<pre>Alan and Judith describe very accurately the symptoms of what I suspect has
killed one of my Sevillano trees and near killed another. These two trees
are isolated in a batch of 60 other Sevillanos in a block of about 500
olives of other varities. All the trees have been given similar treatment
planting , irrigation ,fertilizing-sheep manure] and appeared otherwise
healthy until the development of lumpy bark with the addition of short
vertical slits or cracks appearing over the whole trunk and partway along
the major branches.
I do not suspect sunburn as has been suggested but tend to think it is
nutritional, either deprived or excessive.
Any suggestions or similar experiences may help both myself and the
Leslie's.
