My dianthas were beautiful this spring, but have gone to seed already and have no flowers left. What happened

Dianthus are not my favorite because they bloom once and then they just poop out the rest of the year. They are so pretty in full bloom though! To stimulate your plant, let the plant reseed itself, but then cut the dead heads off. This will encourage it to bloom again. It will not bloom like it does the first 'go round' but it will get a few more blossoms the rest of the year.

They are perennials and most perennials give up a show of color once in the growing season and then remain a green plant for the rest of the season, but if you dead head (cut off the dead blooms) you will likely get a second weaker bloom later in the season. I have hundreds of perennials and I constantly have flowers blooming because I plant different varieties that bloom at different times. For more color all season long add in day-lilies, phlox and balloon flowers since they all have a long bloom period. Annuals bloom longer but have to be planted each year.
Reply:You have probably had warmer weather than usual, just cut off spent blossoms, seed heads and you will probably have a new flush of blossoms.
Reply:Well if you live in Florida they "bloom themselves out' because there is no real winter.
Reply:Depending on what part of the country you are in, dianthus ARE early blooming plants and are done flowering by this time. Earlier in the season, if you cut off the bloomed out flowers right away, you might generate more blossoms, but otherwise, I'd just suggest balancing your garden with something that blooms later, like phlox.
Reply:If they are the perennial type that are low growing, blue foliage that stays blue/green all year round, such as Bath's pink or Firewitch, all you need to do is trim off the old bloom stalks with scissors. You can get them to bloom every three weeks with adequate water.

Trim the stalks back down to the spikey foliage.

If they are Sweet Williams, also a perennial dianthus, same thing, except only snip the old bloom heads.

Other than that, they would have to be the annual type, in which case, they should still be flowering on their own.

Hope this helps
