Q.horsetails and clover
I have some beds that have a thick layer of horsetails, which for the most part I like, as they provide a nice ground cover. They can creep into the lawn but weed killer seems to control them. However, last year I started getting a lot of clover mixing in with the horsetails in my beds, and it’s not a good look. I’m wondering if there is a way to control the clover or a chemical that will get rid of it without harming the horsetails. I need to do something, as my beds are beginning to look bad. Thank you very much.

Most herbicides that will kill clover will also kill horsetail, so I'm not sure if chemical methods will work. However, glyphosate is said to only temporarily harm horsetail:

Otherwise, hand weeding may be your only option.
