Goran grass has taken over my flower beds where I have lily bulbs and day lillies planted. I want to dig up everything in the bed, treat the soil with a pre-emergent, and replant the bulbs. Bad idea?
Lynn F on Nov 25, 2017
BEST ANSWER: The barricade will not prevent the bulbs from coming up, so you can spray the entire flower bed with herbicide, say Glyphosate, then apply the pre-emergent, on top. Mulch and wait for the bulbs to return in the spring. Apply a second application of pre-emergent to the flower beds in the spring.

Does this control Japanese Stilt Grass?
A shopper on Nov 6, 2017
BEST ANSWER: Yes, Barricade would work to control germination of Stilt Grass. Preemergence herbicides - can be used on this summer annual but must be applied earlier than that targeting crabgrass. University research shows that PRE herbicides can be applied early in the spring or even in the winter and not lose significant length of control. This is because they are broken down microbially and cold temperatures in the spring limit microbial degradation from early applications. However, split applications are recommended in areas with prolonged germination of summer annuals.
Postemergence selective herbicides - can be used after stiltgrass has germinated but all POST herbicides are most effective on small, young weeds. Multiple applications are likely needed for best control.

Will product work on shiny leaf geranium?
LSR on Jun 24, 2017
BEST ANSWER: IT will work as a pre-emergent is you apply it at the correct time. The Shiny Leaf Geranium Once well established it is very difficult to eliminate. As a class B noxious weed it is a landowner�s responsibility to contain it however. As with most weeds it is important to take control measures before the plants go to seed.

Tk on Apr 20, 2017
BEST ANSWER: It all depends on how much you have applied per acre. Depending on the rate will depend on how long you will have to wait for germination to begin. The minimum time is 4 months. Depending on how big the spots are I would also recommend to give it some time and the grass will take over the bare spot in a few weeks sometimes it can take longer. Make sure to fertilize the lawn and water it frequently a healthy lawn will have less weeds.
