As a result the soil they frequent tends to be loosened, easy to work and extremely fertile.

The researchers have found that the soils of the forest, for reasons they do not yet know, tend to repel water.

Dark soils tend to absorb more heat, and are therefore preferred.

The soil in the highlands tends to be moderately well drained.

These soils tend to not have a lot of vegetation.

In gardens where the soil tends to be dry, they will do best in shade.

Because of the drainage, the soil tends to be of low fertility.

They should be repotted every other year because their soil tends to sour.

In those regions where rainfall is adequate, the soil tends to be poor, or the weather too cold.

In this case the soil tends to come off in flakes.
