Safflower sorrel is a perennial erect herb of the family Sorrelidae. Planting often planted in large areas, small flowers are numerous, splendid and lovely, can be used to arrange into flower beds, flower landscapes, flower bushes, flower groups and flower stands.
The weather is dry and muggy in summer, especially in the high temperature stage of midsummer in July and August, Safflower sorrel sometimes appears forced to dormant, yellowing of flowers and leaves, and reduced flowering.
What if in the summer safflower sorrel appears leaves dry up? Don't take it lightly, and observe whether it is caused by the damage of spider mites. When Safflower sorrel is attacked by Spider mite, white spots first appear on its leaves, and then scorch and fall off, which will seriously affect the appearance.
Once the area of harm is large, drug prevention and treatment will not work. So what can be done to keep safflower sorrel safe from red spiders?
1.Prevent it in advance.
Carefully carry out regular insect observation. Because the red spider that harms the safflower drunken berry does not have the ability to fly, and can only spread by crawling and with the help of wind, its spread is gradually expanded from point to surface, and the initial damage speed is limited, and it takes a certain period of time to spread and reproduce to cause large-scale damage. Once the punctate damage plant is found, immediately pull out all the leaves and all the leaves of the adjacent plants, and take it to a place away from the safflower drunken berry to burn, so as to effectively curb the breeding of the red spider.
Keeping the floor moist and well ventilated is the key to prevention.
2.Medication cleanup.
The stems and leaves of the plants infested by red spiders are yellow, the leaves fall off, and the growth is poor, which is not easy to detect in the early stage of occurrence, and it is more serious when it is found, so it is necessary to focus on prevention.
If it is not observed at the beginning of the occurrence, it is more serious by the time it is discovered. Then you can use 5% avermectin 3000 times liquid spray to control its harm; It can also be sprayed in the afternoon on a sunny day, sprayed once every 3 days, and sprayed 3 5 times in a row.
Try not to use drugs in the early stage of red spider damage, so that in addition to killing its main natural enemy, the carnivorous red spider, it will also make the red spider become drug resistant.
Here are some breeding and management tips for growing safflower sorrel:
1) Choose a well-drained, sandy loam with a lot of humus. In colder regions, it can only be cultivated in greenhouses.
2) Heavy stubble should be avoided as much as possible when transplanting the ground planted sorrel branches, and soil change and disinfection should be paid attention to when potting sorrel plants are turned over and divided.
3) Strengthen fertilizer and water management during the vigorous growth period, and turn the pot frequently for potted sorrel.
4) Strengthen pest control, take measures such as overwintering and cold protection.

Watering and topdressing, because of the summer weather, may make the nutrients of the leaves and safflower unable to keep up, so it will lead to the phenomenon of dryness.

<> supplemental light, the summer wilting of sorrel may be caused by lack of light, and it needs to be transferred to a ventilated and cool astigmatism place for maintenance; Timely replenishment of water, long-term growth in the lack of water environment sorrel leaves will also wilt, coarse macro needs to take the method of soaking pots to replenish water for sorrel; Leaf spot will also cause yellowing of the leaves of the sorrel, which needs to be sprayed with benzene lutten solution**.
If the sorrel is placed in a shady environment for a long time in summer, resulting in the inability of the leaves to photosynthesize, the sorrel is prone to wilting and yellowing. At this time, the sorrel should be transferred to a well-ventilated, well-lit balcony for maintenance.
The sorrel needs more water during the growth period, and it needs to be watered once a week when maintaining the sorrel in the summer, and if it grows in a water-scarce environment for a long time, it will make the sorrel wilt. At this time, you can take the method of soaking the pot to replenish water, you can fill the small pot with an appropriate amount of water, put the pot into the pot, and seep water into the pot through the hole at the bottom.
After the sorrel is attacked by leaf spot disease in summer, brown lesions will appear on the leaves, which will affect the normal growth of the sorrel and cause the whole leaf to wilt. It is necessary to spray diphoxyl solution every 2 3 days**, and the condition of yellow leaves can be improved after a period of time.
In the summer heat, the sorrel will enter a short dormant period, during which the nutrient demand is low, and if too much fertilizer is applied, the sorrel leaves will wilt. At this time, it is necessary to pour a large amount of water into the pot to dilute the fertilizer in the soil.

Safflower sorrel is a perennial herbaceous plant, the plant is relatively short, the leaves are very dense, and the flowers are colorful and bright, and the flowering period is long, which has become a must-plant "hard vegetable" in the courtyard terrace garden of many flower lovers. Safflower sorrel grows in the open field in full sunlight and in the shade of trees, and it should be said that safflower sorrel is a very good plant to raise. But why do the leaves dry up when they still roll in the summer?
I think there may be several reasons:
1. High temperature and lack of water lead to dry leaves.
We know that safflower sorrel is a light-loving plant that grows vigorously in sunlight. However, when encountering a high temperature of more than 35 in summer, such as picking up the fruit in the environment of continuous exposure to the sun, the lack of timely watering may cause drought and water shortage of safflower sorrel, resulting in poor plant growth, and the phenomenon of wilting and drying of leaves in the later stage.
2. Pests and diseases cause leaves to dry up.
Affected by the high temperature and dry climate in summer, safflower sorrel is susceptible to the damage of spider mites and leaf spot. If the prevention and control is not timely, it often causes yellowing and dryness of leaves.
3. Dormancy in summer leads to dry leaves.
Due to the high temperature in summer, especially in the month, under the condition of full sun exposure, the safflower sorrel plants are forced to enter a dormant state, basically stop growing, and some leaves begin to wither. The bulbs continue to multiply in the ground and germinate again in the fall.
So how to maintain the leaves to achieve lush leaves?
1. Avoid sun exposure in midsummer.
Although safflower sorrel loves light, the temperature is too high in midsummer, so if you want to avoid the plant going dormant or prevent the leaf wilting due to poor watering. In hot weather, it should be placed in a semi-shaded place or an indoor astigmatism place for maintenance. In other seasons, plenty of light can be enjoyed.
However, it is also important to note that it should not be placed in a shady place, as this will cause it to grow and be prone to lodging and difficult to flower.
Through our introduction, I believe that you have a deeper understanding of how to maintain the cultivation methods and precautions of safflower sorrel in order to have lush leaves.
Soup, all have a good brain tonic effect. But it belongs to the category of wild vegetables, don't eat more, it contains a lot of sorrelic acid. >>>More
