Thanks for replies.... I should clarify.... I spent several hours pulling
as many of the weeds out as I could... but, many roots and small weed shoots
just pull off at ground level. I thought that soaking the ground would
reach these shoot that were left, and by systemic action, kill the weed
plant.

Next time, I will just spray round up on the full weeds, let them die off,
and then pull them out.
