On March this year, I bought 10 Emerald Green Arborvitae ( 1 gallon). I put them in backyard, fully under the sun. they grow well until recently some of them became yellow color. I water them each using hose for 1 minutes, it did not turn the color to green.. Do I water it too much?

The poor color is an indication of root stress. I'd water as usual then wait 3-4 days and dig down to see how moist the soil still is. If it is moist 2-3" beneath the soil surface, you won't need to water for another 3-4 days. If it is on the dry side, go ahead and water. Most landscape trees and shrubs need at least one inch of water per week, especially during the spring and summer periods of fast growth so be sure to water deeply once a week. Aside from watering issues, you might want to give them each a little Ironite or other supplemental iron. This should green them up for you.
