Planting methods of potted blueberries

Blueberries, also known as blueberries, benedicts, persimmons, etc., are low shrubs of the blueberry genus of the rhododendron family. They are mainly potted in increasingly compact cities with an inch of land, and almost all blueberries are suitable for potted plants. But balcony potted plants should pay attention to choosing the right varieties of height to facilitate the movement of flowerpots. Let's take a look at the planting methods of potted blueberries.

Basin soil allocation

Blueberry can grow healthily in acidic medium, and the pH of cultivated soil is between 4.5 and 5.5, which is the most suitable for blueberry growth. The pH value of garden soil is generally between 6 and 7, and the lowest pH value of acidic soil sold in flower and bird market is between 5.5 and 6. In general, sulfur powder is used to adjust acid in the planting base, adding one gram of sulfur powder per liter of soil can reduce the soil PH value by 1, and some varieties do not require much acidity, but they are not as good as those planted in acidic soil.

adequate manuring

Blueberries disrelish fat and calcium, generally in the initial stage of planting with mature cattle, sheep, rabbit dung or rotten leaf soil can be, disrelish fat but not topdressing, so in the future planting a small amount of topdressing is still necessary, avoid big fat. Nitrogen, phosphorus and potassium compound fertilizer or ammonium sulfate solution with a content of 1:1:1 is generally used. Also pay attention to stay away from things that contain calcium, such as some people often put eggshells in flowerpots.

Timely watering

Blueberry root distribution is shallow, like wetting, timely watering is very necessary. The water source and water quality of blueberry watering should be paid attention to. Deep well water generally has high pH value and high contents of sodium and calcium, and long-term use will affect the growth of blueberry. PH value can be adjusted to 4.5-5.5 with sulfuric acid during irrigation, but acid water should be irrigated again at intervals of 3 times. Proper watering can make blueberries resistant to high temperature and safely spend the summer.

Illumination control

The demand for light of blueberry is the same as that of other plants. Compared with the same variety, if the light intensity is not enough, there will be fewer flower buds and lower fruit quality. For orchards with high cultivation density, proper pruning is conducive to photosynthesis. For the balcony terrace family, the light management of blueberries is simpler than the orchard, but should pay attention to ventilation.

Cold prevention management

Blueberry dwarf bushes and half-height bushes have strong cold resistance, but due to different low temperatures in different places, freezing injury still occurs in extreme weather, the most important of which is frost injury at the ends of branches and flower buds overwintering in the open air, or even the whole plant is frozen to death. Therefore, blueberry cultivation and overwintering protection are also important measures to increase yield in cold areas.
