Over the years I’ve written about various causes of yellow foliage on black pines. In an effort to record all of this information in one place, I’ve created a new guide that provides info on the following categories of yellow foliage:
- Old needles are turning yellow
- New needles are yellow near the base but green towards the tip
- One or more branches are yellow but the rest of the tree is healthy
- Yellowness accompanied by spots
- Yellowness accompanied by brown or black needle tips
- Shriveled or twisted yellow needles
- General Yellowing
- Yellow on the upper side of needles
Old needles turning yellow in fall
You can view the guide at “Why is my pine yellow? A black pine troubleshooting guide.“
I plan to update the guide as the need arises, so feel free to provide suggestions for improvements in the comments below.
