Blue Spruce

Asked July 29, 2019, 4:59 PM EDT

We have a blue spruce that has some bare spots, but it has new growth on the other side. I'm not willing to give up on it yet. Is there some type of nutrient or fertilizer I can provide to it and when would be the best time to do it?

Hello,

Here are some fertilization references for you.

We don’t recommend fertilizing without having a soil test first-

Bare branches are likely from too much shade, poor air circulation, and fungal diseases. Here is some information on applying fungicide -
