How to grow blueberries in balcony pots

illumination

Light is essential for the growth of blueberries. If there is insufficient light for a long time, the plant will have fewer flower buds, affecting the quality of the fruit. At the same time, proper pruning can be combined to promote the photosynthesis of potted blueberries. For blueberries planted in balcony pots, you should also pay attention to ventilation.

Watering

The roots of blueberries are shallow and they 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 levels of sodium and calcium, long-term use is not conducive to the growth of blueberries. Therefore, you can use sulfuric acid to adjust the pH value of deep well water to about 4.5-5.5 before watering. Generally, you should water with acid water after about 3 waterings.

Pot soil

Blueberries grow best in acidic media, and the pH value of the culture soil is generally best between 4.5-5.5.

Fertilization

Please note that blueberries are intolerant of fertilizer and calcium. Generally, you can use leaf mold or add some decomposed cow, sheep, or rabbit manure in the early stages of blueberry planting. A small amount of topdressing will also be required during the subsequent planting process, but avoid applying too much fertilizer. Generally, you can choose a nitrogen, phosphorus and potassium compound fertilizer with a content of 1:1:1 or a 1:2000 times solution of ammonium sulfate. Remember to stay away from things containing calcium. For example, some flower lovers often like to place egg shells in flower pots at random, which is not conducive to the growth of blueberry plants.
