Additionally, why is my giant sequoia turning brown?
Caused by the fungi Kabatina juniperi and Phomopsis juniperovora, juniper twig blight results in wilting and discoloration of sequoia foliage, causing it to turn brown, red or yellow and die back. Tip damage moves backward on the branch and if not pruned, may reach and kill the tree.
