Do not use this kind of soil to grow flowers. It is easy to rot the roots. Please pay attention to it.

This is the 917th day of the blue demon's daily original article.

Excerpts from the series of "changing from zero foundation to master flower grower in 30 days"

When it comes to potted soil, many people have a headache and don't know how to match it, and the price of buying special soil is very expensive, so many flower friends choose general nutrient soil.

In fact, the general-purpose nutrient soil is also very good, but now the composition of the general-purpose nutrient soil on the market is too complex, do not know what ingredients are mixed, it looks very loose, but the water permeability is very poor.

With regard to the general nutrient soil, the blue demon also used the general nutrition soil bought online a few years ago, but it was found that the pot wilted to death soon after changing the pot with the general nutrition soil. If you dig it out, it looks like rotten roots. Before also met several flower friends, consult with the blue demon, how to change the pot after the flowers slowly died, after inquiry, learned that they are also used in general nutrition soil.

Flower friends who have used general nutrient soil will carefully find that this kind of soil will not dry for a long time after watering. This is the relationship of poor air permeability. When the soil is in a humid environment for a long time, it is easy to cause plant roots to rot.

The above text, I think blue demon will offend a large number of people, but there is no way, in order to avoid novice flower friends less detours, blue demon offends some people does not matter, at most is to be sprayed a few words, only hope blue demon text, can really help you! So the general nutrient soil can not be used, what should be used?

What should be used for potted soil? This seems to be a very complicated problem, but it is actually very simple. As long as we understand the matrix characteristics of commonly used pot soil, it will be easy to prepare pot soil suitable for our pot growth. We buy potted plants in the flower market, the potted soil is often peat and coconut brick soil, then today the blue demon will talk about these two commonly used substrates. About peat soil

Peat soil is a kind of cultivation substrate widely used in flower potted plants. it is deposited by some rivers and lakes in low plains and intermountain valleys due to long-term stagnant water and dense aquatic vegetation. soil in which a large number of insufficiently decomposed plant residues accumulate and form peat layers. Peat has good air permeability and the ability to retain water and fertilizer, and the texture is light.

Peat is divided into imported peat and northeast peat. In fact, the two are the same thing, but the quality is different. Compared with the imported peat soil, the air permeability and the ability of water and fertilizer conservation of northeast peat are much worse. But northeast peat is cheap.

Therefore, northeast peat is widely used in nursery breeding. We flower friends grow on the balcony at home, we can also use northeast peat, but it is recommended to use imported peat, peat will be much cleaner, northeast peat has a lot of dust, relatively dirty. Peat is a non-renewable resource, so now many people propose to use coconut bricks instead of peat soil. So what is a coconut brick?

In fact, coconut brick is the shell of coconut brick after processing, generally pressed into a brick shape, soaked in water when used, and used after expansion. The water retention of coconut brick is very good, although many people are using it now, but blue demon suggests that you should use coconut brick as little as possible when mixing basin soil, because the water retention capacity of coconut brick is too strong, it will make your basin soil not dry for a long time, and it will be wet for a long time. The bottom of the coconut brick will be moldy.

Although the introduction of the coconut brick says that it will not be moldy, the fact is that the coconut brick will be moldy, the blue demon himself has been useful, and many flower friends who have used the coconut brick have the same feedback. For novice flower friends, can not control their own hands, or can not grasp the degree of watering, it is best not to use coconut bricks or less.

When mixing basin soil, in addition to these two commonly used cultivation substrates, we also need to add some breathable substances to increase the permeability of basin soil, so what should be added?
