Extracting weeds by hand can be a little bit "fun" - for a while, especially if you can get a good hold of them and feel that powerful, wonderful, ripping of the very essence of their roots and life from deep underground.
And then there's these little, round-leafed things that spread out in such a manner that a major dose of luck is required in order to grasp enough of it, close enough to its "central root top" that it doesn't break off at the surface. Getting pretty upset sitting here thinking about it.
These are the same little weed guys that seem to be almost impossible to kill with the chemicals. *And*, they've found a way to grow up *through* that black stuff that has lain under the "rock beds" for apparently too many years, now.
Guess I'd attend a seminar for learning solution options. A YouTube video might be better. Bet somebody knows the name for these particularly heinous little weeds around here.
New black stuff would seem to be an awful lot of trouble but, were it to come to that, I think I'd consider also replacing all those stupid, floating rocks with some version of "hardy" hibiscus plants.

Dirt gathers on top of the black layer over time so you’d just have the same problem with new. There is a type of roundup that not only kills weeds but prevents new for 3 months wherever it is sprayed. Has worked great for us. There is also one that will keep weeds away for a year but that one you have to be more careful with cause it will eventually hit the roots of trees and shrubs if they are close by.
We also sprinkle Preen in our beds which prevents new seeds from sprouting. Won’t kill the current perennial weeds, but works great to prevent any new seed from starting.
