The florescence of a string of red flowers and its regulation and control methods if the management of florescence is done well

A string of red flowers bloom for a long time, from July to November every year. It is the most common flower to decorate the National Day, bright and uniform flowers, long tube-shaped, blossoming connected into a string, like a string of red firecrackers, set off a festive and peaceful atmosphere. A string of red in autumn stands tall in the green leaves, full of vitality, as if the heart immersed in love is burning.

In addition to having a bright red appearance, a string of red also has sweet nectar. There are probably not a few children who have tasted a string of red. I remember when I was a child, whenever there was a string of red blossoms in school, the children would huddle into the flowers, pull out the flowers at the top and suck the sweet nectar from the roots. Of course, most of the red flowers are planted on the side of the road, and there are a lot of dust and bacteria in the flowers, which can easily lead to gastrointestinal diseases if eaten. Therefore, let a string of red sweet honey stay in the memory of childhood.

The main methods of controlling the florescence of safflower include sowing by stages, cutting by stages, picking buds and controlling flowers and so on.

2. Cutting by stages

Cutting can shorten the seedling stage and promote early flowering. If the cuttings are cut at the right time according to the need for flowering, they can bloom as scheduled. Under suitable environmental conditions, the cuttings can take root in about 3 weeks, put on the pot after 1 month, and blossom after about 2 months of culture. Such as autumn cuttings, indoor maintenance in winter, can blossom in the early spring of the following year; cuttings from June to July in summer, strengthen water and fertilizer management, can bloom in the same year.
