The cultivation method and precautions of potted grape
Compared with the introduction of the cultivation method of potted grapes and the maintenance precautions of potted grapes for most people, let's follow the editor to see the specific content!
Potted grapes are easy to grow, and you need to choose a suitable container to plant grapes. Terra cotta pots are more suitable. The depth of the pot should be at least 35~45 centimeters. The best time to plant is spring or early summer. Planting at this time can make the grapes grow stronger and better through the frost season.
Cultivation method of potted grapes
Potted grapes should be placed on the balcony or terrace, the most sunlit place outdoors, during the growing period to promote its strong growth. For potted grapes that have been cultivated for three years, it is necessary to change the potting soil once. The potting time can be chosen in early spring or autumn. Some cake fertilizer and bone meal should be added to the bottom of the pot. The watering of the potting soil must be controlled. If the environmental humidity is high and the potting soil is always waterlogged, it can easily lead to root rot and even fruit drop. Regular pruning is beneficial for its flowering and fruiting in the following year.
1. Growth habits
Grapes prefer a sunny and warm environment. Whether grapes can produce large and sweet fruits mainly depends on whether they have received sufficient sunlight during the growing period. Good photosynthesis can increase the quality of the fruit. Insufficient sunlight can lead to leafy growth without fruit, or even the leaves are in a state of徒长.
2. Soil
The root system of grapevines is relatively developed, so there are certain requirements for the size of the container. Depending on the variety of grapes planted by each gardening enthusiast, a pot mouth diameter of 25~35cm is suitable. The bottom of the pot must have a drainage hole to prevent waterlogging of the grapevine.
3. Fertilization
Grapes are rich in nutrients and have a high water content. Their growth is highly dependent on fertilizer. Do not fertilize at the initial germination stage. Wait until the germination is almost complete before gradually applying nitrogen fertilizer. In order to supply the increasing nutritional needs of the grapes, switch to phosphorus-potassium fertilizer or compound fertilizer before flowering. If you are not sure about the amount of fertilizer, you can dilute the fertilizer before applying it.
4. Watering
Grapevines are drought-resistant, and watering does not need to be too frequent. Also, if kept outdoors, it is necessary to check the potted grapes in time to prevent waterlogging. Severe waterlogging can lead to root rot. Grapes do not need too much water, and watering is not needed when the soil is not dry. It is most convenient and beneficial for grape growth to water thoroughly when the soil inside is completely dry.
5. Pruning
The shape of the potted grapevine is quite important. In order to achieve a good viewing effect, the shape of the plant can be pruned from time to time. Also, because grapes have a high demand for nutrients, in order to prevent unnecessary nutrient loss, timely pruning of poor-growing branches, leaves, or abnormally growing fruits should be done.
Precautions for maintaining potted grapes
When cultivating potted grapes, it is necessary to pay attention that they are prone to white rot disease, which can be controlled by spraying with Duomeiling solution every ten days for a month. Also, in spring, the period from the beginning of sap flow to the unfolding of leaves is called the bleeding period. If pruning occurs during this period, it can lead to excessive bleeding from the cut ends, and even kill the plant. Therefore, grape pruning should avoid the bleeding period.
