Kirk from Prairie Du Chien writes

Can I use Grass Out Max on a woodland tree planting to kill the grass around trees like oak, walnut, and maple?

When is the best time? At green-up?

Answer:

Yes, you can use Grass Out Max to control invasive grasses around your Walnut, maple, and Oak trees.  The best time to apply is when the grass is young and actively growing.
