How to Care for Large Cuckoo Flowers
Sharing the experience of how to care for large cuckoo flowers and the related knowledge of flower cultivation, the site editor will introduce to the netizens next.
Cuckoo flowers, also known as Rhododendron simsii, belong to the Rhododendron genus of the Ericaceae family and are famous flowers in China. Cuckoo flowers have high medicinal value and can treat diseases such as kidney deficiency, irregular menstruation, and rheumatism. In addition, the bright colors of cuckoo flowers make them highly ornamental and are the city flowers of several cities, including Sanya, Hainan Province and Shenzhen, Guangdong Province. Next, let's introduce the cultivation methods of cuckoo flowers.
1. Soil
Cuckoo flowers need to grow in loose, fertile, well-ventilated, humus-rich acidic soil. Some varieties can grow in slightly alkaline soil; however, cuckoo flowers cannot grow in calcareous soil or in overly heavy clay soil.
2. Fertilization
Cuckoo flowers enjoy fertilizer. If you want the flowers to bloom more vigorously, you should fertilize them properly, providing sufficient nutrition to ensure the quality of flowering. Fertilization usually takes place after the end of flowering in late spring, with a frequency of about twice a month. In the spring and autumn growing seasons, you can also apply some diluted fertilizer water, about three times a month. Remember to apply thin fertilizer frequently, as excessive fertilization can burn the weaker roots.
3. Watering
Since the roots of cuckoo flowers are not particularly thick and strong, they are prone to waterlogging. When watering, always follow the principle of watering when dry and not watering when not dry. Avoid excessive watering that can lead to accumulated water in the pot. Apart from the hot summer days when it's usually watered once a day, other seasons can be watered every 2-3 days. In addition to using tap water, rainwater can also be used to water the plants, as the acidic rainwater can help improve the soil's pH value, promoting better growth of the cuckoo flowers.
4. Temperature
Cuckoo flowers prefer cool temperatures and are afraid of heat. The most suitable temperature range for the growth of cuckoo flowers is between 12-25 degrees Celsius. If the temperature exceeds 35 degrees Celsius in summer, the flowers will gradually enter a dormant period and stop growing, so it's important to ensure proper ventilation and cooling in the summer. In winter, it's best to keep them indoors, as temperatures below 0 degrees Celsius or frost can lead to plant death.
5. Light
Cuckoo flowers enjoy light but cannot tolerate direct sunlight. It's best to grow the potted plants in an environment with gentle, scattered light. In summer, it's important to provide shade for them, as direct sunlight can burn the leaves. Also, avoid placing them in a dark environment, as insufficient light can hinder photosynthesis, affecting plant growth and flowering.
6. Pruning
In addition to regularly pruning old, weak, and diseased branches and overly lush branches during spring and autumn, it's also necessary to remove some flower buds during the bud formation stage to ensure that nutrients are concentrated.
7. Potting
Cuckoo flowers need to be repotted regularly to prevent soil compaction and malnutrition. It's recommended to change the potting soil every 2-3 years, usually after the flowering period when the flowers have wilted. Be careful not to damage the roots during the process.
8. Diseases and Pests
Leaf spot, brown spot, and black spot diseases are the main diseases that affect the plants, with symptoms such as spots on the leaves, yellowing, withering, and falling off. The prevention and control methods include improving the lighting and ventilation conditions of the environment, increasing the content of nitrogen and phosphorus-potassium elements in the fertilizer, promptly pruning infected plants to prevent the spread, and using Bordeaux mixture or other effective chemicals to spray the plants.
