Great!
Those yellow flowers look like new growth - don't cut them off.
Just cut off the spent blooms .
Keep the soil damp not waterlogged .
It look promising !

Oh dear !
Don't despair !
Give it a trim and a rest .
And see how it goes...
At the end of the summer : store upside down to empty the stalks of all moisture and wrap it in newspaper in a cardboard box .
In April , plant in some compost mixed with top soil indoors and watch the leaves grow from the tuber .

You could chop it down, leave a bit of stalk and a couple of leaves at the bottom, move it into the shade and keep watering it. It’s worth a try, if it’s a tuberous dahlia it may not be totally dead.
Thank you will try that….

Oh dear that looks like one deceased dahlia! Cooked perhaps?
Yes I don’t think there’s any coming back from this situation unfortunately…?

I hate to write it but, repotting your Dahlia when in full bloom in a heat wave would shock it !
Just continue to water and make sure that it isn't sitting in water .
I'd be inclined to give it Tomatorite feed ,but follow the instructions don't overdose .
When I repot - I like to dip the roots in a seaweed drink ,which is well diluted .
Always cut off spent flower heads .
I've had plants do this because they've fried in the car on the way home from the nursery .
Don't worry .
I'm sure that it will pick up again !
Again thank you very much….
Oh no, your poor dahlia looks very poorly.
I think it might have a virus called verticillium. It was probably in the soil when the plant came from the garden centre. You said you might have overwatered it and this virus thrives in waterlogged soil. The virus stops the roots of the plant from taking on water - it literally dies of thirst even when it has plenty of water. If it's this there's nothing you can do to help this plant. Just make sure that you don't put the soil into other pots or the garden as it will pass on to other plants.
I would take the plant back to the garden centre and ask for a replacement/refund.
You said you're a novice and I do hope this won't put you off gardening Shinamae. Dahlias can be tricky buggers, but most plants will thrive especially as you are so keen to look after them well.

I notice that your pot is placed in a saucer that looks like it has water sitting in it. You might be drowning your new buy.
Plants like a good soak and then to drain and dry out a bit. I would give the plant a good soaking and then remove the saucer and let it drain for a days or two before watering again. Stick your thumb in the compost and only water when it feels dry.
Another thought - you said it was too big for its original pot. Were the roots packed in very tightly? If so, did you loosen or tease out the roots a bit before you potted it on? It might be in such a tight tangle that the roots can't get a good drink from their new compost. Lots of videos online of how to tease out roots.
Hope that helps and that your dahlia perks up.
