How long does it take Zoysia grass plugs to fill in?

Can you tell me, approximately how long does it take for Zoysia grass plugs to fully fill in and create a dense, lush lawn? I'm curious about the timeline from planting the plugs to achieving a fully established and visually appealing grass cover. Are there any factors that can affect this growth process, such as soil quality, irrigation, or weather conditions? Understanding this information will help me plan my landscaping project more effectively.
