Emerald Green Arborvitae Look Dry And Are Starting To Yellow

Question From: Erie, Pennsylvania, United States
Q: hi,i planted 2 emerald green arborvitae this summer as replacements for 2 that started dying. the new ones did well all summer.now suddenly,one of them looks dry & is starting to yellow on the outside of the plant.actually, the whole bush looks like its going bad.i tried digging the plant out & raising the root ball ( the bushes are sitting at the base of an incline of my yard) because I thought they might be getting too much water.it hasn't worked.....yet. now today,i noticed the other one is starting to do the same. any ideas? thanks

A: Proper watering is key to success. These trees need a minimum of 10 gallons of water a week and it should be applied directly to the rootball. The root ball will dry out quickly if it goes without water for a week. Check the soil in the rootball. Best And Happy Yardening, Nancy.
