Can pine seedling bonsai soil be foamed?

Flowers in flower markets or flower shops are purchased from planting bases, and a small amount of mud blocks that can maintain root growth are wrapped in plastic pots. After buying, the flower shop puts the flowers in the beautiful flowerpots that customers like together with the original plastic pots, so that the roots are not damaged and the flowers are not easy to die.

However, in order to decorate the flowers more beautifully, some flower shops will tear down the original flowerpots, put flowers and trees directly into various beautiful flowerpots, and then fill them with soil, commonly known as "assembled pots". But the original clods were not very big. Those deep and big flowerpots still need a lot of flower soil to fill, and flower soil has to be bought. As a result, foam, waste paper, rope grass and other wastes became substitutes and were put into the bottom of the flowerpot. Florists often only spread some good soil on the top of flowerpots, put in flower roots, put in some nutrient soil, and sprinkle some decorations such as ceramsite and perlite.

Using whitening agent or putting foam, waste paper and other rubbish at the bottom of the pot are important reasons for the short life of potted plants.

"The leaves in the flower market are bright and bright, and they are basically sprayed with whitening agents." Wu Sizheng said that this is equivalent to covering the leaves with a film, which hinders the photosynthesis of plants. The leaves will soon wither and the flowers will naturally not live long.

In addition, the roots of potted flowers are often destroyed. When the roots continue to grow, they will not be able to absorb water and nutrients when they encounter garbage such as foam and waste paper. Use foam as the bottom, because foam is airtight and impermeable, which has little effect on the growth of flowers in the short term, but in the long run, flowers will slowly rot or die due to lack of nutrition.

It is suggested that citizens choose "old pots" when buying potted plants. According to the time of transplanting flowers into flowerpots, the "old pot" is more than two months, while the "new pot" is the opposite.

How to tell whether the basin bottom is filled with soil or foam? First of all, from the weight point of view, "there must be something wrong with the tall potted flowers that a girl can lift."

Secondly, tap the bottom of the flowerpot, the sound is empty, so be alert. When you drag the flowerpot, the broken foam will run out of the air hole.

The flowerpot is easy to fall off when it is transported to the car, and the water is easy to soak into the soil, all of which indicate that there is something wrong with the soil in the flowerpot.

The easiest way is to inspect the goods on site and change the pot.

In addition, when buying potted plants, you should "like the new and hate the old". The soil color of the "old pot" is uniform and dense, and there is no obvious graininess when digging by hand. You can see the roots of flowers from the water outlet at the bottom of the pot.
