The role of vermiculite and how to mix soil

1. Function

1. Breathable and water-permeable: Vermiculite has good air permeability and water-permeability. It can make the soil loose and breathable, increase the loosening effect, and allow the roots to breathe normally inside, avoiding stuffiness and airtightness, which can help the plants grow healthily. The water permeability effect is also outstanding, which can enable water to be discharged normally, avoiding serious problems of water accumulation, reducing the possibility of root rot and maintaining normal growth of plants.

2. Seedling cuttings: Vermiculite can also be used for seedling cuttings. You can put a wet paper towel on the vermiculite, and then put seeds on it for seedling growth. You can also insert the processed branches into the cuttings to promote rooting.

3. Prevent insects: When growing flowers, you can disinfect the soil and then spread vermiculite on the soil surface to prevent insects from drilling in and laying eggs, which has an insect-proof effect.

4. Decorative effect: Vermiculite has a variety of colors. You can sprinkle a layer of vermiculite on the surface of small potted plants, which can play a decorative role and look more beautiful.

2. How to prepare soil

When using vermiculite to grow flowers, you cannot use only vermiculite. It does not contain nutrients and cannot provide nutrients for plant growth, which will cause poor plant growth. The general soil mix can be made by mixing vermiculite, perlite and peat soil in a ratio of 1:1:3. The soil mix is ​​not fixed and the materials and proportions can be adjusted according to the specific situation.
