Kitasel2, you have to be quite meticulous. Left to their own devices, weeds will take over areas no matter what you plant. There are actions you can take, though. For example, if creeping charlie and ivy are now cropping up among your desirable plants, you can paint an herbicide on them so that you don't get any herbicide on your desirable plants. Or take a toilet paper tube, place it over the crown of the creeping charlie, and spray into the tube. The ivy tends to be tougher to control. If you find even a tiny bit of ivy root in the soil, dig it out consistently.

I once had a lot of Virginia creeper that I needed to eradicate. I had tried Roundup and other herbicides, but they didn't solve the problem. So I finally suffocated the creeper with layers of newspaper over the winter. That finally got rid of the problem.

If you find the ivy and creeping Charlies are too numerous to spot spray or dig out, you could dig up your desirable plants, park them somewhere else in the garden temporarily, then go into a digging frenzy with the ivy before finally just suffocating everything. Then next spring, you could replant your desirable plants,

For woodland, I'll only worry about the woody and vining plants. Not much we can do about herbaceous plants. If you like, you can spread some wildflower seeds to look better. Then you'll need to save seeds and spread again. They may not compete well against the wild plants.

Do as much as you can. But you can't get rid of weeds.
