What can ten centimeters of soil do? The director told you that growing vegetables on the balcony is enough.

Many novice balcony growers will wonder why their own vegetables are not only small, but also not high in yield.

In fact, a very important reason is that it is not used in the right way. If the soil is not used well, the vegetables will not be able to get sufficient nutrients, and of course they will not grow as expected.

In this article, the director would like to share the question about how to choose the soil for growing vegetables on the balcony.

Direct purchase of cultivated soil

When growing vegetables on the balcony, the simplest and direct choice is to go to the market to buy prepared cultivation soil. This kind of soil has good water retention, permeability and ventilation, and its pH is moderate.

However, there are many kinds of cultivated soil due to different preparations, so you should choose carefully when purchasing.

Generally speaking, the quality is proportional to the price. For example, the quality of the culture soil with high content such as immature rotten leaf soil and dust is relatively poor, so the price is often cheaper.

The director suggested: pay attention, it is not appropriate to buy overweight soil, because the weight indicates that the soil particles are very small, the ventilation and drainage of this kind of soil are relatively poor.

Prepare one's own culture soil

Although the purchased culture soil can be used directly, it is also a good choice to prepare the culture soil yourself.

It can not only let you enjoy the fun of doing it yourself, but also do it with your children, and it can also provide children with a good opportunity to get close to nature.

The director recommends a good method for you.

"skillful preparation of soil"

1. First dig up some garden soil in the garden near your home

two。 Then go to the market to buy some humus soil.

3. According to the actual needs, the two can be mixed in a certain proportion, and generally speaking, they can be prepared according to the proportion of 2 ∶ 1.

The director suggested that humus soil is rich in organic nutrients, generally free of bacteria and eggs, and has good fertility. The soil mixed with general soil is suitable for the growth of most vegetables.

However, there is one thing we need to pay special attention to when preparing our own cultivated soil, that is, the acidity and alkalinity of the soil.

Most vegetables prefer weakly acidic and neutral soils, but some vegetables prefer alkaline or acidic soils.

Therefore, when preparing the culture soil, we should adjust the acidity and alkalinity of the soil according to the preference of vegetables.

If the soil acidity is too strong, you can add some limestone powder to neutralize, if the soil alkalinity is too high, you can add natural sulfur mineral powder to adjust.

The acidity and alkalinity of the soil can be measured by pH test paper or by soil acidity meter.

PH value is a measure of acidity and alkalinity, 7 is neutral, less than 7 is acidic, the smaller the value is, the stronger the acidity is, the higher the value is alkaline, the higher the value is, the stronger the alkalinity is.

The director usually prepares the culture soil in a larger plastic basin, and the soil accounts for half of the container. The prepared soil is of moderate quality, neither sticky nor hard, so it is most suitable for growing vegetables.

The director recommends a good method for you.

"skillful use of weathered soil"

When growing vegetables, it is best to spread a layer of weathered soil at the bottom of the container before putting the culture soil into the container, which is more conducive to drainage.

Weathered soil can be bought in the market, according to the particle size is divided into small, medium and large particles, can be selected according to the needs. If you don't want to buy weathered soil, you can also use some small stones or large grains of sand instead.

In addition, when preparing the culture soil, we can also make some reasonable allocation according to the needs of vegetables to the soil, so as to achieve the purpose of improving the soil.

Generally speaking, the main materials that can be used to improve soil are perlite, vermiculite and so on.

The proper addition of perlite to the soil can increase the soil voids, thus improving the ventilation and drainage.

Vermiculite has good light transmittance and moisture retention, which is suitable for those seeds which are small and do not need to be covered with soil after sowing. After sowing such seeds, covering the soil surface with a layer of vermiculite can prevent the soil surface from being air-dried and the seeds from being destroyed.

To sum up, although different plants have different needs for nutrients and soil acidity and alkalinity, the following principles should be followed when preparing cultivated soil:

-looseness

-good ventilation and drainage

-No germs or eggs.

-sift out the grass roots and other sundries

It has been exposed to the sun or heated and steamed for disinfection.

Finally, the director would like to give us some practical information:

Taiwan friends should put it away. If you judge that there is no problem with the light, temperature, environment, watering and fertilization on the balcony, but your vegetables still do not grow well, you need to check whether the soil properties are not suitable for your dishes.

I don't know if what the station director said was clear and detailed. For those Taiwanese who do not understand it, the director has written a hidden poem for you. It may not be well written, but it can help you find the director.
