It helps to spray pokeweed early. Trimec plus organic wetting agent.
This one was sprayed down low where the stem was in a rapid growth stage.
Of course, you may have to hold a shield to protect the flowers from the spray mist.
Cardboard on a stick, or child-size plastic snow shovel?
Maybe someone makes a directional nozzle for a backpack sprayer.
Pokeweed has plenty of deep roots, with which to return next year--or so I have heard. Dig out the roots if the pokeweed gets tall every year. Around here about 6 feet is the maximum. Our winters are cold. Does anyone have good pictures?
I would think cutting them off early in the season would prevent them from sending food to the roots. Heavy duty string trimmer? Repeat if needed?

Thanks Riggle. My pokeweed is growling in one of my pollinator gardens. so digging is not an option. I will be cutting them. Spraying with a non-selective herbicide would be difficult due to close proximity of desirable plants.
My plan of attack is to cut them down and apply nonselective herbicide to the stump. I'll probably have to repeat application in the spring.
Any other suggestions are welcome. :)
 
How about a dandelion weeder?
Or shovel and pop a clump take out pokeweed carrot and replant good plants?
How many and how big?

A new plant from seed should only have a root like a giant dandelion

It's when it's been cut off repeatedly that it grows a big deep taproot

These are 6ft tall and there are about a dozen of them.

You can treat them like a giant dandelion and try to get as much root with a shovel or even a hori knife

As each new stem or leaf comes out repeat war of attrition 👍

Dig out any remaining roots in the off season after the garden is done

This is my plan of attack: Treating individual plants with the systemic herbicides glyphosate or triclopyr can be effective. Glyphosate is a nonselective herbicide that will kill both broadleaf plants and grasses. Triclopyr is a selective broadleaf herbicide and will not injure most grasses. These herbicides can be applied to the foliage or to the cut stump after manually removing the stalk. In addition, I will be collecting the berries to make sure seeds don't germinate.
 
I was going to mention don't let it go to seed
The seeds can be viable for decades I think 40 years I read
They sprout when land gets cleared or brought to the surface

New construction lots often one of the first weeds to poke out....

It's not hard to manually get rid of either just takes a few attempts and watching for the resprouts

Either way I am sure you will be successful

Yeah, I let it get out of hand. But like I said earlier, it's all out war now!
