Because the desert is too arid for them to survive.
Plants must compete for water resources in the desert so grow at a distance from their neighbors so that they will be able to absorb enough water to survive.
The desert receives little rainfall and plants have to compete for what little falls. They grow a distance for their neighbors to avoid competition and have a better chance of surviving.

Succulent plants and cacti need to store as much water whenever the rain should happen to fall. As the rain may be far between in desert areas, storing water is vital to help the plants to survive.
There is limited water available in the deserts so plants tend to space themselves to avoid competition from other plants.
In a desert, what little rain there may be is stored in the stems and leaves (succulents), or in the swollen body (cacti). Desert plants may also send down deep roots to seek out any ground water far below.
