I use a lot of Sweet William plants, growing from seed for myself and 2
daughters. They are finally grown in tubs, this year I was late in
removing them and have not yet planted up the tubs. In the tubs are
scores of, what looks to me like S W plants. Can I successfully grow
these on to become healthy plants to plant out next Autumn? This is when
I plant out those I have grown from seed sown in the Spring?
