This is about the fourth plant this season that I've had the same trouble with. They are just fine and really pretty most of the season and then they start getting brown at the base and the plant continues to die off from the base up. I've had this with marigolds, straw flowers, one perennial I hadn't identified and so on.

Is it a fungus? I don't see any bugs so I don't think that's a problem. I sure am tired of losing all my flowers!! I'm hoping someone has an idea....

Here a pic of the lavender. -- Vicky
