Fertilizer for spruce

Asked July 13, 2020, 9:30 AM EDT

Thus young spruce was covered with new growth in the Spring. every branch had light green new growth. Should I be fertilizing Now? Or in the Fall? What type? Do fertilizer stakes work best? This tree is part of a privacy hedge so it’s very important that it continues its wonderful growth. Thanks for your help Wow now that I went to send you pictures I’m a bit alarmed! What are these brown things on the branches? They are clusters and at then extending from them is a brown twig with no needles. Yikes is my tree sick? Please let me know as soon as possible

Thank you for writing.
Fertilizing is not needed.
The disease appears to be needle cast. https://extension.umn.edu/plant-diseases/rhizosphaera-needle-cast
I urge you to have an arborist confirm the diagnosis and make suggestions for treatment. https://extension.umn.edu/planting-and-growing-guides/how-hire-tree-care-professional
