How to grow grapes in flowerpots? Mastering the key points of these planting methods is the key!

Potted grapes are glittering and translucent, exquisite and lovely, with green grape leaves and curved Saha branches. It is also interesting to expect the vine to sprout, blossom and bear fruit. Grapes are very popular in potted plants at home. How to grow grapes in flowerpots? Mastering the key points of these planting methods is the key!

I. planting method of flowerpot grape

1. Select the basin

Potted grape containers usually use earthen pots, which have good drainage and air permeability, and the price is cheaper. Pottery pots, porcelain pots, plastic pots (buckets), wooden cases, buckets, cement tanks and other containers can also be used. The shape of the container is round, polygonal, rectangular and so on. There are also differences in depth. Family potted plants generally use 25~30cm in diameter and 15~30cm in depth.

2. Prepare the basin soil.

It should have good air permeability and drainage performance, good physical and chemical properties, rich in organic matter and nutrients, suitable pH, no diseases and insect pests, and the matching ratio is 30% 50% for garden soil, 20% 30% for humus or organic fertilizer, and 20% 30% for river sand. The prepared culture soil should be loose, fertile and have excellent physical and chemical properties. The prepared basin soil can be disinfected with 0.1% formalin spray, 500ml for each cube basin soil, and high temperature steam disinfection if possible.

3. Planting time

One-or two-year-old grafted seedlings with roots or cuttings with roots can be selected and can be planted every year from February to March (nutrition bowl seedlings with roots can be planted from February to April to early May and June every year).

4. Seedlings and planting

The seedlings used in potted grapes can be cultivated by cutting, grafting, striping, etc., or grape plants of 1 ~ 3 years old can be transplanted with soil masses before sprouting. When planting, the hole in the center of the basin bottom is cushioned with tiles, put on a layer of pebbles, about 3cm thick, and then put into part of the basin soil to make a steamed bread, and the trimmed seedling roots are scattered on it in all directions, then fill the soil, and gently press it until the 3~5cm leaves the basin mouth, and then fill the soil and water until the bottom hole flows out. After planting, put it in a warm place and cover it with plastic film to preserve moisture.

5. Potted grapes must be placed on the sunny balcony

It can sprout and grow when the room temperature is above 10 ℃, the time temperature should not be less than 5 ℃, the flowering period should be 25 ℃, the berry expansion period should be 28 ℃, and the humidity of the basin soil should be kept at about 70%.

6. Water and fertilizer management

Sufficient water was irrigated once in 3-4 days in early spring, once every 2-3 days in June and July, and 1-2 times in dormant period in December. In the period of sprouting, flowering and fruit setting, sheep manure water was applied once with water and ammonia, phosphorus and potassium fertilizer was sprayed once on the leaf, especially zinc fertilizer was sprayed before and after flowering. The application of basic fertilizer is combined with soil exchange, and topdressing is applied in liquid during the growing period to prevent root burning caused by excessive concentration. The unfruited potted seedlings started from the seedling height 20cm (6-7 leaves), applied cake fertilizer and water once every 7-10 days, and applied to the end of September, the fruited seedlings had better be applied once every 5 days. Foliar fertilizer spraying is effective and economical by spraying 0.1%-0.3% urea for 3 times in the early growth stage, and spraying 0.3% potassium dihydrogen phosphate solution every 7-10 days for 3-4 times from the fruit expansion period. When watering, the water temperature should be close to the temperature of the basin soil, and it should be watered before 10: 00 in the morning and after 4: 00 in the afternoon. Generally, it should be watered every 2-3 days in early spring. With the increase of air temperature, the evaporation can be irrigated once every 2-2 days, and the watering times should be kept moist.

7. Leave the vine and set the branch

The grapes planted in that year can leave 1 or 2 elongated vines. The grape for many years can keep 3-4 extended vines, each vine has 1 fruiting branch every 3-4 years, those with ears have 3-4 leaves above the ear, and those without ears can grow to 3-4 leaves (reserved for next year's fruiting branches). Lengthening the vine length to about 1m, except for the extended vine, the auxiliary tip will grow 1-2 leaves to remove the heart. If the secondary results are promoted, no leaves can be left, forcing the winter buds to germinate ahead of time.

8. Getting on the shelves and binding

When the spring grape leaves extend the vine, insert three 1.3m long bamboo poles or sticks into the basin in a triangle, and the top is tied together and secured. With the growth of the main side vine of the grape, screw or tie up along the tripod (called Jinlong pan jade column type), pay attention to keep a certain distance between the vine and the vine, so that each ear is exposed outside. Can be dragged to the roof or outdoors with rope on the balcony.

9. Changing soil and pruning roots

The soil change period can be carried out at the end of autumn or before sprouting in spring, first pour through the water, then pour out the whole root system and basin soil, and then use bamboo pieces to loosen part of the soil mass covered with roots, and subtract part of the surrounding roots, the long roots can be reduced by about half of the length, and then re-planted in the new culture soil.

10. Adjust ear and yield

Adjust the ear in time before flowering, leaving one ear for each fruiting branch and removing the rest. 33~40cm diameter pot 2-3 years old can carry fruit 1.5~2kg, 4 years later 1 pot can carry fruit 5~10kg, larger pot will have higher yield.

11. Dormant overwintering

Winter pruning was carried out after harvest in autumn. 1 vine was cut at 70~80cm 1-2 years after planting, 1 fruiting branch was left at every 20cm, and 2-3 bud eyes were cut short. For more than 3 years, 4 extended vines were cut short at the 8th and 9th nodes (about 1m). From December of each year to January of the following year, potted grapes can be placed above 0 ℃, and the empty rooms or vegetable cellars below 10 ℃ can be dormant over the winter. generally, normal physiological dormancy can be completed within 30 to 45 days. Water should be watered once before or during dormancy to keep the basin soil moist. The dormancy of potted grapes can not be ignored, which is one of the important reasons for not blooming and fruiting.

12. Pest control

There are few pests in potted grapes, and the common diseases are downy mildew, white rot, anthrax, black pox and so on. The grape can be sprayed with stone sulfur mixture of 3-5 Baume degrees during the dormant period, and 1 ∶ 0.5 ∶ 200 Bordeaux solution or 500 times compound carbendazim solution is sprayed every 15 days after germination.

What is the size of the pot for potted grapes? When will the basin be changed?

Potted grapes should use larger flowerpots, and try to choose tile pots or purple sand pots and so on, such flowerpots are better breathable. In addition, flower friends should also choose fertile and loose soil as the matrix. Before potting, what florists have to do is to sterilize the soil at high temperature so that there are no eggs and bacteria in it, and the grapes can be planted without contamination.

When the grapes have been growing in flowerpots for about two years, the original soil fertility will be depleted. If the soil is not changed in time, it will be difficult for the grapes to bear fruit again. Therefore, Hua you should change the soil for the grapes, and if the container is relatively small, you should change it to a larger container. Flowerpots are usually carried out before the beginning of the growing period, so that the growth of the plant will not be affected.
