Roundup Tree Stump Weedkiller, Super Concentrate 250 ml

Takes a while to show effect that tough weeds are dying, but of course it takes time for it to reach the roots.

Bought and used this last year in September. Used for two conifer stumps about 6" in diameter and three shrub stumps about 1-2" in diameter. Drilled holes as recommended and applied twice. This week, which is about nine months after applying the killer, I've finally got around to trying to get the stumps out. An important point to make is that it's a stump killer and not a stump rotter i.e. it stops further growth on the stump but doesn't rot the stump making it easy to get out of the ground. It does the same for the roots which are still as difficult to get out as before applying the killer. The shrub roots turned quite a bright yellow (which surprised me but is evidently common) and the conifer roots were a browny colour. When I bought it I was expecting it to rot the stumps but perhaps that was wishful thinking but it did kill the stumps so that was a good. Maybe if you leave it for a few years it may rot the stumps but I have no way of knowing. Overall I'm pleased that it prevents further growth from the stump but a tad disappointed that it didn't rot the stump.

Good item just used to kill 3 stumps now rotting I hope only used last week

I've been using Roundup for years and it always works very well, not just on stumps but also tough weeds on driveways and paths. First, a word or two of caution: 1. Don't use it on a windy day. Works best when the sun is shining when the air is dry. 2. Always wear a face mask and some protective gloves and footwear 3. Keep away from children, pets and fish tanks/ponds 4. To kill weeds where there are other plants nearby. Cover the other plants as much as you can and if need be paint the weed killer on the foliage of the weeds. 5. If you have chopped a bush or small tree/shrub. Paint the weedkiller on and then cover with a clear plastic bag held on by tape or an elastic band in case it rains. It will take longer to wipe out a stump but it will kill the deeply buried roots. 6. The concentrate form is best in terms of value for money 7. Try to avoid leaving it in a sprayer for a long period of time. It tends to clog up the misting nozzle. Good Luck - and if you can't get any round up use a high pressure steam jet or a kettle of hot water. :)

Used as directed 10 days later it has done nothing. Going to double or even triple the dose and see if that helps.

My mother swears by this for bind weed and blackberries.

Seems to have done the job on a bit of knotweed Will need to check back in a month

This will kill off your brambles etc, but like most stuff needs several applications. It's not once & done
