Just a quick note about soil seed banks. If you are not familiar with the term, it is where seeds are stored in the soil until conditions are appropriate for germination or where they decompose. There are thousands of seeds in a seed bank and not all will germinate at any given time or any given set of conditions. That's one of the reasons annual weeds are a problem year after year, even if you kill the current year's weeds before they produce seeds.
If you need proof, I'm attaching a photo of a plot that was tall fescue turf for the past 5 years and there were few weeds in the plots. I then shut off off the water for a few months and the fescue died. I recently started irrigating a few plots and up came a bumper crop of...

Don't confuse WPW with other waterprimroses, similar weeds that are usually seen around rice fields and ditches and are prostrate. WPW habit is erect, the yellow flowers have 4 petals, and the stem has wings or membranes that run longitudinally. Unlike other waterprimroses, WPW can grow within...
