Experts and BHG readers answer.
the leaves on my cleavland pear tree are turning brown on the ends what's wrong?
Brown leaves on a pear tree could be an indication of one of several things. If the entire branch tip is turning brown, it's likely fireblight, a bacterial disease to which pears are susceptible. To prevent the spread of this disease, cut out the browned shoots well below the point where blackening is visible, and be sure to sterilize your pruning tools in rubbing alcohol or a 10% bleach solution between each cut.
Other possibilities for browning leaves could be freeze damage or scorch from dry, windy conditions.
