Precautions for indoor potted plants are as follows:

1. The soil where blueberries are planted should be breathable and permeable. When you grow blueberries at home, you can mix humus with river sand to increase air permeability. Blueberries belong to Ericaceae, so they like sour taste. When preparing soil, we must consider the acidic conditions of nutrient soil, and some yellow soil is more conducive to good growth.

2. Light is very important for the growth of blueberries. If the light is insufficient for a long time, it will lead to the decrease of flower buds and affect the quality of fruit. At the same time, it can be combined with proper pruning, which is beneficial to the photosynthesis of potted blueberries. Potted blueberries on the balcony should also be ventilated.

3. Blueberries like fertile environment, and they should be supplemented with a small amount of nutrition many times during family maintenance. However, blueberries are very afraid of calcium fertilizer. If you don't supplement a lot of calcium, it will lead to physiological diseases and fruit cracking.

Cultivation techniques of blueberry

It is best to choose clay pots for planting blueberries. Pottery pots are breathable and cheap, but they are not very beautiful. If you can't buy pottery 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 pot, for 2-3-year-old seedlings, choose a pot with a diameter of 25-30 cm, and then change it into a big pot when it grows up. Mature plants of 4 ~ 5 years, of course, the bigger the better.

Blueberries can grow healthily in acidic medium, and the pH value of cultivated soil is between 4 and 5, which is most suitable for blueberry growth. This problem has troubled many blueberry lovers, because the pH value of pastoral soil is generally between 6 and 7, and even the acid soil sold in the flower and bird market has a minimum pH value of between 5.5 and 6.
