What is the growth cycle of blueberries?

The growth cycle of blueberry fruit trees varies with species and regions. The growth cycle of Vaccinium uliginosum in Northeast China is as follows:

Germination in mid-May; From mid-May to late June, leaves and flowers began to bloom; Leaves spread in mid-June, new buds grow and flowers bloom; From late June to early July, the fruit expanded rapidly and began to color, and the new shoots stopped growing; The fruit began to color in mid-July; The fruit ripens from late July to early August; The fruit falls in mid-August; From late August to early September, the leaves began to change color; Deciduous leaves fall from mid-September to 10.

In the Songjiang River area of Changbai Mountain, the phenological period of blueberry is longer than that of Spring Festival Evening 10d. The germination period is in mid-May, the flowering period is from late May to early June, the fruit is colored from late June to early July, and ripens from late July to early August. In addition, the maturity of dwarf blueberry varieties is earlier, and the maturity of semi-tall blueberry varieties is about 10d later than that of dwarf blueberry.

Matters needing attention during blueberry growth:

1, according to its growth cycle, different fertilizers are used. Blueberries don't need much fertilizer. Fertilization is required once before germination 10 day to 15 day. At this time, the fertilizer should be mainly nitrogen fertilizer.

2. Blueberries need to be fertilized at the fruit-setting stage, and the fertilization should be mainly based on nitrogen, phosphorus and potassium. This time is the key period of blueberry growth, so it is necessary to ensure that the fruit cannot be short of fertilizer. Generally, blueberries are fertilized by watering or hole application, because the roots of blueberries are shallow and most of them are distributed within 20 cm of the surface, so don't fertilize blueberries too deeply.

If it is fertilizer, it can be mixed with water and then directly applied to blueberries, but the concentration of fertilizer should also be considered to avoid damaging the roots of blueberries.

3. Top dressing again before blueberry harvest 10 day. At this time, the fertilizers are mainly phosphorus and potassium. The purpose of applying phosphorus and potassium fertilizer is to promote fruit expansion and improve blueberry yield and quality.
