How can I plant the clods of ground cover plants?

Prepare the ground with standard soil, if possible slightly burying the pipes for drip irrigation to a 20-30 cm distance from each other. However, you can irrigate the ground cover plants even with a normal irrigation system by sprinkling germination.
At this point just put the clods one after the other side by side over the soft ground. Irrigate once a day for some days to promote rapid rooting.
