    Q
    Will Crossbow leak into the groundwater after heavily applied to the fresh cut stumps of the "Tree to heaven"
    Like well drinking water
    A

    Crossbow Herbicide does contain an active ingredient that has soil residual. Per the product label:  "This chemical has properties and characteristics associated with chemicals detected in groundwater. The use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination."

    If you are applying the product as directed to apply to fresh cut stumps, then there should not be a risk of contamination in most circumstances. However, this product is not labeled for use around aquatic areas or where there is risk of flooding.

    Q
    How much space is need to not harm established trees while using Crossbow Herbicide?
    I have established trees in a rock area that gets over run by morning glory. Will Crossbow kill the morning glory and can I spray the rock but not saturate it? I do not want to harm the trees or blueberries. How far away do I need to stay? I am looking to spot spray mostly.
    A

    As long as you are not spraying Crossbow Herbicide directly on the desirable tree leaves/roots or blueberries it should not harm them.  That being said, it is not labeled to be used around edibles, so applications should be kept outside of the dripline of the blueberry plants.

    Q
    Is Helena Crossbow Herbicide useful for killing bamboo?
    A

    Crossbow Herbicide is not labeled  for bamboo, however we have heard if you cut down the bamboo level with the ground and apply Crossbow or a similar Triclopyr based product undiluted to the fresh cut it can help kill it out. Bamboo is extremely stubborn, so it can take several steps to remove it completely. You can use Round Up QuickPro at the highest listed usage rate to help eliminate bamboo. You will be required to cut the bamboo down to a short stump and then apply the Round Up QuickPro. It can take several applications to achieve the desired results.

    Crossbow was sprayed at or near the dripline of several of my rose bushes and they now have damaged leaves and young growth, although the bushes are still alive.
