Welcome to the weekly gall thread! All questions about gall should go in this designated thread rather than new, individual posts. A new thread will be started automatically on a weekly basis. This will ensure the list of new top-level comments remains short and easily reviewable by folks who are kind enough to let you know if they see signs/symptoms, or if your plant seems ok.
Because Reddit only allows one photo embedded per comment, here are some tips if you need/want to share more than one photo for the best chance at a solid review/answer from the community:
- Start a top-level comment with your best photo, and reply to your own comment with any additional photos you want to share.
- Post photos to an album such as imgur and link to the album

This is an automatic reminder regarding r/dahlias Rule 3:
When reasonable*, posters should make a good-faith effort to identify which variety/varieties are shown in their photo(s). If you don’t know for certain, please say so. Someone will usually know!
*Common-sense exceptions to this rule will be honored, such as if the photo does not contain a blossom, or if your photo contains large volumes (such as in wide field shots).
If you’ve already done this, thank you! No further action required.
If not, please add a reply to this comment and confirm if you know the name of your dahlia variety/varieties shown in the photo(s). Alternately, if you’re uncertain of the variety name(s), it’s ok to say that, too.
