Q.“Pinks” Dianthus problem
I am a novice at gardening, so this Spring I was determined to plant some flowers/herbs for the first time. That being said, I have a “Pinks” Dianthus plant in an appropriate size pot on my front step. We get full sun there. We have noticed that the flowers are coming off. There are many buds and the plant/stems themselves look healthy. I have read that spider mites could be to blame? Is it possible that squirrels could be eating the flowers off of the stem? Thank you!!
Yes, squirrels, mice or rabbits could be an issue.
It's doubtful that spider mites would cause flowers to drop.
