I had planted a dozen Thuja Green Giants 3yrs ago along the property border line in urban setting thinking they would be elegant screening for my backyard. They sustained two winters and one summer (2010). They hardly grew 2ft. But last summer (2011) they all perished due the the N Texas heat. I do not want to take chances again with these trees.
From my backyard, I can see the interstate freeway traffic. I am considering Nellie R Stevens holly for screening and want them to be at least 8ft tall in 2 yrs. I may need to plant them in a row along the fence 85ft long. I guess I need at least 9 such trees. Can someone from the forum suggest the best time to plant them and where I can buy them (at least 4 ft tall) in N TX area?
