My flowers are alive

Petunia problem

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.
