Generally, people who are more particular will put a few bottles of flowers at home. The life span of flowers is very short, mostly within a week, and it will be shorter in summer. Especially tulips, will wither in about two days. How can flowers last longer?
1) first, the roots of flowers should be cut obliquely, so that the water-absorbing part is large and more water can be absorbed;
2) Secondly, cut some off every day to ensure better absorption of water;
3) Also, don't soak the leaves of flowers in water, as they will rot. Be sure to remove the leaves soaked in water.
4) Change the water every day. If it is summer, in order to keep the water temperature from rising, you can also put a few pieces of ice in the vase; At the same time, it is best to fill the vase with water, which will not only keep the temperature of the water longer, but also increase the weight of the bottom of the vase and ensure the stability of the vase.
5) In order to make the flowers bloom longer, you can also put a little beer in the vase, or grind two aspirin into powder and put it in. Can prolong the life of flowers.
6) Among several kinds of flowers that ordinary families often buy, tulips have the shortest life and carnations have the longest life. If your host wants to be beautiful and economical, you should buy less tulips and more carnations. Especially in summer, tulips will soon wither.
7) Also note that chrysanthemums are generally not bought at home. Because chrysanthemums are generally used for worship.
8) Buy some silk flower flowers, mix them with flowers and put them in a vase, which will make them look rich and luxurious. Different silk flower can be reused with different flowers.
