How to raise blueberries more vigorously, planting management methods and matters needing attention of blueberries (Figure)

For the public, blueberry is a very expensive fruit. Generally, the blueberries we buy from fruit shops are grown on a large scale. In fact, as long as the conditions are right, we can also plant plants at home. So, how to raise blueberries to be more energetic? Today, Uncle Gardener will tell you about the planting management methods and precautions of potted blueberries!

Blueberry fruit

1, variety selection

Some blueberries can pollinate themselves, while others need pollination trees to bear fruit. For example, rabbit-eyed blueberries need pollination trees. Family potted blueberries must pay attention to the choice of varieties. For example, in South China, it is best to choose varieties such as Sharpay and Aiwenlan. These varieties can pollinate themselves, and there are many home potted blueberries.

2. Pot soil preparation

Blueberries like acidic soil, and the optimum pH value is 4.5-5.5. Potted soil should be loose, breathable and rich in organic matter, and can be mixed with aged bark, sawdust, straw and humus to make potted soil. At the same time, it is recommended to use flowerpots with good air permeability. Never use pottery pots or porcelain pots. You can use pottery pots or sand pots, and then you can use plastic pots.

3, watering problems and climate

A very important factor to ensure the fruiting of potted blueberries is to ensure that blueberries can withstand low temperature dormancy below 7.2℃ in winter, and the lowest temperature they can tolerate varies with different varieties. For example, as a flower viewing, there is no need for low temperature restrictions. Blueberries have shallow roots and are sensitive to water shortage, so the basin soil should always be kept moist and free of water, which is different in different growing seasons of blueberries. In the vegetative growth stage, the most suitable water condition can always be maintained, which can promote the plants to be strong. However, in the fruit development stage and before the fruit matures, the water supply must be reduced appropriately to prevent the rapid growth of nutrition from competing with the fruit for nutrients. After the fruit is harvested, the most suitable water supply can be restored to promote the vegetative growth. Reduce the water supply from Mid-Autumn Festival to late autumn, so as to enter the dormant period in time. In order to keep the acidity of the soil, it is suggested that the dosage is 3-5 degrees vinegar, and 500 ml is applied every month, including half a tablespoon of vinegar.

4. Fertilization management

Blueberries have low requirements for fertilizers, and the contents of nitrogen, phosphorus, potassium, calcium, magnesium and other elements in their plants are very low. Compared with other fruit trees, blueberry is an oligotrophic plant, so it can't be fertilized frequently. Organic matter can be added to the soil when planting, and attention should be paid to the thin application of chemical fertilizer in the later stage. It is best to use acidic fertilizers, such as pollution-free cationic activator Wang Kehua No.2, which can promote the flowering and fruiting of blueberries.

5. Overwintering protection

Although dwarf blueberries and semi-tall blueberries have strong cold resistance, freezing injury still occurs from time to time. The main manifestations are bolting and flower bud freezing injury in winter, and all the aboveground parts can be frozen to death in special years. Therefore, wintering protection is also an important measure to ensure the yield in blueberry cultivation in cold regions. For example, piling snow to prevent cold, coloring trees to protect them and so on.

When blueberries bloom,

Tip: It is best to plant blueberries in flowerpots between autumn and the following spring. After blueberry is planted in autumn, it blooms a little in the second year and blooms and bears fruit normally in the third year. The fifth year is full of fruit. Family potted blueberries can bear fruit for 35 years as long as they are cultivated properly. Oh, the fruiting period is very long.
