What are some disease resistant apple cultivars to grow in Iowa?


Disease issues are a primary limiting factor to producing high-quality apples in the home garden.  Without regular fungicide applications, most apple cultivars will develop serious issues with diseases like apple scab, fire blight, cedar apple rust, and powdery mildew among other diseases that will limit the size and edibility of the apple crop.

One of the best ways to grow high-quality apples at home with fewer inputs in fungicides is to plant cultivars that are naturally resistant to common apple diseases.  Select one of these cultivars for your Iowa home garden to get good apples with fewer inputs.
