The quality of the soil directly affects the growth and development of plants.
This is why even purchased soil should be given attention and its condition should be improved to help the plants.
What to add to purchased soil
Let's start with the fact that it is worth checking the quality of the substrate externally. The soil should be loose and without impurities.

If you notice a sticky or viscous consistency and traces of mold in it, it is better not to use such a primer.
In order for the seeds to germinate better, it is recommended to add additional substances to the soil for seedlings that will increase germination.
These components include:
- vermicompost;
- vermiculite;
- coconut substrate;
- wood ash, etc.
It is believed that compost is one of the most accessible substances that most summer residents and gardeners have on hand.
As for the concentration of additional substances, everything depends on what exactly and how you are going to grow. For example, if the seedlings are to be grown with subsequent picking, 20% of organic additives is enough.
If the seedlings are initially grown in different containers, it is worth adding 30-40% organic matter.
