Dry curling leaves on bay tree which has done well for last two years now seems to be dying off. Not like ones I've seen in garden centres one main trunk mine has five stems from root 4 curled drying leaves, the 5th still fresh and green but may go say way. Can't see any indication of bug attack. In 18" pot and reasoably sheltered positon....could it be pot bound or would it be lack of neutrients? At a guesse it is about 4yrs old.
Thanks in anticipation.
