Growing flowers and matching soil is very simple, as long as the pot soil produced by these four points can rub against each other for long.

This is the 921st 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"

Yesterday, the blue demon said that potted flowers and potted soil are the two most commonly used substrates, but in addition to these two main growth substrates, we also need to match some particles that can increase air permeability, so that we can make a perfect, loose and breathable potted soil.

For the particle matrix used to increase the permeability of basin soil, perlite and vermiculite are most commonly used. For more viscous basin soil, we usually use ceramsite to increase its air permeability. So what are the common characteristics and differences among the three? 1. Perlite:

Perlite is a kind of white granular material with honeycomb structure made of perlite ore after preheating and instantaneous high temperature roasting expansion. It has good air permeability and water permeability. Perlite is very light and is often used in horticulture to mix with substrates such as peat to grow plants. Perlite is easily crushed. Therefore, in the selection, we should try to choose large-grained perlite. 2. Vermiculite:

Vermiculite is a kind of mineral, non-fertilizer, non-toxic, good water retention and air permeability, and is also a commonly used substrate for horticultural cultivation. Vermiculite texture is also very light, water absorption and water retention is very good, but also relatively fragile, it is recommended to use large particles of vermiculite, the general diameter of 3-8mm is better. 3. Ceramsite:

Ceramsite has been used in horticulture for a long time, and many people who grow flowers with garden soil in the countryside will use ceramsite to increase the permeability of the basin soil. Now most of them are used to make shop surfaces, covering the surface of flowerpots to cover up the potted soil, which is more beautiful and clean. Compared with perlite and vermiculite, ceramsite is hard and less fragile, but it has larger particles and is not used to mix soil in modern horticulture.

Because modern times are mostly cultivated with peat, the combination of peat and ceramsite will be relatively strange. So when we mix basin soil, we should grasp the proportion of each kind of matrix? In fact, the comparison of potted soil is not fixed, and the substrate used is not fixed.

We only need to master a general principle of soil distribution. Potted flowers, we all require potted soil to have: loose, breathable, water conservation, fertilizer conservation at the same time these four characteristics are basically in line with the requirements of potted soil. You don't need to worry about whether to use peat, coconut brick, garden soil or rotten leaf soil. You can use whatever you have.

Relatively speaking, the soil of herbaceous flowers requires that the soil is more loose and breathable, while the soil of target flowers can be slightly heavier. In general, the blue demon recommends that when mixing soil, do fiber: particulate matter: organic matter = 1:1:1 according to this ratio, it can be said that 80% of the flowers are fine.

On the pot soil, a simple statement you as long as you can understand and use the blue demon said: so that fiber: particulate matter: organic matter = 1:1:1 can be ready.
