Very much enjoyed!! ### 4/5 — Petunia problem *2013-08-08, version 1.1* My petunias were beautiful one day and gone the next. I suspected deer or squirrels, but when I checked the Purdue Annual Doctor, read that chipmunks also feed on petunia flowers. The app quickly identified the problem and suggested an alternative plant - daffodils. I've found the app to be very helpful and informative. ## Frequently asked questions about Purdue Annual Doctor ### What types of plants does Purdue Annual Doctor cover?
