I have 4 large redwoods I planted 4 years ago. Three of the four are
growing
Beautifully.The 4th and largest has developed a problem over the past
11-18
months with browning limbs it has slowly spread over the entire
tree.The needles and entire branch slowly die. The trees are all over
25' and have grown according to schedule. (5 feet a year)The tree in
question is still growing and continues to turn out healthy limbs and
is very green at the top. They are on a drip system. I live in
Northern California (Western gardens zone 14)I can send pictures if
you would like. The other three trees are perfect.
Please help!
