How Many Years Until a Potted Blueberry Flowers and Fruits?
Blueberry is also known as bog bilberry, black bean tree, doushi, dragon fruit, getang fruit, etc. It is a perennial low shrub that can be grown in pots or in the ground.So how many years until a potted blueberry flowers and fruits? How should it be cared for?
1. How many years until a potted blueberry flowers and fruits?
After potted blueberries are planted in autumn, they can flower and fruit in small amounts the following year; by the third year they can flower and fruit normally. In about five years they enter the full fruiting period, and with proper care the fruiting period can last as long as 35 years.
2. How should potted blueberries be cared for?
1. Potting soil selection
Blueberries prefer acidic soil, with a pH of 4.5-5.5. For potting, choose loose, breathable soil rich in organic matter; it can be made by mixing aged bark, sawdust, straw and decomposed leaf mold into a potting soil. At the same time, it is recommended to use a well-ventilated pot; never use ceramic or porcelain pots. You can use tile pots or sand pots, and plastic pots are also fine.
2. Light
Light is essential for the growth of blueberries. If light is insufficient for a long time, the plant will produce few flower buds and the fruit quality will be affected. At the same time, proper pruning can be combined to benefit photosynthesis in potted blueberries. For potted blueberries on a balcony, attention should also be paid to ventilation.
3. Temperature
For potted blueberries, temperature is a very important factor in ensuring fruiting. It is necessary to ensure that blueberries undergo dormancy in winter at low temperatures below 7.2°C; the minimum temperature varies by variety. For example, when grown as an ornamental flower, low-temperature restrictions cannot be used.
4. Watering
When watering potted blueberries, attention should be paid to the water source and water quality. Because deep well water usually has a relatively high pH and contains relatively high sodium and calcium, long-term use is not good for the growth of blueberries. Therefore, when irrigating, sulfuric acid can be used to adjust the pH of deep well water to about 4.5-5.5 before watering. Generally, after about 3 waterings, water once with acid water.
5. Fertilizing
Blueberries should not be fertilized frequently. When planting, a certain amount of organic matter can be added to the soil. Later, care should be taken to apply as little phosphorus fertilizer as possible, mainly acid fertilizer.
