lavender blooms

How do I get my lavender bush to produce more blooms? It already makes a few each year, but not as densely or as many as I'd like to see. Is it nutrition? Sun? Water? Pruning? Note: the plant I have is three feet wide and two feet deep. My other one is two feet by two feet. They're on the east side of the house. They get about four hours of direct sunlight a day. I heard somewhere that six or more hours of sunlight is considered "full" sunlight. Any suggestions? I would really like to have more flowers come out!
