There is a relatively new broadcast spreader called "Edgeguard". It is
supposed to allow us to use it near the edge of a lawn without worrying
about spreading herbicide into the flower bed. This new broatcast
spreader has a shield or something that prevents herbicide/fertilizer
from spreading into the direction of the shielded area.

My questions a

- Does the shield really work?

- Does the shield cause a lot of herbicide dumped right under the
broadcast spreader?

- Any other downside (other than the high price)?

Thanks for any info.
