If a pear tree stops fruiting, it can often be revived over several years—if the trunk is sound and you commit to regular pruning and pest management.
Cut a 20+ foot tree back by 6–8 feet. Prune main branches to strong side shoots. Remove dead, crossing, or hanging limbs. Thin the upper canopy by one-third for light and air. Use a ladder and pruning saw.
Clip strong new shoots from the upper tree during the first summer after pruning.
Remove up to 2 more feet from main limbs. Shape to open the center.
Remove half the new shoots.
Spread compost to the drip line to suppress weeds and add nutrients.
Apply dormant oil and fungicide in winter to protect against pests and disease.
