Max from Keosauqua, Iowa writes

What would be the best herbicide to kill both grass and blackberry in and around black walnut and oak?

Is there an all in one or something that can be added to a product such as Roundup.


Unfortunately, herbicides that will kill the blackberry would also damage the black walnut and oak trees. Roundup QuickPro is the best option to treat around desirable trees, ornamanets, and shrubs since it does not leach in the soil.
