interior /yellowing/browning is NORMAL ...

no pine holds its needles for more than 3 years ..

and the oldest.. interior ones... fall off.. every.. single.. year ...

never feed them again.. its a pine tree.. not a child and a complete waste of money ..

no need to even water them again ... adjust the sprinkler to avoid such .. it should never hit a conifer ...

it feeder roots are at least as far away as the tree is tall.. so it will get whatever water it needs from the lawn ... and that would include lawn fert ....

it will do best if you learn to ignore it .... other than to simply look at it.. and enjoy it ...

there is a conifer forum.. should you wish to be enabled

Thanks so much - so big picture: This is normal and quit listening to our expert friends! :)

[And kill the sprinkler near it]

Thanks for the quick advice and tips!

Drive around your area and observe. Pines, as a group, tend to drop a percentage of their needles in the fall. They can look pretty darned ratty for awhile. Other conifers have differing habits.

most ... want a drink of water.. then NEAR drying... deep in frequent waterings ...

and many.. will become diseased.. if kept wet above ground ...

they are all basically forest trees.. no one waters.. and no one keeps the foliage wet ...

when you dont know a specific.. default to the obvious.. see link for the obvious .. lol

Here is a link that might be useful: jsut about darn near idiot proof.. they need nothing in the whole world.. ever .... except to be watered.. IF YOU MOVE THEM ...

Where do you live (roughly) that you need to 'soak' your lawn every other day?
Pines, as a general rule, require FAR less water than a lawn and almost never need supplemental fertilizer.
