Is my tree dying if it has yellow leaves?

Not necessarily. It is often a sign that the tree is struggling with heat or water, which can be corrected.

Should I fertilize immediately?

Only if you have confirmed a nutrient deficiency through a soil test. Over fertilizing can actually stress the tree further.

Nutrient Deficiency
Possible
How to tell: Leaves turn yellow while the veins remain green. This often happens in compacted or poor soil.
What to do: Test your soil to see if it lacks essential nutrients. Apply a slow release fertilizer in early spring if a deficiency is confirmed.
