How thinly do you actually sow alyssum?
I got some Carpet of Snow Alyssum seeds late last season and tried them out before starting a hanging basket this year.
The package says that the seeds need to be sown 6-8in apart. Is this really the best way? Last year each of the seeds grew a single stem, which resulted in nothing like a carpet. It was really quite ugly and thin looking.
From the pictures of alyssum I see elsewhere, it seems to me that they are typically sewn way, way closer. Maybe an inch apart if even that.
So what is the best way to create the carpet that pictures show? How do you sow yours?
