Can you grow raspberries in winter? Usually planted in spring and summer every year

Raspberries can not be planted in winter. Raspberries are generally planted in spring and autumn, especially in spring. Raspberries are perennial shrubs with rich aroma, rich nutrition and good taste. Raspberry is also rich in amino acids, vitamin C, and zinc, iron, magnesium and other indispensable vitamins, is people's favorite fruit.

Raspberry is generally planted in spring and autumn every year, but it is mainly planted in spring. Spring planting is planted before seedling germination after soil thawing, but it should be noted that spring planting should not be too early. If the soil temperature is too early, it will have a certain impact on the growth of roots and affect the survival rate of raspberry planting. Generally, the temperature above 10 ℃ is the best time for spring planting of raspberry. The advantage of planting in autumn is that before the seedlings fully mature until the soil freezes, it is appropriate to plant early during this period, because at this time the seedlings lose less water, are easier to survive, sprout early and grow quickly in spring next year.

How to plant raspberry seedlings

1. Choose a flowerpot with a diameter of about 30 centimeters. It is recommended that the height be about 30 centimeters. Air holes should be left at the bottom of the pot, and the number of air holes should be as many as possible.

2. After preparing the flowerpot, you begin to prepare the nutrient substrate for planting raspberry. Add the peat containing fiber to the fermented cow dung and vermiculite, mix it evenly at 2:1:1, then put it in the flowerpot, and then plant the raspberry in the pot.

3. First take off the nutrition cup of the raspberry seedling, and then plant the raspberry seedling in the prepared flowerpot. The raspberry is buried about 2 centimeters deeper than the nutrition cup, and the extra leaves of the raspberry should be trimmed properly after planting.

4. Watering ensures the nutrient accumulation of raspberry branches and achieves the goal of blooming and fruiting earlier. Generally, after planting, raspberries will blossom around June, begin to mature in mid-July, and the fruit period of raspberries is long, which can last until mid-late September.

2. Planting techniques of raspberry

1. The choice of garden land.

Raspberries do not have high requirements for soil, general soil can grow, but grow better in fertile soil, raspberries should be cultivated in spring and autumn, the survival rate will increase.

2. Cultivation methods

After the land is determined, the line spacing is 2 meters and the plant spacing is 30 centimeters, and then the ditches and holes for planting raspberries are dug equidistant in a straight line of about 15 centimeters in length, width and depth. Raspberry seedlings will need to be soaked in water for about 4 hours before planting. Then start cultivation, about 1100 seedlings can be planted per mu.

Cultivation method: scatter the roots of raspberry seedlings into the pit, then trample the soil, deeply plant and bury it shallowly, planting standard: the root system and the surrounding soil cover no more than the original watermark of the seedlings in the garden, where there are conditions, there is no need to water or cover the film after planting, which can greatly ensure the survival rate.

3. Post-planting management

After the raspberry seedling is planted, it is mainly the underground rhizome, and the upper part of the ground is not as important as other fruits. Therefore, when the raspberry seedling is planted, the ground part only needs to be cut about 20 cm to improve the survival rate. After planting and before sprouting, land sealing drugs can be used to prevent the growth of large areas of grass. During the growth of raspberry, the soil is loosened after watering in particularly arid areas, and then paraquat is used to weed. It can save not only labor, but also energy.

4. Binding of branches

Set up stents for raspberries, which can be made of bamboo or cement. according to their own conditions, the stents can make the branches of raspberries distribute more evenly and improve the conditions of ventilation and light transmission. and the stent can also make the raspberry bear higher yield, fresh fruit can also be protected by ground pollution, but also convenient for the later stage of raspberry fertilization and harvest management.

5. Pruning and harvesting

The variety of Diguo red raspberry can bear fruit in the same year when it is planted in the same year, and the fruit can be harvested in the summer of July, and the mother branch after the fruit needs to be cut off from its base, keeping about 4 stout basal branches per clump that year, and then cut off the thin basal branches to facilitate fruit harvest in the later stage.

Diguo red raspberry can bear fruit alternately for several decades at a time, and the life cycle of a single plant can be up to about 20 years. The fruit ripening period of raspberry is inconsistent and can be harvested and processed in batches. The fruit can be harvested about 2 days after ripening. When there is no Rain Water or dew, the raspberries harvested in the morning will taste more fresh and delicious.

6. Overwintering against cold

If raspberries are planted in cold areas of the north, biennial varieties must bury the soil to resist the cold in winter to prevent buds and branches from freezing. When the soil is buried before freezing, the selected branches will be crushed and tied in one direction, sealing the soil, and when the soil is thawed next spring, the preservative soil will be removed and the branches will be placed on the shelf to allow the raspberries to grow normally.
