herbs can be started indoors at any time. Having said that I have no luck with rosemary
seeds. Dill gets very large so it may not do to well in your window sill and it doesn't really like to be transplanted. So you might want to wait and plant it outside. Also Dill is very aggressive so if you can still use your containers that would be my suggestion.
Basil is an annual but if you pinch off the
flowers when they start forming you can keep the plant for many years.
