Is loess or black soil better for growing flowers?

Recently, a flower lover noticed that the leaves of the plants at home had wilted. After looking into many possible causes, they finally discovered it was because they had mixed a bit of loess into the potting soil. So which soil is really best for growing flowers, loess or black soil?

Loess is the light yellow or yellowish-brown soil we usually see. It forms in dry environments, and once it is soaked with water, it clumps together and becomes impermeable to air.

Therefore, loess is generally not suitable for potted plants. For planting in the ground, it is still acceptable. This is because when loess is put into a flower pot, the pot's size is limited, and once it is soaked with water, it becomes impermeable to air and settles, which then causes a series of problems for the plants.

Black soil, on the other hand, is formed from the decay of a range of natural materials. It is especially rich in humus and abundant in nutrients, and it is extremely strong in both air permeability and water retention.

Generally, black soil or garden soil is the most suitable for growing flowers. Black soil is especially rich in fertility and the like, and is suitable for the growth of all flowers.

Of course, when growing flowers, leaf mold can also be used.

Leaf mold, as the name suggests, is fertile soil formed from leaves that fall to the ground and are then decomposed by microorganisms in the soil.

The biggest characteristic of leaf mold is that it is loose and air-permeable, with a good controlling effect on water and nutrients, retaining both water and nutrients. Not only that, because it has many pores, when it is mixed with other soils it can increase the looseness of the soil and make it less prone to compaction.

Moreover, its organic matter and other nutrient elements are especially rich, which is especially good for plant growth and can make plants grow especially vigorously.
