Leave a Review Purdue Perennial Doctor
Hosta
Shows pictures tells you problems but not cures. Sent me to a page that had nothing to do with hosta plants😡Love this!
The only reason my garden is surviving is because of this and the Purdue Annual Doctor app. My Black-eyed Susan is looking much better since I identified that it had downy mildew. Most definitely worth the 99¢ !!Perennial Doctor
This app is written by two leading experts in plant pathology and entomology. So you’re getting top-notch information in a package format that is really easy to use. You get excellent photos and really good summaries and control suggestions. In many cases, disease symptoms look the same regardless of host so to not have every host/disease photo included is not that big a deal. This has been quite helpful to me several times already.Show less
