How well does this work on Canadian Thistle? These have a deep tap root that has to be removed.

I dont know about canadian thistle specifically but i can say that I've used it to pull some surprisingly deep dandilions

I used just drop of Tordon on a freshly cut two-year old dogwood seedling where the roots were totally entangled with an established Azalea. there was no way in this case to remove the tree stem/roots from the azalea. The dogwood never came back, and the azalea died within a month. I love this product for invasives, but be careful.

I wouldn't buy this one for thistle...it will just fall out all over the place when the birds land on it....it is perfect for black oil sunflower though.

I've been using it for about 1 year. I usually spray around the plants close to the roots but when I spray the hostas and yucas I do get a fair amount on the plant. Haven't seen that it hurts them in anyway.

I sprayed with a pump sprayer and did the best I could do, especially the lower affected leaves. It did work. My cousin told me about it. Then the darn frost got them before they ripened.

I agree with the others. The openings are too small and you'd loose too much of the thistle seed.

Yes I recommend this. I got big buds from using this. Just don't try to overdo it or you'll burn the roots.

I have not experienced this particular weed. However, Id bet it will do the job. I use trimec because it kills all the weeds Ive encountered. If you have ever experience creeping charley youll know what I mean.

I used them with good results on my indoor basil. Don't see why it would not work on other herbs as well. Happy gardening!

I think these would wear out fairly quick on rose cane. Work great on other plants though.

Yes it works well. I am using it all winter long when the infected plants are sitting under growth lights.

I've only used nijer (thistle) seeds so I cannot give you an objective answer regarding the use of other types of seeds with the feeder. The birds appear not to have any problems extracting the thistle from the slots in the tube. Sorry I could not be more helpful in answering your question with regards to other seed types.

no, the openings where the birds get the seed are much to large for thistle. sorry :)

I'm not positive, but if the unwanted stalks share a root system with any of the wanted stalks, I would NOT use this product. I am able to kill all invasive ivy by spraying only the leaves, and it works down to the roots. I would say NO, to your question.

Thank you for replying. I have a flowerbed filled in with river rock that I have been having difficulty removing pine needles from. I don't want to get every last one but it looks shabby the way it it.

These are great for most herb plants. Keep an eye on the roots on the bottom to make sure they're not too cramped.

Depends on how hard. To get all the roots out, wet the area and wait a while. You have to press hard otherwise, possibly damaging the device. If you can readily penetrate the soil with foot action, it will work well.
