AC™ Harrow Sweet
A late-season pear developed by the Harrow Research Station in Ontario, Canada, AC™ Harrow Sweet ripens approximately three weeks after Bartlett. This variety has shown very good resistance to fire blight. The fruit size and appearance are similar to that of Bartlett; however, AC™ Harrow Sweet does develop an attractive blush. Trees should be thinned to maintain fruit size and avoid biennial bearing.

Our European pear trees are grown on OHxF97 and/or OHxF87 rootstock. 97 produces a standard size tree, is hardy and productive. The recommended spacing for plantings on this rootstock is 12’ between trees in the row and 20’ between rows. For growers who wish to plant a higher density pear orchard, we recommend planting trees on OHxF87. These can be planted at 5’ in row and 12-14’ between rows. All of our Asian pear varieties are grown on Betulaefolia rootstock. This rootstock is vigorous, well anchored and drought tolerant.
