Morning Glory taking over garden, What to replace Morning Glory with?

[summerbreeze8]

Morning Glory was already growing here and there in the area below the spring where we've put our vegetable/fruit garden. The area was once used as a field early last century here in Eastern Oregon. The garden is two years old.

This year MG is taking over the garden. I have 4 plots -- one for compost, two for compost crops (barley now/Austrian peas this winter), and one for garden.

I covered the garden plot with thick newpapers. The MG is sneaking out through the overlapped papers.

The MG is even growing in my compost pile! Next pile I'll start the pile with cardboard.

I get that the site needs a plant that puts down DEEP roots that creep along horizontally. Does anyone have an idea of what I can plant that does the same thing? I'd like to plant something as a cover crop to compete with the MG.

Warm welcome summerbreeze8!

Morning glory is rampant here (in Cambodia)...maybe different variety but it's a big food crop, typically stir-fried in oyster sauce...you didn't mention if you're eating it or not?
are you looking for another rampant edible to compete with the MG? and/or do you want to get rid of the MG completely?

Peace
