Chickweed around my raised beds
HI! I have six 4 by 4 ft raised beds surrounded by walkways of pea gravel (dumb idea I see now, but such is life...) I have been fighting a loosing battle with chickweed and another smaller leafed weed. The roots are so sticky to the gravel and fine that I can't get it all out. I have gotten a lot out, but there is still fine layer of green over a large portion of walkways. I have used a 4 prong tool that twists the roots to loosen things up. I am thinking of putting landscape cloth over it to try to smother it, but I think I should put some herbicide or something down before I cover it. The top of the soil level in the beds is at least a foot above the gravel level. What is the best way to kill the weeks, while still allowing my veggies to grow? thank you!!!
There are several types of chickweed, some annual, some perennial, and their seeds can stay viable in the soil for many years.

It sounds as if with the "fine layer of green", that you may have a whole crop of weeds getting going.
Your idea of smothering is great. Anything that blocks light will work.
