Hi i have a codyline I bought at 4ft its now 6ft after 2 years in the ground, its in a south facing garden, good topsoil 18" deep then shale/clay.
I have just come back from holiday and found that quite a few of the bottom leaves have died this is normal i presume, but the worrying bit is the ne top leaves have started to die as well, they are going brown/dry/cracking and breaking, the middle section seems ok, does any one know the reason for the top dying leaves.

Regards
Andy
