Why Professionals Change Soil Mixes

At garden centers and nurseries,
they sometimes grow the same plants in different soil mixes.

The reason for this is that
there is no single environment in which plants grow.

For example,

when they are small seedlings
→ soil that retains water easily

once they have grown large
→ soil with high drainage

In this way,
the role of the soil changes depending on the growth stage.

Also,

・Regional climate
・Temperature
・Sunlight
・Management methods

The optimal soil also changes based on these factors.

That is why professionals
do not insist that "this soil is the only correct one,"

but instead adjust the soil to suit the plant and its environment.
