    Hi, I have a nasty feeling I shouldn't have been feeding my container grown cornflowers (with trailing geraniums etc) as I haven't had any flowers- just lush foliage.
    What a disappointment !
    Am I correct?
    Thanks in anticipation

      Hi Gilly,

      Thanks for your comment. Yes, you're right. The cornflowers won't need the plant food and will just produce foliage rather than flowers. The geraniums will have appreciated it though!
