Roundup by itself won’t kill large trees but if you mix two other chemicals then it will. Here is the recipe I found from the Utah Ag Extension: Although it is not a legal requirement to wear protective clothing when handling and using amateur/home pesticides, the RHS recommends wearing gloves, Wellington boots and other protective clothing as a sensible precaution. Links Each of these ingredients needs to be used in their concentrated forms. Add and mix them into a small container like a glass jar. One of the things you can do is to dig the stump up. Another option is to get a stump grinding professional out to grind it down.

After cutting down a tree, some people decide they will wait it out until the tree stump decomposes. However, this is not a good idea, particularly if you have plans for the area of land the tree stump is rooted in. The chemical composition is very important because it affects the rate of reaction. The common chemicals that you will find in these stump killers are Triclopyr which doesn’t kill grass and Glyphosate that will kill everything. Triclopyr is an organic substance that kills off woody plants and it is friendlier to the environment too. Stump and root killers currently on the market are those containing glyphosate (e.g. Roundup Stump Killer,Doff Tree Stump & Tough Weedkiller and Westland Resolva ProTree Stump killer) or triclopyr (Vitax SBK Brushwood Killer). For best results using Roundup to kill stumps, drill several 1–2 inch (2.5–5 cm) deep holes in the stump and fill them with Roundup. One thing most people don’t realize is that a tree is as big below ground, as it is above ground. When you cut a tree down to a stump it doesn’t always mean it’s dead.

Finally, cover the whole top of the stump with a plastic sheet to keep off the rain and secure in place This is a no-brainer but really what is your time worth? How many Saturdays do you want to give up to cut and remove your own trees? After reading the methods I have listed above it may be worth hiring a professional to come to kill and remove your tree. After killing and removing several trees myself it always amazes me at how long it takes when you don’t have all the right equipment.

It is worth specifying how deep you would like the stump ground to. Shallow grinding, 20-25cm (8-10in), is normally sufficient for laying turf, but you should allow for deeper, 30cm (1ft), or more if replanting or landscaping. Also think about what you want to do with the sawdust. It can be left to fill in the hole, used as mulch in other areas of the garden, or taken away by the contractors. Specify which of these you would prefer before the work is started and be sure to have any diseased wood removed completely. Mature trees are largely unaffected by moderate applications of Roundup around their drip line and canopy. Roundup is designed for absorption through leaves and tends to bond to soil particles rather than flow between them. In other words, Roundup is unlikely to be transported or flushed down through the topsoil to underground roots.

Chemical control solutions are always best applied during the more active seasons of late spring to summer as plants are generally more vigorous and forgiving during these periods. So, it is definitely the cheapest, but definitely not the strongest stump killer on the market, which leaves us asking – is it really worth it? The label on the Rootblast Super Concentrated Weedkiller may give you the impression that it will work like magic but it will take around 2-4 weeks before you see results. It is just how glyphosate works and it is what the professionals use commercially.
