What to do with them now they are fading? Do I deadhead? Can I get seeds from them? Help, I loved how they turned out and would like more. I know they are biennials, so now what?
If you don't mind changes in color, let them re-seed. They don't breed true, but I always like to be surprised. If you insist on a certain color, yu need to deadhead and replant. If you choose to re-seed, trim the brown flower heads off once the heads are empty. I usually cut some of the flower heads off and lay them wherever I want a new batch to grow.
Packet of Sweet William seeds showed one stem with cluster of flowers and biennial. Mine came up single flower and bloomed the same year I planted. What happened?
In warmer areas with longer summers, it is not unusual to see Sweet Williams bloom within their first season. However, blooms will not be as prominent or clustered until they have reached maturity.
Brought a small Sweet William in from the garden as it was to turn very cold. Planted it in a small goldfish bowl with gravel in the bottom, and sat it on the sunny kitchen windowsill. Lo and behold, now have 8 fringed blooms in pink/white. Even put a worm in the bowl and can watch it. May try with one of the yellow pansies. . . fun to do!!
Sweet William, as with most Dianthus plants, are ideal for containers, so with the proper growing conditions, they should do fine indoors. Glad you are having luck with yours!
I had a beautiful bed of sweet Williams. They have now all turned brown. Will they come back this year or are they done for the season?
Deadheading the flowers will help extend the bloom time of your Sweet Williams.
If you do not deadhead the plant will go to seed and will readily reseed itself in the garden.
If all the blossoms have faded you can cut the entire plant to about half of their height. It is possible for the plants to rebloom in a season.
