Similarly one may ask, what is killing my spruce trees?
Rhizosphaera needle cast disease, caused by a fungal pathogen, can severely impact spruce, killing needles and causing them to drop prematurely. Wet years such as 2017 are great for the fungus, but bad for trees. Blue spruce trees are most commonly and most severely impacted.
Furthermore, why are my spruce trees dying from the bottom up? Water stress – A pine tree dying from bottom up might actually be a pine tree drying from bottom up. Water stress in pines can cause needles to die. Lower branches may die from water stress in order to prolong the life of the rest of the tree. Prevent dead needles on lower pine branches by preventing water stress.
