Hello ZinniaLove,
I am a bit confused about whether this is a response to my
It can be fun to breed your own Zinnias message thread or the start of a new message thread. I have seen several examples of "dimpled" zinnia stems similar to your photo. There can be much more extreme forms of fasciation in zinnias, and I don't consider the occasional dimpled stem as a problem. I don't think fertilizer is the cause, nor is it a cure or prevention. If you have some photos of more examples of zinnia fasciation, they would be of interest.
