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. ?
After planting blueberry seedlings in a pot, put them indoors to avoid light and put them in a ventilated place for a week. This process is called slow seedling. You can move outside the balcony for normal maintenance after one week. Blueberries like humidity, especially in summer, so they need to be given enough water every day.
Extended data:
Blueberries are mostly cross-pollinated plants, and high-cluster blueberries can get pregnant by self-pollination, but the pregnancy degree is obviously different among different varieties; However, rabbit-eye blueberry and dwarf blueberry are generally self-sterile, so it is necessary to consider multi-variety collocation in production to improve yield.
After fertilization, the ovary of blueberry flower expands rapidly, and the growth tends to stop after about one month. After that, the berries remained green, and the volume increased only slightly. When the berries enter the discoloration stage and coloring stage, the berries grow rapidly, which can increase the fruit diameter by 50%.
After coloring, berries can grow by 20%, and the sweetness and flavor become moderate. The ripening time of fruits on the same ear is different, and the fruits at the top and middle of the ear ripen first, and the ripening time is from June to August.
