I plan on using this to kill 8-10ft sumac saplings. Should i cut the sumac down first and just do stumps or the solution to the entire tree.

Definitely cut the saplings down first, cutting on an angle if you can to expose as much live wood as possible. Then, as soon as possible, brush FULL STRENGTH concentrate on the cut and for an inch or two below on the sides. Be extra careful to wear your safety glasses and gloves when dealing with the concentrate, even when just pouring it into a jar for brushing. Wrap and discard the brush afterwards where children or animals can't get to it. After a week or two, check on the stumps and spray or brush any growth. I've found this controls southern California sumac and ceanothus well.

I did some research online to see how to best kill Chinese Tallow trees and found that I could either cut down the tree and then treat the stump (which I did for smaller trees that I could cut down with a hand saw); or, for larger trees that were too much work to cut down, I found out that I could treat the base of the tree by coating about a 2-foot wide swath of bark (encircling the tree) near the base of the tree. I don't know if that's the same for sumac but maybe you could find out online or from your county ag agent. (I don't know what kind of sumac you have but I love my sumacs - they make fantastic fall color.)

If using Triclopyr, spray on full leaf and entire tree. You could also use Tordon RTU. If you use Tordon RTU, you cut tree down and pour small amount on entire Cambrian ring. Kills trees GREAT, but just one at a time.

I would cut them down with stumps as short as possible, then drill a hole in the center of the stumps and pour some of the solution, soaking the stumps. It seems neater and quicker that way without having to spray it into the air. The stumps will die and rot. Then you can break them up once rotten.

No just spray it, with in the week it will be dead including the roots. Be careful of drift, it will kill other plants. Sooner or later you will have to cut the plant, but it is easier to cut them after the leaves fall.

By far the hardest trees I have had to kill are Brazilian Pepper trees. If you cut the tree stump about one foot from ground level (I like to leave the stumps tall enough so that I don't turn my ankle on them) and then pain the stump with UNDILUTED Glyphosel Pro, it will probably kill to the root the first time. On occasion, with trees that had diameters of one foot or more, the tree will try to sprout from the stump. In this case I simply spray the new green foliage and that does the trick. It also works on Mexican Petunias which are very hard to kill.

Yes, I've read that it works, but ONLY on a LIVING, FRESHLY CUT stump. I remember reading someone else's post that, if you want to kill the stump, you need to apply this weed killer to the stump immediately after cutting the plant/bush/tree. If you wait too long, the plant forms a 'scab' (I don't remember the correct term) and then the weed killer will NO LONGER work. Depending on the size of the stump, you could apply the weed killer with a cotton swab, a foam brush or a bristle brush. You just have to apply it promptly! If the stump is still alive - and it hasn't 'scabbed over', yet - then the stump should suck the weed killer down to the roots, killing the stump.

I'm not sure but I would look at this information first...http://www.ehow.com/how_8349005_kill-bois-darc-tree.htmlHope this helpsJean

Oh no. Not unless your tree trunks are 128" in circumference. That is how many ounces you will have in your gallon container. Wait for a day when it has completely finished raining, at least an inch of rain, so the ground is damp and your tree roots are primed to soak this expensive stuff into its system. I like to wait until the little tree leaves just start to grow fast in early/mid May in my area. October works but you will have to research the timing of this on line. Get out a measuring tape and measure the circumference of your tree trunk 40" up from the ground. Check the label directions to see which formula you have. Regular formula Bayer will state to use 1 oz of liquid per inch of circumference. Landscapers formula is concentrated so use 1/2 ounce per inch of trunk girth. Find a liquid measuring cup with the ounce measurements on it. (Never use it for food again no matter how much you wash it.) I got a 32 ounce (quart size) at a local farm store and marked it for pesticides only. Pour the measured ounces into a large bucket and add 2 more gallons of water. Be sure to rake away debris or mulch within a 16" perimeter around the base of the tree trunk. Bare soil is best. Pour slowly no farther than 8" away from the trunk all the way around. If your tree is suffering, it will look bad during the summer and need till the next year before you see recovery. I understand 50% loss of tree leaf canopy is usually the limit though. Now, saying all that, I have been told to save your money and to not start treatment until the Emerald Ash Borer is within 15 miles of your trees. Not sure? Type in EAB infestation for your state and you should find a county by county map infestation graph. How long to treat? You will to do this once annually until the EAB on the infestation map disappears. It is worth saving these trees Martha. We are in it for the long haul.

Based on my experience, Tordon RTU Stump Killer will kill the stump of the plant it is applied to and plants within 2 to 3 inches of its stump/roots, but not harm plants that are further removed than that. Allan Lindrup, Chicago, IL

I live in a literal forest of poison oak. Had a few PO trees with 8" diameter trunks. Count your blessings. Anyway. The answer is... it depends on what you do and how careful you are. If the poison oak is growing up the tree, cut the poison oak stems and apply the Ortho un-diluted to the stump/s coming from the ground. If the oak is also all around the tree and ground based, spray very carefully, but with full coverage, and be sure not to have rain in the forecast for two days after. In two days you will notice the poison oak leaves begin to wilt. Do not cut out the poison oak until it is all wilted. If it isn't or you see any new growth, reapply very carefully again and you are done. Has worked, is working now for me, in the exact same situation. Been doing this same process for over 14 years. Including around my beloved firs and redwoods. Haven't hurt or lost one yet. Be sure to wear gloves. Don't do this when the wind is up. When you are done, take a full long warm shower. Just to make sure you get any poison oak or Ortho residue off you after cutting and tromping around in the Gawd-awful stuff. Our motto here: "All poison oak must die." Or while we are killing it: "Die oak die."

You can use it around trees. it's not enough to kill a tree. Be careful with shrubs. it will kill the leaves on them (turn them yellow). but if you trim those, the shrubs will sustain. I have used it around shrubs for weeds and just pruned the dying leaves out.

absolutely. It is useful for spraying on fruit trees while still in their dormant stage. You must cover the entire tree including the trunk to kill the eggs of insects and it will also help in reducing fungus to some extent. You should not use this spray once the buds have opened.

Use it full strength to kill stumps; mix it 1/2 cup to a gallon of water to kill brush. It will not kill broadleaf weeds or grass. I use it to kill aspen tree shoots in my yard and also have had good results killing fresh cut stumps.

I just sprayed the leaf area. My fear is that over spraying would kill everything in the area. Spraying the upper area seemed to be sufficient.

Hello Susan, I would not recommend this tool for that type of tree. That tree is more of a hedge than a typical tree with large limbs. There is also a correct way to prune this type of tree and you should follow that procedure in order to continue to enjoy the beauty and benefits of the tree. I included a website underneath for you. I hope this helps. http://extension.unh.edu/resources/files/Resource000594_Rep616.pdf regards frank

I have successfully used this on small stumps with two applications. Bore a large hole about 2 - 3 inches deep and 1 1/2 inches wide. Fill with Tordon and let stump absorb.Another sure fire is to use Muriatic acid (swimming pool acid) - drill and fill in opening. Bamboo is tough. You may need to experiment with combinations.

I used it to saturate the soil around the house, I would think it would work here as well.If the tree is or was infested, it may die.

I have a large honey locust tree in the area where I used the Tordon RTU and haven't experienced any damage to the tree, however it has been only a couple of months. I also didn't use very much, I had several weed tree's in the fence line that had gotten to about 2-3 inch diameter. I cut them as low to the ground as possible and painted the stumps with the Tordon, I didn't spray or pour it on the ground. So, I hesitate to say it's fine but so far so good with a very well established tree and limited use. By the way, it killed the weed tree's DEAD, lol!

Use wood lugs. Should be just fine. Make sure the lug is long enough to go about 3'' into the tree, through the bark.

The instructions say 4 oz. per gallon for various herbaceous plants (poison ivy, etc.), using a sprayer. You should set the sprayer on coarse spray, and wet foliage thoroughly, but not dripping. To zap stumps, use undiluted. It did a good job on Russian sage and unwanted Apache plume.
