Hi. I have a 10 foot weeping cypress that we transplanted 14 months ago. After some initial shock the tree has been doing great. However, in the last couple of weeks, I've noticed several brown areas and there are more every day. I've been watering it twice a week - dripping hose for 1 hour - so I don't think it's dry. I live in Narragansett, RI. Can you advise please? Thank you.
