16 (6Ft) container grown Cyprtomeria Yoshino, professionally planted in full sun Oct. 29th, 2005 are under my care. I've read all previous posts and still have questions. What is the proper care for these trees, in the foothills of North Carolina, border line zones 7-8? I too was told to water (pressure as if I forgot to turn off the hose) 10-15 minutes per tree every 2-3 days. More often for a mild winter and less often when it rained regualry. One of the trees is complete brown, except for some green at the bottom. Do I cut off all of the limbs in hope that new branches will form? Should I continue to water this tree hoping to regain life? When I called the nursery they told me I over-watered. My remaining trees grew about 1ft. since planting, but now they are turning brown on the tops of the "leaves" and are full green underneath. Even some of the new growth is turning brown on the tips. Are these at risk or being burned from the sun? I saw a green bug the size of a large beetle on my tree. Is this bug causing damage? What is a rust problem? Do I have a fungus and should I treat? If yes, with what? Should I cut off the brown spots and treat with Clorox? If yes, what is the percentage of water, if any, in the solution? What is the best time of day to water? Is there a cut-off time before nightfall? Our temps can range from 30's at night to 60's mid-day. When is it too cold to water to avoid root damage? When can I fertilize the tree and will this help them regain life? Our temps become milder in March so I pray that they will last until them. I was told March/April I could fertilize, but I'm not sure if I trust these instructions. Photo was taken November 19th. I don't have a current picture but will get one if absolutely needed for your response. HELP!
