What is the flower language of blue thistle?
In the 13th century AD, a Scottish castle was raided and surrounded by a Danish army. On the way, this Danish army accidentally blundered into thistle flowers, and because they were
pricked by the thorns of the thistle flowers, they cried out in pain. As a result, they were spotted by the Scottish army, which immediately rose up to attack, and in the end won a great victory. To commemorate the victory of this war, the Scots regarded the blue thistle flower as the national flower. The flower language of this flower is “blessed by heaven”. People born on this day are favored children of heaven specially cared for by heaven, and everything goes smoothly whether in studies, career, or love.
When should blue thistle be sown to bloom?
Sowing:
Blue thistle is produced in northern Xinjiang and is widely distributed in Europe and western Asia. It is cultivated in cities such as Beijing and Nanjing in China. Because the suitable germination temperature for blue thistle seeds is 18-22°C, both spring sowing and autumn sowing are possible. Spring sowing is generally carried out around early April, while autumn sowing can be carried out in early September when the temperature is suitable. Of course, planting must be done according to local conditions. For example, autumn temperatures in the north and south differ greatly, so local temperatures must be paid close attention to.
Blooming:
Blue thistle belongs to biennial herbaceous plants. The flowers are 2.5~6 cm wide, the plant height is 42~75 cm, and the flowering time is 70~115 days, with slight differences from place to place.
What are the planting methods for blue thistle?
1. What kind of environment is blue thistle suitable for
The quality of the soil determines the quality of blue thistle seedling growth. If the soil quality is very good and the growing environment is very good, then employee maintenance will be much more convenient. Blue thistle is not strict about soil; it can be sandy soil, yellow mud, or residue soil, but sandy soil with a lot of sand generally has average germination. Blue thistle is afraid of flooding, so it needs higher terrain that drains easily. As rain gradually increases when the dog days arrive, accumulated water must be drained immediately, otherwise some seedlings will die. The key for a nursery is to be conducive to drainage; the soil quality just needs to be about right, and sunlight should be sufficient.
2. Land preparation
1. Plowing: Blue thistle responds very quickly to fertility. When the soil is fertile enough, the flowers it opens are large and gorgeous, and the plant is healthy. However, some soil at landscaping sites is from nurseries with only average fertility. Precisely because of this, if you want gorgeous flowers, you must apply sufficient fertilizer before sowing, spreading 5~6 tons of cattle and chicken manure per mu, then plowing once and harrowing once after topdressing, so that the soil and fertilizer are evenly mixed with moisture, with no large clods, which is good for sowing and increases emergence.
2. Making beds: In order to facilitate necessary maintenance management such as watering, weeding, and fertilizing during the annual growth period of blue thistle seedlings, Changjing Landscape recommends making the land into beds with a fixed width of 1.6 m and a length of 15~20 m, with the actual situation depending on the plot.
3. How to plant blue thistle
Blue thistle seeds are medium in size and have good soil-piercing ability, so relatively shallow sowing is recommended, with a covering soil thickness of no more than 4 cm. Most use broadcast sowing. Choose weather with little wind, mix blue thistle seeds into wet sand, and evenly scatter them on the ground. After planting, manual soil covering or mechanical raking can be used to cover the soil. After covering with soil, irrigate once, and emergence can generally be increased in about 7~10 days.
4. How to care for blue thistle
The management workload during the growth period of blue thistle is relatively small. It has no diseases, and its growth condition is good. The main matters are concentrated during the flowering period. Before flowering, apply 30 kg of chemical fertilizer per mu. Fertilizing before flowering is to make the flowering period longer, the flower quantity greater, and the color more vivid. No fertilization is needed when it is in full bloom. Blue thistle needs more water when it is flowering, and during this period the rainfall situation should be referenced to decide whether watering is needed.
