Hello everyone,

I recently got this Sylvestris, after cleaning the tree i noted some needle yellowing with sap coming out. Didn’t notice this before and as you can see the tree pushes out a lot of pine cones and has good back budding so i assume the tree is very healthy.

Should I be worried? Please help me diagnose the issue.

Looks pretty healthy to me. Maybe had a day of bad watering or heat? But I wouldn’t worry about it just focus on consistent watering.

I would give it copper spray. If it’s watering issue all needles tend to yellow evenly. Yours have rings and only on some last year’s needles. To save this year’s growth protect new needles.
