The tallest blooms of some of my larkspur are starting to go to seed, with a few flowers on top of the largest stem.
I am in mind to cut them off. Would this prolong the flowering ? The plants are quite bushy and the shorter stems are still in bloom.
They are flowering beautifully and it's the first time I've grown them from seed so looking for a way to prolong the flowers if possible.
Thanks for any advice
