We have a large Norfolk pine tree in our backyard. Its estimated height is 15 -20 ft. and it is backed up to conservation. The fronds are turning brown and have been doing so for the last couple of months. We had a hard winter in 2009 for Tampa and we are now in our rainy season. What can we do to help prevent this brown from continuing further up the tree?
