Life knowledge series: An introduction to the characteristics of sunflowers blooming at what time and a description of the flowering season of green plants and flowers, let's learn about it together.
When do sunflowers bloom (how to plant sunflowers yourself) what should be paid attention to when planting sunflowers, and how to plant sunflowers yourself. Sunflowers usually bloom in all seasons, mainly in summer and winter. Their flowering period is from mid-July to late August, which can last for about two weeks and can be seen for a long time. If the plants are put in water, they can only maintain for 3-4 days. If preserved with strong tea water, the time can be extended.
How long can sunflowers be kept in water during the flowering period: The flowering period can bloom in all seasons, mainly in summer and winter, from mid-July to late August, which may vary slightly by region. The flowering period usually lasts two weeks, with a long viewing time. The blooming flowers look bright, like the sun, and they rotate with the sun. In addition to being suitable for display and having ornamental value, the seeds also have economic value and oil extraction functions, making it a versatile plant.
Second, the flowering habits of sunflowers: When sunflowers bloom, it usually takes 6-9 days for the flower disk to bloom from the ligulate flower to full bloom. Sunflowers bloom from the second to the fifth day, with a lot of conversation during these days. Sunflowers bloom at 4-6 am and can be pollinated the next morning. If not pollinated, these flowers can survive for 7-10 days. Sunflower flowers are still very striking, with single or double petals. At first glance, it looks like a large disk. There are two types of flowers on the sunflower disk, ligulate flowers, and tubular flowers.
3. How long can sunflowers live in a vase: Insert the plant into water, cut the base at a 45-degree angle to increase the water absorption area, and make it easier to survive. If treated with clean water, it can only be treated for 3-4 days. If pickled with strong tea water, the time can be extended. Also, note that it cannot be treated in strong sunlight and may be exposed to diffused light, which is beneficial for survival. In addition, preservatives can be added to keep the flowers fresh.
Fourth, what should be paid attention to when raising sunflowers? Sunflowers are usually maintained by annual flowering plants. They can be seen in summer and autumn. They are very popular ornamental flowers, easy to grow, and suitable for driving and training after warm spring. They can be directly sown and propagated, and children can raise them well.
Before sowing, observe the average outdoor temperature. If the minimum temperature is above 18 degrees, sunflowers can continue to grow. Sunflowers should be fixed in one place to avoid transplanting. Once transplanted, it is easy to fall off. Sunflowers can be planted until frost arrives, with temperatures maintained between 18-33 degrees.
Sunflowers can bloom about 80-120 days after planting and begin to produce seeds. Sunflowers can be planted indoors in winter, in frost-free areas all year round, but it is best to plant after warm spring. Nowadays, many of the sunflower varieties we buy are hybrid varieties. If you choose potted sunflowers, you must choose some dwarf varieties, including those with a height of about 30 centimeters, and of course, there are also giant sunflowers that can grow to 3-4 meters tall.
Sunflower seeds can be wrapped in a wet paper towel before sowing. The seed packet is inside. Fold the paper towel slightly, then keep the paper towel moist and place it in a warm place. After 2-3 days, the sunflower seeds can be taken out and planted in the soil. If the seeds are planted directly in the soil, it may take two to three weeks to germinate, but if wrapped in a wet paper towel, the seeds will germinate in about three days, so be careful not to damage the roots after germination.
After sowing sunflowers, they should be placed in a position with plenty of light, with more than 6-8 hours of sunlight every day. Avoid placing them in shady areas and give them as much light as possible every day. Of course, avoid strong wind erosion, or the branches can easily be blown over.
When planting sunflowers, choose deep, loose, breathable, and well-drained sandy soil. The soil should not accumulate water or remain moist for a long time to avoid root rot. If necessary, dig a hole 60 centimeters deep and completely loosen the soil. Sunflowers are not very picky about soil, but the most important thing is to maintain soil drainage and avoid waterlogging. If the soil is very poor, it is necessary to add appropriately matured fertilizer or organic compost.
Only one sunflower needs to be planted in each pot. When sowing, press the seeds into the soil by about 2-3 centimeters. During the seedling care period, the soil should be slightly moist, and there will be no problem as long as there is no waterlogging. After the seedlings grow strong, try to provide sunlight, control watering, and the soil should not be moist for a long time, watering once a week with seepage, and slightly increasing the watering frequency during dry and hot weather.
Sunflowers do not need to be fertilized frequently. Every three to four weeks in spring and summer, a slow-release fertilizer can be supplemented. It is not recommended to use concentrated fertilizers but can be applied directly with some long-acting organic granular fertilizers.
The above sharing on the characteristics of sunflowers blooming at what time and the description of the flowering season of sunflowers, hoping to be helpful to you!
