Help! Are my Arborvitae trees dying?
Help! We live in CO and planted a row of 6 arborvitae trees last Spring. They were doing well and staying green, and were watered by a drip line on a regular basis until the first frost. When winter hit, we were careful to tie the branches together and bang off heavy snow so that the branches wouldn't freeze and break off. Now Spring is upon us, and the branches are browning. Although the pictures might seem as though the branches are yellow, they are actually more brown in color. We are watering them with a good 10 minute soak every 4-5 days or so, so we don't think it is a water issue. Also, some of the branches are blackening at the tips - is this due to some kind of fungus? Any advice is appreciated - please help us revive our trees! Thanks!
