Marguerite daisies wither quickly in summer; do these few steps and add 1 ingredient, and they will bloom in a bursting pot all summer long

Marguerite daisies are very beautiful flowers. Everyone says marguerite daisies are difficult to get through summer, while in other seasons they can easily burst into a full pot with rough management. The picture below is a friend's marguerite daisy. Just 2 days ago it was still lush and green, but these 2 days it has begun to wither extremely fast, which is really worrying. So in summer, how should marguerite daisies be cared for?
This picture is from another flower-growing friend. He has his own special method for growing marguerite daisies, keeps dozens of pots at home, and now the flowers are all blooming especially beautifully. Taking advantage of the weekend, the editor specially went to ask him about care methods. Let's see what secrets this expert's little marguerite daisies have for getting through summer.
Secret 1 for getting through summer: choosing the soil. If you want them to get through summer safely, you need to start preparing in early spring, and that means changing the soil for the little marguerite daisies. For choosing this soil, you only need to make sure it is fertile and airy, then add some homemade humus soil to the soil. This can promote root growth, strengthen the plant's resistance, and prepare it for getting through summer.
Secret 2 for getting through summer: reasonable fertilizing. With high summer temperatures, little marguerite daisies also grow relatively slowly, but if they are going to bloom they will still consume a lot of nutrients. If nutrients cannot keep up, they will also easily wither. Fertilizing in summer requires special care, because if you are not careful you will burn the seedlings. So it is best to choose organic liquid fertilizer, and you can spray foliar fertilizer once a month. But the more diluted the liquid fertilizer, the better, so that the normal growth of the little marguerite daisies can be ensured.
Secret 3 for getting through summer: scientific watering. Summer weather is really too hot, and water evaporates quickly. Many flower-growing friends often cannot control their hands and water too much, causing the flowers to be watered to death. Marguerite daisies in summer generally only need watering once every 2-3 days, and you should adapt to local conditions according to different environments. Most importantly, decide based on whether the potting soil is dry or wet, and water again only when it is dry. You can also use a flower and plant detector to help. Just insert it into the soil, and water according to the data changes. It is very simple and convenient.
Secret 4 for getting through summer: controlling light. Little marguerite daisies love light. At other times, full-sun care is most suitable. But in summer, if they are directly exposed to the sun for 1-2 hours, the leaves will quickly wither. Especially after rain and then blazing sun, when the potting soil temperature is high and humidity is high, it will directly make the little marguerite daisies over. So in summer, you should properly shade the little marguerite daisies, and you can put up a shade net.
After doing the above four points well, the most important thing is still ventilation. If it is stuffy for a day, it will quickly be over too. This applies to all flowers. No matter what flower it is, once it gets stuffy, it is basically finished.
