How to grow blueberries

Blueberry is a kind of fruit that we are all familiar with, but in daily life, blueberry is a kind of fruit that we eat very little, and what we are more familiar with is blueberry jam. In fact, blueberries taste sour, sweet, delicious and nutritious, and they are a good kind of healthy fruit. So how are blueberries grown?

How to grow blueberries

1. To buy blueberry seedlings, it is best to choose the seedlings of 2-3 years. On the one hand, the seedlings are cheap, and on the other hand, they are adaptable and easy to grow.

2. If you plant blueberries in flowerpots, you'd better choose mud pots. The mud basin is breathable and cheap, but its disadvantage is that it is not very beautiful in black and gray. If you can't buy mud pots, you can choose pottery pots, followed by purple sand pots and plastic pots. Never use glazed porcelain pots. As for the size of the basin, 2-3 years of seedlings, choose a diameter of 25-30 cm basin on the line, avoid small seedlings and large pots. When you grow up, you will change the big basin. Of course, the bigger the mature plants of 4-5 years, the better.

3. Blueberry can grow healthily in acidic medium, and the PH value of cultivated soil is between 4 and 5, which is the most suitable for blueberry growth. This problem bothers many blueberry lovers, because the PH value of pastoral soil is generally between 6 and 7, and even the acidic soil sold in the flower and bird market has the lowest PH value between 5.5 and 6. After the blueberry seedlings are planted in the basin, they are kept indoors in the sun and ventilated for a week. This process is called slow seedling. After a week, you can move to the balcony for normal maintenance.

4. Blueberries like to get wet, especially in summer, they need enough water every day. But we should also be careful that there should be no stagnant water, otherwise the roots will rot. On a rainy day in Shanghai, blueberries don't have to go indoors, no matter how heavy the rain is, as long as the flowerpot is permeable. You can find that in the growing season, blueberry leaves are green and vibrant, and new leaves grow quickly when they are drenched in the rain for several days in a row.

5. Blueberries like the sun. They can't die in the sun at 40 degrees in summer. They can endure 40 ℃ ~ 50 ℃ temperatures in the surrounding environment during the growing season, as long as they are given enough water in the morning. Without enough sunlight, blueberries will stagnate and will not bear fruit even if they blossom.

6. Blueberries do not have a high demand for fertilizer, but fat will hurt it. There is a certain amount of rotten leaf soil in the medium, which can basically meet the growth needs of blueberries. Of course, if you want to eat your own blueberries, you still need the right amount of topdressing. It is recommended to use "Huaduoduo", 1 gram to 1000 grams of water, once every 7-10 days. This kind of fertilizer is so warm that it won't burn roots even if you use too much.

Plant blueberries in pots

1. Avoid the seedlings in a certain place and choose the varieties with good quality. We must distinguish between young seedlings. The key is to buy high-quality seedlings. I am afraid that they are fake seedlings, or those of poor quality that have been planted for a year but do not blossom or bear fruit, or inferior seedlings that bear only a few fruits.

2, but also to distinguish clearly, look at the picture of the seedling is not tall or three-year-old seedlings, but also to see whether the seedlings have been pruned, whether the growth of strong, you should also know a little bit of pruning techniques, ah, when pruning blueberry branches, pay attention to cut off the weak, sick and disabled branches, leaving long branches is better.

3. When growing blueberries, soil is the most important and crucial. Choose nutritious humus soil and soft and breathable organic soil. Don't choose soil that is too rigid. And usually when watering, do not water too often, the flowerpot should not be too humid.

4. The second is fertilization. It is recommended to use organic fertilizer when fertilizing, for example, chicken manure and rotten cake fertilizer. If it is compound fertilizer, use a few tablets at a time, not too close to the root, just put it on the edge of the flowerpot.

5. If it is a cold-resistant species, remember to spread something around the flowerpot or cover it with straw in winter. And can also be placed on the sunny balcony, Xiaobian where the central China region, directly on the open-air balcony, can also be smooth winter.

How to preserve blueberries

1. Water 3 to 5 cm a week. Be careful not to water too much.

2. Trim once every winter. In the first winter, cut off all the buds to make it more alive before it begins to bear fruit. It is also necessary to prune the branches that have stopped growing so that the fruiting part can grow better.

3. Every year after that, cut off the branches that grow too slowly and cut them from the sub-nodes. Also cut off all dead branches and twigs, as well as discolored and spotted parts.

4. For dwarf shrubs, prune all stems. The pruned plants will not bear fruit next season, so it is best to cut them in half at a time.

5. Pruning of branches can increase the growth rate from about 1 pound 3 to 1 pound 2. Try to cut off the collateral branches.

6. Fertilize blueberries. If your blueberry grows less than 30 centimeters a year (or, for dwarf shrubs, less than 10 centimeters), you can consider using natural fertilizer to speed up its growth. If possible, using organic fertilizer will not hurt the roots and provide the nitrogen needed for blueberries.

7. Harvest in late July or early August. For some species, including rabbit eyes, they mature later. The maturity time varies slightly with climate change each year.

The harvest of blueberries

The ripening period of blueberry fruits is different between Rabbit Eye and Nangao Cong. Generally, the harvest lasts for 20 to 30 days, usually once a week. The fruits should be picked manually when they are fresh, and can be harvested by machinery for processing. The diseases of blueberry are caused by fungal diseases, bacterial diseases and nematodes. China is a new introduction and cultivation area, and the occurrence of diseases and insect pests is less.

Blueberries taste unique, sweet taste with a hint of sour taste, especially delicious, is the favorite of many foodies. And blueberries can not only be eaten directly, but also can be made into a variety of delicious desserts and drinks. From this point of view, there are broad prospects for growing blueberries.
