[Arid_gardener] brown needles on Aleppo pine

[Linda Drew]

It depends what is causing the brown needles.
Old needles naturally turn brown and fall off as
new needles emerge.

In some cases spider mites (tiny sucking insects might
cause browning. Spray the foliage with a strong stream
of water in the early mornings for a week or so to get
rid of them:

Pine blight also causes brown needles. It isn't really a
disease and responds to good care:
