Do you intend to plant your dahlias outside now? I wouldn't do that just yet. Better to pot on again than plant out right now.
Pinching out is good idea. It will make for sturdier more floriferous plants
Im in Cornwall and some of my dahlias have just been put outside but that's cos the night temps here are 7 to 10 right now
