Succulents that are grown in the ground get their nutrients from the surrounding soil. Micro-organisms in the soil are constantly breaking down organic matter, which adds nutrients.
However, the soil in pots doesn’t undergo this process and plants will need supplemental nutrients in the form of fertilizer.
This is even true of cactus and other succulents.
