Sunflowers certainly don’t sleep at night. If it were, they could not have tilted so that the flowers were facing east at sunset but still facing west at dawn. Plant cells, including roots, multiply and some cells become larger.
At night, in their absence, the sunflowers look east again and await the return of the sun. They do this until old age when they stop moving. So the old flowers are still waiting in the east for the visit of insects, which spread pollen and form new sunflowers. These flowers will also follow the sun.
But flowers that close at night, such as tulips, hibiscus, poppies, and crocuses, aren’t sleepy. They are just very developed.
Why do sunflower heads fall off There have been days when I had to water my sunflowers morning and evening to prevent them from blooming. When a sunflower head has finished blooming, when it has been pollinated and is getting heavy with seeds, it is quite normal for the head to bend and fall.
They don’t look at each other. When the sunflower is ripe, it stops following the sun and settles to absorb the falling rays. Fully developed flowers usually stop and stay in an easterly direction, but there is always a rebel in the bed who chooses a different view.
In fact, they don’t, Harmer said. The older sunflowers still face east. A young sunflower plant not only follows the sun during the day, but also rearranges itself at night in anticipation of sunrise.
While they are beautifully beautiful, they are also steeped in history and meaning. Sunflowers symbolize worship, loyalty and longevity. Much of the meaning of sunflowers comes from their namesake, the sun itself.
The flower of a typical sunflower is called a head. In common sunflowers, the outer yellow petals are called ligula flowers, and the center is made up of numerous disc-shaped flowers that are crowded. The entire head is surrounded by numerous green leaves called phyllars.
Sunflowers need full sun, which means at least six hours of unfiltered sun every day. Sunflowers that get enough light will produce many blooms that will last all day, so they are always exposed to the sun. Because they are so sun worshipers, it is difficult to grow healthy sunflowers in a bright garden.
No, they just hang around until the sun comes up again. If so, we’ll call them sunflower blossoms. Or the flowers of the heavenly body.
While miniature sunflower varieties are about 2 feet tall and giant varieties can grow over 3 feet tall, standard sunflowers are generally between 6 and 10 feet tall. Depending on the variety, sunflower plants can mature from seed in 70-100 days.
Water the sunflower several times a week.
Take the wilted flower and cut the stem at an angle of about 1 inch from the end of the flower that had already been cut off. 2. Put three teaspoons of sugar in the warm water of the vase, add the withered flower and let it sit for a while. Sugar makes a good impression on you!
The true flower of the plant may still be in good condition, but the withered stem will cause the flower to die. To avoid this, place the sunflowers in a tall vase with plenty of water. The extra support at the bottom of the shaft can help keep the top of the shaft in its rigid form.
about 7-15 days
Although sunflowers need a lot of water to germinate, they only need one inch of water per week during the growing season. Use a water sprayer to lightly water once a week until every 6 inches of soil is wet.
Plants that open and close their leaves in response to day and night cycles are known as nictynastic.
