1. Maintenance location
Blueberry is a fruit that likes light very much. It can tolerate semi-cloudy environment, but if you want it to bear fruit, you should put it in a place where there is more than 6 hours of direct light every day.
Potted blueberries need a bigger container, which is a shrub fruit. The flowerpot is too small to grow blueberries.
Pay attention to watering
When there is little rain, the blueberries raised outdoors should be watered regularly, preferably when it rains. Friends in the north should avoid watering directly with tap water, otherwise the soil will be alkaline, and blueberries in alkaline soil will turn yellow, which will affect flowering and fruiting. In order to keep the soil slightly acidic, it is usually possible to store some rainwater in containers at home.
3. Land
The maintenance of blueberries must use slightly acidic soil, the pH value is 4.0~5.5, and the drainage must be guaranteed. However, blueberry likes water, so it is necessary to add some peat soil or compost soil to the soil properly, which can increase the acidity of the soil and improve the water retention of the soil.
4. When will it be planted
Blueberries are generally planted by buying bare-rooted shrubs directly in the market or online, which is most suitable for winter cultivation. It doesn't matter if blueberries are planted in potted plants all the year round. Bare-rooted blueberries can be watered with some rooting solution for the first time to promote rooting and germination, and must be watered after planting.
plant
If blueberries are planted and maintained on the ground, they need proper spacing. One blueberry can be planted per meter. Some blueberries are self-pollinated, and these varieties can pollinate themselves. If there are other varieties nearby, their output will be greatly improved. You'd better raise more blueberries at home.
prune
Planting blueberries requires proper pruning, especially potted blueberries. If you see blueberries blooming in the first year, please be sure to cut off all their flowers. The first year will be fruitless. Even if there is, its fruit will be too small to eat. I will cut off the flowers that bloom for the first time at home.
Pruning can be done properly after each fruiting, so as to maintain a good plant type and promote branching, which is beneficial to flowering and bearing more fruits.
7. Preventive measures
It is best to cover blueberries with proper media, and cover them with a layer of sawdust or peat soil with a thickness of 4~ 10 cm every year, which is helpful to regulate moisture and prevent weeds from growing.
If your blueberries begin to bear fruit, you'd better protect them with things like mesh mosquito nets to avoid being eaten by birds.
8. Fertilizer
The maintenance of blueberries requires regular supply of some acidic fertilizers to avoid soil alkalescence, and regular supply of some ferrous sulfate. It is best to choose some varieties that bloom in spring for potted blueberries, and supplement fertilizers appropriately when blueberries have just bred buds.
9. All kinds of blueberries
If you are in a warm area, it is suggested that you use tall plants that can grow for many years to raise rabbit-eye blueberries. They are also more adaptable to the environment and can tolerate harsh soil and water conditions.
If you are in a cold place in the north, it is suggested that you raise some blueberries with higher plants and plant more than two blueberries for cross pollination.
10. Pests and diseases
The most common disease of blueberry maintenance is powdery mildew. This fungal disease can easily lead to yellowing of leaves, which can seriously lead to blueness of blueberries, and improper treatment will reduce the yield of blueberries.
Once you see that blueberries are infected with fungal diseases, you must remove them in time. You can prepare some pesticides at home and spray them in time when you find pests. The common pests of blueberry are blueberry borers, which are easy to cause dry leaves and wilting branches. Also pay attention to the prevention and control of cherry sword moth and weevil.
