How to Make Delphiniums Bloom Twice in One Season

Delphinium seeds - If you love delphiniums and wish the beautiful, tall, blue flowers would last throughout the summer. They do not, of course, but with this simple tip, you can actually get these gorgeous, flowering giants to bloom a second time within the same growing season.

Here’s how it works. You have to be brave. When a delphinium has finished blooming, if left alone, the flower head is going to gradually turn to seed.

Your choice is, do you want seeds or second blooms?

Want Seeds?

If you want seeds, you just have to leave it and wait. The plant will put its energy into seed production.

Want Blooms?

If you want more blooms, it’s a bit of a race against time, before fall frosts set in.

  • As soon as the flowers pass their peak, you have to remove the entire flower stalk. By doing this, the plant will now put its energy into sending up more flower shoots instead of working on seed production.
  • To remove the flowers, follow a stalk all the way to the ground and cut it off as close to the ground as possible. Do not remove any surrounding leaves or foliage.
  • It’s a bit sad to do, as even the aging blooms can be very pretty, but, suck it up, Buttercup, as the saying goes, put the cuttings on display somewhere, and, unless something weird happens, you will probably have a second set of blooms before the frosts set in. The sooner I snip off the first set of blooms, the more success I have with round two.
