Remove the cold proof soil in time

Timely removal of cold proof soil can make blueberries sprout and germinate in time, and the plants grow healthily. If the cold proofs are removed too early, the ground temperature is low at this time, coupled with the strong wind in spring, the plant root system can not absorb water and nutrients, and the germinated flower buds will gradually dry out and die after expansion, which is also vulnerable to late frost. The removal time is too late, because the ground temperature rises rapidly in spring, the temperature in the mound rises and the humidity is high. In this case, the flower buds will germinate in the soil, and even lead to the yellowing of the tender buds and shoots. After being unearthed, the young stems and leaves can not stand the wind and the sun

Water the green water in time

The weather in spring is dry and windy. After removing the cold proof soil, it is the key period for blueberry germination and rejuvenation. Watering the plants with sufficient rejuvenation water in time can not only ensure the normal germination and growth of blueberries, but also prevent blueberry branches from drying out

Reasonable pruning of trees

For 2-3-year-old blueberry saplings, erasing all flower buds during pruning will help to promote root development, crown expansion and increase the number of branches, and lay a good foundation for early high yield

For 4-5-year-old young trees, the crown shall be expanded, the flowers and fruits shall be properly thinned, and the damaged and diseased branches shall be cut off at the same time

Since the inner bore of blueberry trees over 6-7 years old is often easy to be covered, the main purpose of pruning at this time is to improve the light conditions, cut off the over dense branches, overlapping branches, Cross branches, thin and weak branches and sick branches, and retract and renew them in time. The weak branches can be pruned by smearing flower buds, which can promote their growth and health
