You're referring to Cornflowers, right?
What I do is pinch every second plant, so they'll bush out. On the ones I don't pinch I cut the main flower stem, strip side stems, the plants will branch. But the first flower should be taller than the lower laterals. If you try cutting those secondary laterals off the main stem, you'll end some with skimpy flowers on real skinny stems. Hopefully by the time you've cut all the main stems on the plants you didn't pinch, the other plants are producing multiple good useable stems. When you're done with them, the original plants you cut the main stem from should have branched and provide more stems.
Also not being able to see the current growth/condition of your plants, doesn't help one to answer. Experiment and see what happens.

Kim, thank you very much for your speedy answer. Yep, I'm talking about cornflowers, centaurea cyanus. As you can see below, I won't be able to use your advice on my first planting, but I have two more in the ground and I'll give your method a try on those.

You are very kind to share your knowledge.

Appreciatively,

Good question Thinman and thank you, Kim. I have one quick question, At what height do you pinch the main stem of your cornflowers?

When the plant starts to form it's first main flower stem. Cut if off but not to the ground.
