The latest planting methods of potted blueberries

Blueberry, also known as blue plum, toots, persimmon, etc., is a low shrub of Vaccinium rhododendron, mainly potted in more and more compact cities, and almost all blueberries are suitable for potted plants, but balcony potted plants should pay attention to selecting suitable varieties of high and short, so as to facilitate the movement of flowerpots. Let's take a look at the planting methods of potted blueberries together!

basin soil allocation

Blueberries can grow healthily in acidic medium, and the pH value of the cultivation soil between 4.5 and 5.5 is most suitable for blueberry growth. The pH value of garden soil is generally between 6 and 7, even if the acidic soil sold in the flower and bird market has a pH value of 5.5 to 6 at the lowest. In general, sulfur powder is used to adjust acid in planting bases. Adding one gram of sulfur powder per liter of soil can reduce the pH value of soil by 1. Some varieties have little requirement for acid, but they are not as good as those planted in acidic soil.

rational fertilization

Blueberry is too fat and too calcium. In the early stage of planting, it is generally added with decomposed cow, sheep and rabbit dung or rotten leaf soil. It is too fat but not topdressing. Therefore, a small amount of topdressing is still necessary in the later planting. Avoid big fertilizer. Generally used is the content of 1:1:1 nitrogen phosphorus potassium type compound fertilizer or ammonium sulfate 1:2000 times solution. Also pay attention to stay away from calcium-containing things, such as some people often put egg shells into flowerpots.

timely watering

Blueberry root system distribution shallow, like wet, timely watering is very necessary. Blueberry watering needs to pay attention to the water source and water quality, deep well water generally high pH value and high sodium and calcium content, long-term use will affect the growth of blueberries, can be used in irrigation with sulfuric acid to adjust the pH value to 4.5~5.5 or so, but should be about 3 times irrigation and then pour acid water. Proper watering can make blueberries resistant to high temperatures and safe for summer.

lighting control

Blueberry's demand for light is the same as other plants, it is essential, in contrast to the same variety, if the light intensity is not enough, the flower buds will be less, the fruit quality will be reduced, for the orchard with too high cultivation density, proper pruning, conducive to photosynthesis. For the balcony family, blueberry light management is simpler than orchard, but attention should be paid to ventilation.

cold-proof management

The cold resistance of blueberry short clump and half-tall clump is stronger, but due to different low temperatures and extreme weather, freezing injury still occurs, among which the most important is the freezing injury of the end of the overwintering branch and flower bud, even the whole plant. Therefore, blueberry cultivation and overwintering protection in cold areas are also important measures to improve yield.
