Cardinal Climber Blooms and Ferts

I have 2 cardinal climber pots, one I fertilized and one I did not fertilize all season. The one I didn't fertilize gave me exactly one flower, the one I fertilized gave none. They grew like crazy, but one bloom total. Same soil in both pots, pots are both 10 gallon nursery pots.

I became frustrated and reasoned they would die anyway being annuals, so I dumped a huge amount of schultz 10-54-10 in both pots. Now I see lots of buds.

My question is, what is the story with these plants and fertilizer? Or did I get a bad batch of seeds?

Thanks,

Maureen

I think your problem owns up to the fact, that too much Nitrogen, the first number on the box, causes foliage growth and what you've done is the Phosphorous, the middle no. is high..for oodles of flowers. your seeds struck, so happy gdng............Elaine
