Those problem plants aren't much of a concern in this garden. I don't have any of them at my place. Bindweed is a problem for some. I don't see much maintenance going on here. There is wood chip mulch.
We also lack many of the pests that plague gardens. With very little use of pesticides around here, there seems to be a pretty good balance of predator and prey. I never do one thing about pests, other than creating reptile habitat. They eat slugs snails and wire worms. Airborne pests are not much of an issue.

https://permies.com/t/27910/permaculture-projects/Dale-Day-Garden This is a garden that I helped create a few years ago. It is 2 kilometers from the public garden. Although it's in full sun, we didn't have many weed problems, other than some bindweed that constantly climbed up the fence. Go to the center of page 2, to see just how dense it got.
The crops were grown so tightly together, that it didn't leave much room for unwanted plants.
I went from no garden, to producing about 10 times what I could eat, within a few months.
It's called, Dale's 3-day Garden, because I gave it three days of hard work to get the whole system going.
Some people grow weeding gardens.
Some people grow watering all the time gardens.
Some people grow, everything died gardens.

I prefer Harvest Gardens. Plant a very dense mix on quality soil and then harvest as fast as you can, so it doesn't bolt.
This little food Forest seems to be at a point now where it is a Harvest Garden. A fellow from Australia called that permaculture

.
The next time I go there, I will try to get a distance shot.
