How did dodder get in my flower garden?

Question:

I’ve discovered dodder in the coreopsis in my flower garden. I am trying to stay ahead of a takeover by daily removal and sequester of cuttings. How did it get in my garden?

Dodder is spread by a relatively heavy seed so it generally comes in on soil or equipment moved from an area that had dodder.  Here is a good resource about this tenacious “plant” https://hort.extension.wisc.edu/articles/dodder-cuscuta-spp/
