Pyrus communis 'Harrow Sweet'
Harrow Sweet is a late-season pear characterized by small-to-medium sized fruits which usually have a pretty orange flush where the sun catches them. It is related to Bartlett, and the flavor is very similar - although it ripens later.
It is a good alternative to Bartlett in areas where fireblight is prevalent, since it is very resistant.

Harrow Sweet has a tendency to over-crop, which leads to small fruits with poor flavor and can also induce biennial bearing. This can easily be prevented by heavy-thinning of the fruitlets in late spring - aim to remove 4 in every 5 fruitlets if there has been a heavy set from the blossom.
Harrow Sweet is also precocious - it will start cropping from an early age, and this should generally be discouraged by removing all fruitlets for the first few years, to ensure the tree grows to its full size.
Harrow Sweet is not self-fertile so will need to be pollinated by another compatible pear variety. Despite the close relation to Bartlett it can be successfully pollinated by Bartlett, as well as most other varieties that flower in the middle of the blossom season.
Advice on fruit tree pollination.
Harrow Sweet (also known as AC Harrow Sweet ) was developed in the 1960s at the Agriculture and Agri-Food Canada research station in Harrow, Ontario. The same breeding program also led to a sister variety Harrow Delight, and Harrow Sweet shares the same Bartlett-dominated parentage.
