The answer really depends upon how long you keep your drip system running. A 2gph emitter will distribute two gallons of water if the system is allowed to run for one hour. The root system of your camellia will be in the top 12-18 inches of soil and radiate out as far as the branch tips. The best way to know how long to run your system is to dig down or prod the soil. You can use a stick or a metal rod and push it into the soil in several places around your camellia. If the soil is moist the rod will be easy to push down. When you meet resistance, the soil is dry. As long as you can push it down into the soil about 2' you are delivering enough water for your shrub.
