I live in Pickerington, Ohio and would like to know what pests and diseases are common to the area and affect fruit trees and shrubs. I plan to plant as many different fruiting plants as possible, but I'll restrict this email to apple trees. Concerning apple trees: 1. What pests and diseases do I need to be concerned with (so I know which disease resistant varieties to get, if any)? 2. Would columnar apple trees make sufficient pollinators of a large (i.e., semi-dwarf) apple tree? 3. What red-fleshed apple varieties would grow best in my area? I'm also curious about their respective bloom times, which is hard to find data. Thank you! Tim

Hi Tim,

We have quite a few factsheets that answer your questions. There is on one apple specifically: http://ohioline.osu.edu/findafactsheet

Answers:

1. Apple scab, powdery mildew, codling moth, Japanese beetle and others.

2. Columnar apple may not produce enough flowers/pollens for pollinating other apple trees. Sargent crabapple is a good pollen source. You can also graft different apply cultivars on your existing apply tree.

3. I do not know which red fleshed apple variety will do better than others. I think they all very similar to common apple varieties in terms of pest and disease issues.

Hope this helps. Happy gardening!
