Blueberry Tree Care & Propagation Guide
We need deep and fertile soil to raise blueberry trees. We usually need to provide sufficient light, but we need appropriate shade in late summer and early autumn to avoid sunburn. Water properly at ordinary times, keep the basin soil moist during the growth period, and water it once a week in winter. In addition, compound fertilizer should be supplemented every half a month, and leaf fertilizer should be applied appropriately to promote the growth of blueberry trees.

Blueberry Tree Care in Detail

Blueberry Tree Care & Propagation Guide

Blueberry Tree Watering

The growth of blueberry tree requires sufficient water, and a humid environment is more favorable for plant development. During its growth period, it is necessary to water frequently to keep the soil moist. At the same time, it is also necessary to spray water appropriately to improve the humidity of the air. In winter, the climate is cold, and watering should be reduced. Usually watering once a week is enough, and there should be no ponding.

Blueberry Tree Soil

Planting blueberry trees must be carried out in the place with deep soil layer and loose texture, and the pH of the soil should be between 4.1-5.6, so that the plants can grow healthily. At the same time, rich organic matter is very helpful for its development. Before planting, the soil should also be applied with sufficient base fertilizer. It should be cultivated regularly. It can also be covered with pine needles or sawdust.
In order to ensure that the growth and development of blueberries can be completed on schedule, appropriate growth matrix is essential. It is best to let blueberries grow in relatively loose and porous places, with good drainage and air permeability of acidic soil. The soil itself has certain basic fertility and can provide nutrients.

Blueberry Tree Light

Blueberry is suitable for growing in an environment with sufficient light, so it must be planted in the sunny place to make it fully exposed to light, which can not only make its leaves green, but also promote flower bud differentiation, which is very helpful for plants to blossom and bear fruit. Proper shade is needed in late summer and early autumn to avoid withering of branches and leaves due to exposure.
Blueberry is a kind of berry, so its fruit contains a large number of nutrients, which need more light to synthesize and store photosynthesis. If blueberries are not exposed to light for a long time in a humid and dark environment, blueberries may not grow in vain.

Blueberry Tree Temperature

When Propagating blueberry trees, we should pay attention to sufficient light, grow in the sun and fully absorb sunlight; However, when it is strong in summer, we need appropriate shading. We also need to control the temperature at 10-25 ℃, and the temperature in winter should not be lower than 0 ℃; In Propagation, we need to keep the soil moist without ponding. We also need to apply nitrogen, phosphorus and potassium compound fertilizer every half a month during the growth period of blueberry trees and spray potassium dihydrogen phosphate leaf fertilizer.

Blueberry Tree Humidity

The growth of blueberry tree requires sufficient water, and a humid environment is more favorable for plant development. During the growth period of blueberry tree, we must water frequently to keep the soil moist, and spray water appropriately to improve the humidity of the air. In winter, when the weather is cold, we should reduce the watering of blueberry tree. Usually watering once a week is enough, and we must pay attention not to ponding.

Blueberry Tree Fertilizer

The fertilization of blueberry tree is mainly concentrated in its growth period. Usually, compound fertilizer should be supplemented every half a month. At the same time, we should spray a little leaf fertilizer. The fertilizer is potassium dihydrogen phosphate, which is easier to absorb. In addition, we must not apply concentrated fertilizer and raw fertilizer to blueberry trees, otherwise it will burn roots in the primary election.
Blueberries can blossom and bear fruit in time only when they grow well. If there is no sufficient water and nutrient supply, resulting in long-term malnutrition, these plants will not bear fruit as scheduled. Therefore, when watering and fertilizing, appropriate water and nutrients should be applied in a small amount.

Blueberry Tree Pruning

Blueberry is a common fruit with high nutritional value, but some people don't know what blueberry tree looks like. Blueberry tree is a small pulp fruit tree. Its plant type is relatively small, and its branches and leaves grow intensively, so it needs to be properly pruned every summer.
When raising blueberry trees, we need to choose a good flower pot, and it is best to choose a clay pot, because the clay pot has very strong air permeability and low price, which is very suitable for planting blueberry trees. Remember not to use a glazed porcelain pot. The air permeability of that porcelain pot is extremely poor, which is very harmful to the growth of plants.
For the propagation mode of blueberry tree, we can use cutting to take down a relatively healthy and vigorous blueberry branch, soak it in rooting water for one hour, and then directly cut it into moist and loose soil and place it in a cool and ventilated place. In about a month, this blueberry branch will grow new roots. After new analysis, we can move the basin for him. When moving the basin, we must pay attention not to damage the roots. It is best to transplant with roots and soil.
In the later maintenance of blueberry trees, we can add some organic manure, such as sheep manure and chicken manure. These two kinds of manure are very good for blueberry trees. They are not only rich in nutrition, but also have a very balanced variety of elements. The fertility is also relatively mild and will not hurt the roots. Blueberry is a plant that likes acidic environment. Blueberry can grow healthily only in acidic soil. The pH value of culture soil is preferably between 4 and 5, which is the most suitable for blueberry growth.

Blueberry Tree Repotting

We generally choose to plant blueberry tree in spring, autumn and winter. Improper management is easy for blueberry tree to suffer from freezing injury. When planting blueberry tree, we fill some wet acid peat soil or pre prepared planting soil in the pit, then plant the seedlings and expand the roots, let the added mixed peat soil surround the seedling roots, and finally cover the soil to be level with the ground.

Blueberry Tree Pest & Disease Control

It should be noted that if the blueberry tree is in the fruit development stage, it is necessary to appropriately reduce the water supply and keep the soil slightly moist. It should also be noted that disease prevention and control. Sometimes improper maintenance will lead to the occurrence of blueberry diseases, such as leaf spot. This leaf spot is mainly manifested in the abnormal color of blueberry branches, and the branch epidermis is covered with reddish brown disease spots. At this time, we should not throw away the blueberry trees, just cut off the infected branches in time, and spray the plants with fungicide, Disinfect and sterilize, and then move the blueberry tree to an indoor ventilated and cool place for maintenance for a while. When new buds grow, move it to an outdoor place for maintenance.
If the blueberry tree is yellowing, it should be that the blueberry is deficient in elements. To solve this problem, we have to adjust the acid content of the blueberry soil and properly irrigate the blueberry. Generally speaking, we can dilute the basin soil with some Jiamei dividends, or mix peat soil with sulfur powder and sprinkle it near the blueberry root system. This will slow down in about 30 days.

Blueberry Tree Cutting Propagation

Blueberry Tree Cutting Propagation is one of the best Blueberry Tree Propagation methods. The planting method of potted blueberry trees is very simple. First of all, the soil should be mixed. Blueberry trees like acidic soil, and they should be soft, breathable and rich in organic matter. Only when blueberries are planted in this soil can the roots be stronger and the plants grow vigorously. As for flowerpots, I suggest using flowerpots with good air permeability. It's best not to use ceramic pots and porcelain pots.

Blueberry Tree Division Propagation

During the maintenance of blueberry trees, if you want blueberries to grow more vigorously, make their branches and leaves grow more robust and blossom and bear fruit, you need Blueberry Tree Division Propagation. Generally, I suggest you use acid fertilizer, because blueberries have shallow root distribution and are very sensitive to water shortage. We can use some nutrient solution for blueberry trees. The nutrient content of liquid fertilizer is very high, which can comprehensively promote the growth of blueberry trees and make them blossom and bear fruit smoothly. However, blueberry trees are "oligotrophic" plants, which do not need much fertilizer and other nutrients. They do not need topdressing often. They can be fertilized once a month or so.

Blueberry Tree Varieties

Blueberry trees are generally divided into three categories: high branch varieties, low branch varieties and medium height blueberry trees.
The tall Blueberry Tree Varieties is about six feet high in warm areas. Low branch blueberries are more cold resistant and planted in temperate regions. So if you live in a really cold area, it's for you. This kind is only more than a foot high, some like wild, the roots grow in parallel and will spread.
Blueberry tree of medium height, generally about 66 cm high, with many fruits.
Today, most farms and gardening shops choose the first blueberry tree, which is also the most common. Therefore, there is almost no need to ask when buying. They are all of this kind. However, there are many varieties of blueberry trees, so there are still many choices. These choices include: cold tolerance, fruit size, taste, fruit month, etc.
However, most blueberry trees need two trees to bear fruit, so at least two or more varieties must be planted to ensure fruit bearing, and the fruit bearing period is long and there are many fruits.
Blueberry tree is also suitable for potting because its plants are small, and the soil of potting is easier to control. In addition, raising the blueberry tree flower bed is also suitable. (Find more healthy fruit here.)

Blueberry Tree Benefits

Blueberries taste super good, sour and sweet, very appetizing, and blueberries are rich in a large number of anthocyanins, vitamins and other elements. Regular consumption is conducive to health, can effectively improve vision, beauty and beauty.

Blueberry tree height

If the blueberry tree is in the wild, the plant height will not be too high, because it is a low shrub. The low bush is only 30-50cm, and the half high bush is relatively high, which can be about 50-100cm. The height of seedlings cultivated by artificial planting is relatively high, but it is generally controlled.

What does a blueberry tree look like?
