How to Care for Grapes in June
For many girls, the knowledge of how to care for grapes in June and the detailed management methods of grapevines in June is quite intriguing. Let's take a look together.
"Violet breasts and green vines climb high, starry clusters gather, transparent and crystalline. The branches are as beautiful as brocade curtains, and the taste is comparable to that of醍醐 or jade broth." The history of grapes is long and enduring. They are sweet and sour, crystal-clear, and have always been praised by many literati. Grapes are not only delicious but also contain many beneficial elements for the human body, holding an unshakable position in people's lives. Growing grapes is undoubtedly profitable, so how should we manage grapes in June? Let's find out together.
1. Secondary shoot management
Usually, it is necessary to remove the top of the branches where there are 5 to 8 leaves above the flower clusters, leaving three leaves at the top for future secondary topping. For the secondary shoots in the middle and lower parts, they should be treated differently depending on the grape variety. For example, for varieties like Hongdiyu and Hongmeiren, three leaves should be left before the final topping.
2. Fruit thinning management
Fruit thinning has a significant impact on the growth of grapes, so it must be taken seriously. Moderate fruit thinning can make the fruits evenly distributed, improve coloration, and make the clusters more beautiful, effectively enhancing the quality of grapes and bringing more profits to growers. When thinning fruits, one must be decisive and not hesitate to remove them, as incomplete operations can have adverse effects on the plants. The number of fruit berries left during thinning varies by variety, and if an expansion agent is to be used on the clusters, it should be applied before thinning.
3. Bagging management
The bagging work in June must be done well, as it has a significant impact on grapes, even affecting the prevention and control of diseases and pests. Before bagging, a fungicide and insecticide should be applied to the plants, usually in the morning or evening on sunny days, and not during the high temperatures of noon or after heavy rain. After the weather is suitable and the applied pesticides have dried, bagging can proceed. The specific operation involves opening the paper bag and then putting the fruit cluster inside from top to bottom, securing the bag opening at the peduncle.
4. Water and fertilizer management
In the late June, grapes are in the fruit expansion stage and require a lot of water. Grapes should be watered every 3 to 4 days until the fruits become soft and start to enter the coloring stage, at which point watering can be stopped. During the coloring stage, it is important to drain excess water from the grapevines. At this time, scientific fertilization should also be carried out without overdoing it, mainly using organic fertilizers, and also applying phosphorus, potassium, and calcium fertilizers appropriately. After 5 days of fertilization, another watering should be done to ensure thorough irrigation.
5. Disease and pest management
In June, high temperatures and frequent rain make grapes prone to diseases and pests, which should be prevented and controlled in a timely manner. Bordeaux mixture or carbendazim can be applied to grapes every 10 to 15 days. Special attention should be paid to the prevention and control of anthracnose and white rot. Medication should be applied immediately after heavy rain and when the leaves are dry. If rain occurs after application, a supplement spray should be performed. For grapes grown in the open field, downy mildew should also be guarded against, using necessary preventatives and treating with anke after the disease occurs.
6. Weeding
In June, weeds grow quite vigorously. If they are not removed in time, they will compete with the plants for nutrients and may cause diseases and pests, affecting the growth and development of grapes, so they should be removed promptly.
