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.
