Dahlia losing it's flame

I bought a red flame Dahlia this year for the first time and it's done very well still has lots and lots of flowers on it BUT I have just been digging my greenhouse base and found it to be losing colour from a bright red to a glowing orange is this normal for dahlia’s to lose its vibrancy at the end of the season or I’m I doing some think wrong??

I have also bought a new pink Dahlia for next year but its struggling to much and I don’t think it will make it through the winter be we will see the foliage is really damaged by slugs (bought as a rescue plant ) a week or two ago and still in its garden centre pot ( just waiting for the frost to come so I can life and store it

 

Another question, should I still be feeding my Dahlias’??

    Some of my dahlias do change colour as they get older so yours might be fine. 

    I'm not sure about feeding - other people on this site will know more than me - but I would think it would be OK to keep feeding it.  As I understand it the tubers are still growing and feeding at this time of year, which is why you don't cut back the top growth until after the frosts have blackened it (to maximise growing time);  so I'd have thought they'd still appreciated food if you want to feed them.

    I'll be interested to see what other people say - I don't usually feed my dahlias because my clay soil seems rich enough for them, but maybe I should!
