do dianthus flowers rebloom time and time again?or do i have to cut old blooms off and then they bloom again?

Answer 1

I agree with yahzmin. In my experience the Sweet William type of Dianthus bloom better when deadheaded. You do have to get right down there to see. Sometimes there are still buds on the stems with spent flowers. As long as you are not talking about Carnations(also a Dianthus). I think when they're done, they're done :-)

Good luck :-)

Answer 2

Dianthus Bloom Time

Answer 3

There are a number of kinds of dianthus, but generally speaking they seem, like most re-blooming flowers, to do better with deadheading. Flower plants really just want to reproduce themselves (set seed), and when they succeed in doing so, they figure that their work is done and they have no more need to produce flowers. When you deadhead, you give the plant the message that more flowers, and thus more seed, will be needed if the plant is going to perpetuate itself. I personally sort of hedge my bets by pruning really carefully, taking off the seed heads but only cutting back some of the stems as far as a joint where you can see new flower buds coming on, so I get some new flowers on a consistent basis (but never as spectacular as the first bloom.) Any time you deadhead, especially if you cut back pretty severely, give the plant some fertilizer and water it in. If you do organic, add some good compost and give the plant a shot of diluted fish emulsion; the compost will help keep the soil moist and give a longer lasting source of plant food, and the fish fertilizer gives it a quick boost. (Warning: even the deodorized fish emulsion smells a bit fishy, and I have had cats come to investigate!)

Answer 5

They have a very long blooming season but do not cut or "dead head" them or it will not bloom again for a long time. I know they can look tacky, but they will perk back up in no time. In Houston, mine bloomed year round:)

Answer 6

My mom grows the "Sweet William" and just lets it self-seed, but, from The Garden Path:

"This too is another plant that needs deadheading to really give you it's full bloom. " (see link for further info).

The second link varies on its pointers -- some do, some don't -- search the page for "deadhead" and you'll see which varieties it thinks do and don't.

So -- maybe you need to run your own experiment? :-) LOL! Good luck!
