Manifestations of Insufficient Cold Storage in Blueberries | Blossoming without Bearing Fruit
This article introduces you to the common knowledge of growing blueberries, including the manifestations of insufficient cold storage in blueberries | blossoming without bearing fruit. Next, the editor will provide an introduction.
Blueberries require a certain amount of cold storage. Some gardening enthusiasts want to know the manifestations of insufficient cold storage in blueberries. If the cold storage is inadequate, blueberries can still bloom normally (or sprout late in spring), but they will not bear fruit.
The so-called cold storage refers to the amount of time blueberries need to be exposed to temperatures below 7°C, generally accumulating 800 to 1200 hours to bloom and bear fruit normally. The specific time varies depending on the variety. Therefore, growing blueberries on balconies in the Jiangnan region does not require moving them indoors during winter. Consequently, potted blueberries should not be kept in rooms with heating or insulation functions during winter, but can be placed in courtyards, garages, warehouses, or shaded balconies, provided that the temperature is below 7.2°C for most of the time.
When the temperature is below 8°C, the root growth of blueberries almost stops. When the soil temperature reaches 9°C, the root growth almost stops.
When the soil temperature reaches 14°C to 18°C, the peak of blueberry root growth occurs.
The timing of cold protection should be appropriate and not too early. It is best when the highest outside temperature stabilizes at 5°C or below. If done too early, it can cause the buds to be overheated (commonly known as "stifling the buds").
The cold requirement of northern highbush blueberries needs to accumulate 800 to 1200 hours of low temperatures between 0-7°C.
The above is a comprehensive introduction to the manifestations of insufficient cold storage in blueberries | blossoming without bearing fruit, hoping to provide green plant enthusiasts with some knowledge about green plants.
