Kurt from Phoenix, Az writes
We're having a company cut down and grind our sissoo trees and apply an herbicide to the stump. But for any ancillary sprouts that pop up before the stump is fully dead, will this product work on killing those sprouts/roots? And does this leach through the soil to other plants in the area?
Yes! You need to use something like Fertilome Brush & Stump Killer or Crossbow and apply it undiluted to the freshly cut stumps/roots and then use it at either full strength or the highest dilution on any shoots that are coming up around the main stump. This will penetrate further into the root system to kill it out. You may have to cut back new shoots from time to time in the beginning as the Crossbow and Stump Killer products will only kill what has already emerged from the ground, not prevent the new seedlings still below the surface from sprouting up. Over time the stump and root system should die out and eventually break down in the soil. As long as the Fertilome Brush Killer and Stump Killer is only applied to the trees you need to kill, it will not effect surrounding trees.
Thank you,
