 Re: Blue spruce with brown tips
Found a PDF you can read.
Can be a bunch of things.
Look for mites ... To check for mites, hold a white sheet of paper below a branch and tap the foliage against the paper. Then rub your hand across the paper. If mites are active, you will see red streaks from the crushed bodies on the paper.
The fact that it's happening all over not just the top I doubt it's drought etc.
Could be borers, weavils, fungal. You'll need to perhaps cut a few off and have a careful look. Even use a big magnifying glass.
Then once you know what the culprit is then look for a treatment.
Be either bugs or fungal, both hard to treat. |
