What is the flower meaning of spider flower?
Flower meaning: The flower meaning and symbolic significance of spider flower: mystery.
The petals of the spider flower are light and graceful, and when in full bloom they look like butterflies dancing, which is quite interesting. It can be used in summer and autumn to arrange flower beds and flower borders, and can also be grown as a dwarfed plant for potted ornamental display. In garden applications, because it can tolerate partial shade, it can be planted under trees or on the shady side of buildings for viewing.
The spider flower opens in the evening and withers the next day during the daytime, so it is also called the flower of summer nights. Its brief life gives people a feeling of illusion and impermanence. This spider flower is native to the tropical regions of South America and is a very good pollution-resistant flower, with strong resistance to sulfur dioxide and chlorine gas; it can beautify the environment and is a very good pollution-resistant flower that can also grow well in heavily polluted factories and mines. It is also an excellent nectar source plant and can be used to extract high-quality essential oil.
When should spider flower be sown and when does it bloom?
Sowing: Sow in spring from March to April, by broadcasting. Because the seeds germinate uniformly, the sowing density should be small, and after sowing cover with 0.2 cm of soil. At 15°C, they germinate in 7-10 days. After emergence, thin the seedlings and fertilize. They can be transplanted at 2-3 true leaves. If sown in autumn in a greenhouse, they bloom in spring.
Flowering: The flowering period is from June to September (late summer and early autumn). Spider flower is an annual or biennial herbaceous plant, with a plant height of 40 cm-60 cm and flowers 3-6.5 cm wide. Some varieties can reach 1-1.5 m tall. Its flowering time is 75-110 days, with slight differences from place to place. When potted, attention should be paid to controlling the plant shape and preventing it from growing too tall, so as not to affect flowering.
What are the planting methods for spider flower?
1. What kind of environment is suitable for spider flower?
The quality of the soil directly affects the quality of spider flower seedling development. If the soil is very good and the growing environment is very good, then the workers will have much less trouble caring for it. Spider flower is not strict about soil restrictions, and sandy gravel soil, yellow mud, and clay are all acceptable, but soil with a high sand content generally has average germination. Spider flower is afraid of waterlogging and requires flat terrain that drains easily. When the dog days arrive, rainfall increases, and water must be able to drain away immediately, otherwise large-scale seedling death may occur. The nursery must above all be good for drainage, and the soil only needs to be about average, with sufficient sunlight.
2. Land preparation
1. Plowing: Spider flower is very sensitive to fertilizer. If the soil has sufficient fertilizer, the flowers will be larger and more colorful, and the plants will be healthy. However, the soil at most construction sites is nursery land with only average fertilizer, so if you want colorful flowers, you need to apply enough farmyard manure before sowing, broadcasting 3-6.5 t of cow dung and pig manure per mu. After applying the fertilizer, plow once deeply and harrow once finely, so that the soil and nutrients are mixed evenly together, with no large clods of soil, which is convenient for sowing and improves the germination rate.
2. Making beds: In order to facilitate the necessary management work during the first-year growth period of spider flower seedlings, such as irrigation, weed clearing, and fertilization, Changjing Landscape suggests making the land into standard beds 1.4 m wide and 12-20 m long, with the specific size determined by the topography.
3. How to plant spider flower
The seeds of spider flower are medium in size and have fairly good germination ability, so shallow sowing is recommended, with soil cover no more than 5 cm. Mostly broadcasting is used for planting. Choose a windy day, mix the spider flower seeds into moist sand, and then broadcast them on the ground. After sowing, cover the soil by hand or by mechanical raking, then irrigate once after covering. In about 6-12 days, the germination rate can be improved.
4. How to care for spider flower
There is very little maintenance and management work during the growing period of spider flower. It basically has no diseases and pests, and its growth is vigorous. The main tasks are all concentrated around the flowering time. Before flowering, apply 30 kg of compound fertilizer per mu. Fertilizing before flowering is to lengthen the flowering period, and the flowers produced are more beautiful in color. Do not fertilize during the full flowering period. During the blooming time of spider flower, more water is required, and during this period, watering should be done at the right time according to the weather conditions.
