what's a matter with my pear tree? please help
i could do with some really good advice. Am totally novice and back in March bought two apple and pear trees. The conference pear tree is not thriving and looks unwell; i need to know what's causing it and how to treat, also do not want possibility of spreading to other trees.
Symptoms; new shoots are shrivelled, with some blackening to edges. existing leaves have brown/black blotches which seem to spread across leaves, leaves then become torn and/or have found several black/brown leaves on ground. Leaves are not sticky. Branches seem healthy.
