gentle as possible when repotting and pruning.
10. Paying attention to preventing root rot
The roots of canna lily are prone to rot, which is usually caused by overwatering. Therefore, we need to pay attention to controlling the frequency and amount of watering to ensure that the roots of canna lily are not overly moist.
11. Regularly cleaning up fallen leaves and dead branches
In the process of caring for canna lily, we should also regularly clean up fallen leaves and dead branches to keep it tidy and healthy. If fallen leaves and dead branches are not cleaned up in time, they can easily become a breeding ground for pests and diseases.
12. Appropriately strengthening light exposure
If canna lily grows slowly or its leaves turn yellow, it is likely due to lack of light. At this time, we can appropriately increase the light time or move it to a place with more sunlight.
13. Paying attention to avoiding excessive fertilization
Although fertilizing is one of the important measures to maintain the healthy growth of canna lily, excessive fertilization will also affect its growth. Therefore, it is necessary to control the frequency and amount of fertilization to avoid excessive fertilization.
14. Paying attention to preventing pollution from soot, dust, etc.
In the process of canna lily's growth, pay attention to avoid the impact of pollution such as soot and dust. Because these pollutants will make the leaves of canna lily dull, affecting the ornamental effect.
15.
In the process of caring for canna lily, we need to master some basic cultivation techniques, such as choosing suitable soil and pots, paying attention to suitable light and temperature, regular watering and fertilizing, etc. At the same time, we also need to pay attention to preventing and controlling pests and diseases, repotting and pruning, proper dormancy, etc., to ensure the healthy growth and ornamental effect of canna lily.
