Planted Dymondia Margaretae about 3 yrs ago and last year started seeing lots of burr clover & oxalis weed invading in my established dymondia. The dymondia is so tight that I can manually pull out the weeds by their roots & now there are too many. Can Hi Yield 2, 4-D kill weeds but leave Dymondia alone? If not, can you recommend a product that will, please
Hi - Yield 2, 4 - D Selective Weed Killer is not safe to use on groundcovers such as the dymondia. Unfortunately, we do not have a selective herbicide that would kill weeds such as clover and oxalis without also injuring the dymondia. You would need to hand pull or spot treat carefully using a non-selective herbicide such as Hi-Yield Killzall Quik RTU. You can use a pre-emergent such as Pendulum 2G to help prevent new oxalis and other labeled weeds from germinating with fall and/or spring applications.
