When spot treating with Tenacity Herbicide, you can aerate any time after that without any issues. If the plan is to make a broadcast application, we recommend to aerate before the treatment is applied.
The product label states that Tenacity acts as a pre and post emergent on bentgrass so it should help prevent it for at least a few months if applied at the right time. As a post emergent, you would apply it as you start to see new signs of bentgrass growth at two to three week intervals for up to three applications. Twice a year would not be enough for a post emergent control but can help to prevent it. Bentgrass control may be more effective in the late summer/early fall just prior to onset of renewed bentgrass growth, rather than spring/early summer applications.
No, you should not use Tenacity Herbicide on or around desirable ornamental plants or groundcovers, such as liriope. Please let us know what weeds you are targeting so that we can recommend an alternative product for you.
Tenacity Herbicide should be used just before the soil temperatures reach 55 degrees in early and late fall. Please contact your local cooperative extension office to determine the correct timing of the application as this will vary greatly from region to region.
