I think /thought I had a health pine. it’s a Scot pine – and its on older 2nd year needles. The tip is hard brown and there is a yellow ring around the needle for a 1/8 " . Then the rest of the needle is a dark green . I’ve included a photo of it . Can anyone tell me if its a problem and what the problem is? thank you
Could be a few things, sun scald/burn, nutrient deficiencies, heat stress, overwatering. What are is your Watering? Fertilization? Temperatures?
How old is the tree?
It also could be normal needle cast, since we are headed into fall.
Check out this reference https://www.forestryimages.org/browse/detail.cfm?imgnum=1371071. looks like possibly the start of needle cast which presents in the fall. You decide.
Looks like sun damage to me.
