1. Variety selection

Some blueberries can pollinate themselves, while other blueberries need to be equipped with pollination trees to hang the fruits. Rabbiteye blueberries, for example, require pollinating trees. For potted blueberry trees, attention must be paid to the selection of varieties such as South China potted plants. The best varieties to choose are Sharpland and Avon Blue. These varieties can pollinate on their own or in home pots.

2. Pot soil preparation

Blueberries prefer acidic soil with a pH value of 4.5-5.5. When potting, you should pay attention to choosing loose and breathable soil rich in organic matter. It can be mixed with aged bark, sawdust, straw and rotten leaf soil to make potting soil. At the same time, it is recommended to use flower pots with good ventilation. Never use pottery or porcelain pots. You can use tile pots or sand pots, or plastic pots.

3. Watering issues and climate

Potted blueberries are a very important factor in ensuring results. It is necessary to ensure that blueberries can withstand low-temperature dormancy below 7.2°C in winter. The minimum temperature varies with varieties. For example, as a flower ornamental, low temperature restrictions cannot be used. Blueberries have shallow root systems and are sensitive to lack of water. Potting soil should always be kept moist without water accumulation, as blueberries vary in different growing seasons. During the vegetative growth stage, optimal moisture conditions can be maintained to increase plant strength. During the fruit development stage and before fruit maturity, water supply must be appropriately reduced to prevent excessive vegetative growth from competing with the fruit for nutrients. After the fruit is harvested, the optimal water supply should be restored to promote vegetative growth. From autumn to late autumn, reduce water supply to facilitate timely dormancy.
