Problems with Dahlias
A couple of my Dahlias are rangy with few small flowers,long stems, and sparse underdeveloped foliage. Is this a symptom of too much or too little fertilizer? I have been fairly stingy with it to date but mixed fertilizer into the hole when I planted the tubers.
One plant is about a meter high and the other was planted later and is 35 cms .It is earlier days for the latter which has not bloomed yet.
Thanks for your thoughts.
