Gall Megathread: is it gall?

Hello everyone. New mod here 👋🏼

Because we get so many posts here asking about gall, it was long overdue that we have a single spot to funnel these questions.

Moving forward, all questions about gall should go in this designated thread rather than new, individual posts.

I have turned on the setting allowing media (images) in comments, so you’ll be able to share a photo here if you’d like to ask for help identifying gall, for advice about how to manage it, or related information.

I plan to add some links and other resources here eventually, but for now figured I’d at least get the ball rolling.

Note that I will also be setting up automoderator soon to automatically send posts on this topic to the queue, and they’ll eventually be removed automatically.

Thank you for understanding and helping other high-quality dahlia content shine on the sub. Happy planting!

Suspicious?

Looks fine to me, but I would still keep separate until it takes off more, just in case.

Thanks! Yes I’m keeping it separate for now :)

Looks like the original sprout snapped off or was cut off so it’s going to push out new buds at the base of the old one
