Hello everyone,

Starting about 7 years ago we had this strange giant 10 foot weed show up in our yard. We pulled it up and thought we were done. Now every single year it comes back more invasive than the last year. Now, it has managed to take over our entire back yard. We have tried spraying it with a vinegar/water/dawn solution but it did absolutely nothing. We have to be careful with what we use as we have 4 dogs.

Can anyone please help me identify this huge plant and tell me what we can do to get rid of it.

I tried to upload pictures but it would not let me do it.

I do now know what it is. Due to understanding chem. problem with dogs maybe I can help. Maybe if situation fits you can put cardboard boxes down in that area after you have cleared it. Make sure you even double it and also overlap boxes. Then put wood chips or something like that over the cardboard boxes. You might have to do this yearly until all the stringers are dead. If you have other plants in this area just surround it with cardboard boxes also and mulch also. The boxes will allow water to go through but not light. Maybe this will help this giant weed from coming up. Wont hurt to try it if this is o-k to do with your dogs. Maybe this will be helpful.

Sounds familiar. Google Japanese knotweed. It's very destructive to retaining walls and foundations. It grows from the root system. I have talked with the local conservation district people. They say if you cut what's above ground, the roots grow more rapidly. They have an injector they loan out and suggest injecting the stalk with Roundup late summer or early fall. We have chickens so I have not taken that route. I have excavated about 50 yards and its still growing. Good luck.

Pour some gasoline on it, your dogs won't mess with it and the plant will be kicking up daisies.
