Remove lower leaves on dahlias??

Anonymous
The internet is giving me conflicting advice on this. Should I remove the lower leaves on my dahlias (they’re pretty bushy and well-established at this point) to promote air circulation / mitigate risk of powdery mildew and other problems?

Yes, you can. I assume you’ve also pinched out the tops?

Hmm, I’ve never done this. I do pinch the tops, though. I’ve never had a powdery mildew problem with dahlias. (I have with other plants.)
