Question
Hi, every year now in my flower garden I've had this weird vine wrap around all the flowers and make a mess and kill a lot of them.  It is yellow in color with no leaves and looks like spaghetti only thicker.  What is this and how do I control it?

Answer
What you have is a weed called dodder. This is an annual weed that must come from seed each year. The plant lacks chlorophyll and can not make food for itself. If you can weed it out of the bed by pulling or cutting it off at ground level before it attaches to a host plant. Once the dodder attaches to the host plant you can not control it except by pulling the host plant.  Dodder uses the host plant for it food source. Another way of controlling it is to apply a weed preventer before germination of the seed. This will kill the dodder as it begins the germination process. Amaze or Preen are two products that can be applied as a pre-emergence in the flower bed. You will apply these products once you have finished planting your last flowers wait about a week and then weed the flower bed very well and apply the product either Amaze or Preen and water them in.  You should have no weeds in the flower bed for the next 3 to 4 months. I prefer the Amaze product as it seem to work better in our soils and will work better in the high heat of last summer.
