My Strata is planting a nerw cedar hedge and we are trying to find out how much water the trees will need. They are 6 1/2 feet each and are planted 3 feet a part. Each tree will have it's own drip system and we were considering 1/2 gallons per hour for 2 hours three times per week. Is this enough water are do we need to run the system for two hours each day until they take? Your thoughts would be appreciated....
