browning of small pine tree
I have a pine tree in a pot I put it in my south facing balcony
It has been neglected little
I water it once every week or sometimes every 4 days
I just water it I am not even look at it's needles in the other side of it ( I mean the part that not facing me when I water it )
Today I turned it and I see brown needles at the upper side of it and this browning is from only the side that facing sun I hope that I make you understand me .
The brown needles is very brittle all the tiny brown hairs of needles fall off when I touch it. I water it now after I see this problem . do you think this is under-watering sign?I didn't water it for a week
The weather here now is about 23 c at night to
should I prune these needles? and how to water it correctly ?
should I re-pot it ?and move it to more sunny place?
please give me your advice I love this tree so much
