Warren European Pear

The biggest problem with growing European pears in the Seattle area is pear rust (fungal, orange spots on leaves and flower drop, fruit drop, ultimately tree dies). Are there any European pears which are not susceptible to fungal pear rust; or, what systems for control of fungal pear rust are effective? Thank you.

You are correct. Gymnosporangium infections (which strike apples, pears, quince, and hawthorn among others) are prevelant in many cities due to the abundance of cedar and juniper used in landscapes. Unfortunatley resistant fruit trees are few and far between, but the good news is that fungicidal sprays like Bonide (copper sulfate) are considered organic, and are effective when used annually. Apply when new growth begins in spring and repeat twice more at two-week intervals. This should provide adequate protection for your tree during the sporification period and prevent disease.

Does this pear need to be planted with another like pear or with a different type of pear?

Another cultivar of European pear is necessary for cross pollination.
