To effectively kill crepe myrtle roots, there are a few methods you can consider. One option is to use a phenoxy herbicide product like Dicamba or 2,4-D. These herbicides are systemic, meaning they are absorbed by the plant and distributed throughout its system, including the roots. When applied correctly, they can effectively kill the crepe myrtle roots and prevent regrowth.
When using a herbicide, it is important to follow the manufacturer’s instructions carefully. This includes wearing protective clothing, such as gloves and goggles, and applying the herbicide at the recommended concentration and rate. It is also crucial to apply the herbicide only to the crepe myrtle roots and avoid contact with desirable plants nearby.
Another option to consider is using a plant growth regulator called sucker stopper. This product works by inhibiting the growth of new shoots and suckers from the crepe myrtle roots. By suppressing the growth of new shoots, it can help control the spread of the plant and prevent it from regrowing from the roots. Sucker stopper is typically applied as a spray to the base of the crepe myrtle, targeting the area where the roots emerge from the ground.
In addition to using herbicides or growth regulators, physical removal of the crepe myrtle roots can also be an effective method. This involves digging up the roots using a shovel or other digging tool. It is important to dig deep enough to remove as much of the root system as possible to prevent regrowth. However, this method can be labor-intensive and may not be practical for large or established crepe myrtle trees.
It is worth noting that killing crepe myrtle roots may not always be necessary or desirable. In some cases, it may be more practical to manage the growth and spread of the plant through regular pruning and maintenance. This can help keep the crepe myrtle in check without the need for drastic measures to kill the roots.
The choice of method to kill crepe myrtle roots will depend on factors such as the size of the plant, the extent of the root system, and the desired outcome. It is recommended to consult with a gardening or landscaping professional for personalized advice and guidance based on your specific situation.
