How to Care for Corn Poppy in Winter? A Detailed Guide to the Latest Care Methods
The corn poppy (Papaver rhoeas) is a herbaceous plant native to Europe. It is cultivated and commonly seen throughout China, and is an excellent ornamental plant. When the corn poppy blooms, its colors are rich, its petals are as thin as silk, smooth and flawless, and its corolla is as beautiful as red clouds. Its flowering period is very long. It can be grown in pots or used as a cut flower, and can likewise be planted in masses in flower beds and parks. The corn poppy is suited to growing in a well-ventilated environment with sufficient light. It is cold-tolerant but not heat-tolerant, and is suitable for sowing in spring, autumn, or early winter. Although the corn poppy is cold-tolerant, frost damage can still occur under extremely cold winter conditions. Below, Qinong Web introduces for everyone: winter care methods for the corn poppy.
1. Growth Habits
Before introducing the methods for the corn poppy to overwinter safely, we should first understand the living habits of the corn poppy. Only by understanding what kind of living environment the corn poppy likes can we provide it with the best care. The suitable temperature for the growth and development of the corn poppy is 5-25°C. In areas with high temperatures in spring and summer, the flowering period is shortened, and the temperature difference between day and night is large. Low nighttime temperatures are beneficial to growth and flowering. It grows well in high-altitude mountainous areas, and its flower colors are even more brilliant. Its lifespan is 3-5 years. It is cold-tolerant, afraid of summer heat, likes a sunny environment, and prefers well-drained, fertile sandy loam. It is not tolerant of transplanting and hates waterlogging.
2. Light
Most flowers need certain light conditions to bloom smoothly, and the corn poppy is no exception. The corn poppy likes light, and the growing period requires sufficient light, with at least 4 hours of direct sunlight every day. Light has a very large impact on the flowering period and the flowers. With sufficient light, the flowering period comes earlier, the flowers are larger, and the colors are more vivid. If the light is insufficient, the flowering period will be delayed, and otherwise the flowers that grow will also look malnourished.
3. Temperature
As mentioned earlier, the corn poppy is cold-tolerant but not heat-tolerant. The corn poppy is indeed a relatively cold-tolerant plant. It likes coolness and avoids high temperatures. In the south, there is no need to worry about frost damage at all. In the north, there is no need to worry if it is grown indoors. If grown outdoors, a layer of plastic film can be covered over it, and then removed in spring.
4. Water
The corn poppy is relatively tolerant of dryness and drought, but not of waterlogging. During the growth period, watering should not be excessive, and it is best to keep the soil moist. Unless it is very dry, there is no need to water. However, excessive drought will delay flowering and affect quality. In winter, water less; during the spring growing period, water more.
5. Fertilizing
Fertilizer is also one of the indispensable conditions for the corn poppy to grow well. Before the corn poppy blooms, dilute liquid fertilizer should be applied 1-2 times. After buds appear, spray the leaves with 0.1% potassium dihydrogen phosphate solution once every 3 days to force flowering. Fertilizing must not be excessive; otherwise, the plants will grow leggy, and if too tall, they will also easily lodge.
6. Pruning
Pruning the corn poppy mainly serves two purposes: first, for overall beauty and elegance, so excess branches and leaves are cut off; second, so that nutrients can be concentrated and not consumed too much by redundant parts, so the corn poppy needs pruning. If the faded flowers of the corn poppy are cut off in time when the flowers fade, preventing the faded flowers from setting seed, nutrients can be concentrated, and the later flowers can grow strong, thereby extending the flowering period.
The above are the overwintering tips related to the corn poppy prepared for everyone by Qinong Web. Besides being ornamental, the corn poppy is also a very good traditional Chinese medicine. The whole plant can be used as medicine. The corn poppy contains a variety of alkaloids and has effects such as relieving cough, stopping diarrhea, relieving pain, and calming. The corn poppy lives up to its name and is sought after by many people. Although the corn poppy belongs to the genus Papaver in the family Papaveraceae, it can be grown!
