I have dymondia in my yard. there is a major infestation of clover and a couple of other weeds that I have been trying to control manually--but I am losing out and wondered if Round Up or some other weed killer would treat this condition without harming the dymondia? Peter
We don't give product recommendations - it would be best to visit a local garden center for advice about herbicides. But I can tell you the Roundup is a nonselective herbicide which means it kills everything. You can check some labels on selective herbicides and see if dymondia is listed as a plant that will or won't be killed.
Here are two articles that should help:

I would not fertilize Dymondia. They are native to low fertility, high draining soils. These articles will help:

We do not recommend places for purchase of plants. I could recommend checking with your local nurseries, or online.
Why does my dymondia sometimes die in spots, only to eventually grow back. How can I stop this?
Unfortunately, your photos did not come through. I am unable to identify the issue. It sounds like it could be a fungal or bacterial infection, though. Fungicides may help.
