Raised beds where horsetail is growing?
I have a portion of my yard that I want to use for a vegetable garden, using raised beds. (I haven't put in the raised beds yet.) Currently, the area has horsetail growing over about a 15' x 10' area. What can I do to keep the horsetail from overrunning the vegetable garden?

Equisetum (Horsetail) is never easy to offer advice about. It is tough! I tell myself to admire it while pulling it regularly in an attempt to control the spread. The goal is to find a barrier to block the plant growing into your raised beds, while allowing water to move out of the soil. Here is a publication about the plant and offering some control options. I have not found University Extension Service advice published about how to keep it from raised beds. http://hortsense.cahnrs.wsu.edu/Search/MainMenuWithFactSheet.aspx?CategoryId=6&ProblemId=2024 I will refer your question to other experts and if someone has research-based information and advice, you will get another response.
