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’??
