How to grow blueberries in balcony pots

Light

Light is important for the growth of blueberries. Indispensable, if there is insufficient light for a long time, it will lead to fewer flower buds on the plant and affect the fruit quality. At the same time, it can be combined with appropriate pruning to facilitate the photosynthesis of potted blueberries. For potted blueberries on the balcony, ventilation should also be paid attention to.

Water

Blueberries have shallow root systems and like moisture, so timely watering is extremely important. When watering potted blueberries, you need to pay attention to the water source and water quality. Because the pH value of deep well water is usually high and it contains high sodium and calcium, long-term use is not conducive to the growth of blueberries. Therefore, you can use sulfuric acid when filling water. The pH value of deep well water should be adjusted to about 4.5-5.5 before watering. Generally, the water should be watered about 3 times and then acidic water should be watered once.

Pot soil

Blueberries are suitable for growth In acidic media, the pH value of culture soil is generally between 4.5 and 5.5.

Fertilization

Note that blueberries have the characteristics of being too fertile and too weak for calcium. Generally, in the early stages of blueberry planting, you can use humus soil or add some decomposed cow, sheep, and rabbit manure. And a small amount of top dressing is needed during the subsequent planting process, but large amounts of fertilizer should be avoided. Generally, you can choose a nitrogen, phosphorus and potassium compound fertilizer with a content of 1:1:1 or a 1:2000 solution of ammonium sulfate. Remember to stay away from things containing calcium. For example, some flower lovers often like to place egg shells randomly in flower pots, which is not conducive to the growth of blueberry plants.
