Establishing a row garden #929215

Hi. We've been gardening in our Fort Collins back yard for many years using raised beds. However, in an attempt to make irrigation a little simpler, I'd like to try gardening directly in the ground using two long rows. The challenge is that our yard is loaded with bindweed which has infiltrated the garden. My question is -- is there a way to first eradicate the weeds and then establish a design that might help resist weed infiltration? One thought I had was to first put plastic over the entire garden (for 5-6 weeks?) to kill off the bindweed. Next, dig the garden row trenches (e.g., one foot wide and one foot deep) and then fill in the trenches with garden soil. I would then cover the ground adjacent to the trenches with mulch. I figured this should keep the bindweed out for a few years, but then I might have to repeat the process. What do you think? Other than using plastic to initially kill off the bindweed, I'd rather not use any more plastic or weed barrier within the garden. Thanks for any insights!

Hello,
Yes, you can solarize, but you need to do this during the hottest time of the year (July-August). Doing it now wouldn't provide enough heat to kill off the weeds and most of the roots.
Should you do this route, use 4 mil clear plastic. Water in the area really well so it's very moist. Put the plastic on top of the space and seal in the edges with soil. You want to make sure the plastic is very secure, because the wind will be an issue.
The other option would be to use a non-selective herbicide and spray the bindweed at least twice (three times is better). Products like glyphosate or horticulture vinegar can work, but read the label and apply as directed. Wear the proper PPE when spraying. Reapply after 10-14 days.
