Bulbous begonia has fascinated many people, and many flower enthusiasts are not very clear about how to manage the bulbous begonia after potting. The author of this article summarizes the planting experience of many flower enthusiasts, and has specially consulted professional personnel of the flower farm many times, hoping to help flower enthusiasts in caring for bulbous begonias.
I. Daily management of bulbous begonia.
Bulbous begonia prefers cool, humid, semi-shaded environments, likes warm sunshine, and requires a long period of sunlight. The soil should be loose, fertile, well-drained, and slightly acidic. The overall growth temperature ranges from 5 to 26 degrees Celsius.
1. The best growth temperature is 15~23 degrees Celsius during the day and 10~15 degrees Celsius at night! This temperature is similar to our Guangdong's March and April. Every morning when I get up to look at the flowers, they are really different every day! It is particularly pleasing. Exceeding 32 degrees Celsius can cause dehydration, with soft and wilted leaves. Below 10 degrees Celsius is suitable for bulb formation.
2. Humidity: 70% to 80% during the growing period, and 60% during the blooming period.
3. Light: 10 to 12 hours, with strong light intensity of 8000 to 10000 lx.
4. Diseases and pests: powdery mildew, gray mold, red spider mites, mites, aphids, etc. Fertilize every 5 to 7 days and apply pesticides every 7 days. Remember not to use urea fertilizer.
5. Fertilization should follow the principle of "frequent application of thin fertilizer." During the growing period, apply a thin solution of decomposed cake fertilizer every 10 days or so. If you can apply 2 to 3 times of 0.5% calcium superphosphate solution during the formation of flower buds, it will be beneficial for the flowers to be large, colorful, and have a long blooming period.
6. Causes of flower drop: low temperature, insufficient light time, poor air quality, high humidity, and insufficient trace elements.
7. It's best not to move the pot: I once moved the pot in the heavy rain and the flowers died. This flower does not tolerate frequent moving, which is my past failure experience.
8. Plant the bulb with the concave side up, covering the bulb with soil by about 1 to 2 centimeters. Use small pots for seedlings, medium pots for planting, one bulb per pot. Prune branches and flowers in a timely manner.
9. Generally, one cycle every 3 months.
II. Beauty comes with suitability.
Any flower should follow its growth rules, beauty comes with suitability! Choose the right season to plant, and there will be no problem. I am in Guangdong, where the climate is difficult to handle, and I plant successfully every year. I believe everyone will do better than me! In Guangdong, it is suitable to plant from the end of October to April, and dormant in summer. Many flower enthusiasts from the north tell me that they are dormant in winter. Guangzhou's "Million Sunflower Garden" has held a bulbous begonia theme flower show for two consecutive years, and it's still ongoing this year.
Bulbous plants should be well managed: raise the bulbs, store the bulbs properly, and only then will you have good quality bulbs to plant next year. It is similar to Hippeastrum. By mid-April, my flowers have been raising bulbs for nearly a month, and the bulbs can be harvested at the end of the month.
Bulbous begonia is a very colorful family, with flower shapes including peony, rose, camellia, rose, azalea, etc. Similar colors are normal. For example, I have seen the above flower shapes with "Red and Pink Beauty." I wish everyone to have her beauty!
III. Dormancy issues.
Many flower enthusiasts often ask me: Can't bulbous begonia survive the summer? Can't bulbous begonia survive the winter?
Ha, little do they know, it's a bulbous plant! Generally, bulbous plants have a dormant period, and there's no need for summer and winter, she enters the dormant period.
I often tell flower enthusiasts: The flowers have bloomed several times, and they are not allowed to rest for a while. It's like people working during the day and sleeping at night to recover their energy. If you force them to work at night, can they really handle it?
Therefore, during the hot summer and the low winter temperatures (note: the climate varies from place to place, and the dormant period is also different. Pay attention to observations and summarize the rules. In Guangdong, we have summer dormancy but no winter dormancy), the plant enters a dormant period, retaining only the underground bulb. The bulb can remain in the original pot, stop watering, and place it in a cool place. If possible, keeping it at around 10 degrees Celsius (summer) or 2-3 degrees Celsius (winter) is better.
Dormancy period bulb management: Choose according to different conditions in each place. In Guangdong, I always harvest the bulbs in early May, dry them, wrap them in toilet paper, and place them in a refrigerator at about 4 degrees Celsius. Generally, after 2 months, the dormant period is broken, and red small buds appear. In Yunnan, the bulbs are left in the pot in a cool and well-ventilated place after November and planted again in the spring.
IV. Large and small bulb issues.
The larger the bulb, the more time it takes to grow: for example, extra-large bulbs take at least 5 years to form, and large bulbs take at least 3 years. The larger the bulb, the more germination points there are, thus more branches. Larger bulbs have more nutrients, and the resulting plants are relatively stronger.
Beautiful flowers require careful cultivation, and certainly more people will understand and like this flower, and more flower lovers will have her beauty!
