response: Hi,  The picture you've sent is a grassy weed called Annual Bluegrass, or Poa Annua. It's an annual grass that you can control in your garden bed simply by pulling it out. There may be some other weeds there as well, it's hard to tell in the picture, but I would start by simply pulling them by hand, planting your garden, and using a mulch to control further weed growth.  Here's some additional information about Poa Annua and about using mulches.  https://www.canr.msu.edu/ipm/diseases/annual-bluegrass https://www.canr.msu.edu/news/smart_gardeners_improve_their_soil_and_weed_control_with_organic_mulch There are not really any herbicide treatments that work well for controlling Poa Annua in the lawn, since any herbicides that will kill it, will also kill your lawn. Instead you can consider raising your mowing height, which will help the grasses you do want grow stronger. You can also reduce irrigation if it's being used, this will make it harder for the Poa Annua to compete with your desired grass species. Here's some additional information on the effects of raising your mow height and about watering your lawn. https://www.canr.msu.edu/resources/mow_high_for_weed_and_grub_control https://www.canr.msu.edu/resources/smart_watering_for_lawns_dont_let_the_lawn_squeeze_you_dry An additional resource if you're interested in learning more about safely using herbicides. https://www.canr.msu.edu/news/avoid-herbicide-misuse-at-home-things-to-know-before-you-buy If you do decide to use any of the products you mentioned, you must read and follow the directions on the label.  Thanks for reaching out with your question!

response: Thank you for following up.  In that case, I’ll simply pull all the Poa Annua from our garden bed before we plant vegetables.  I’ll also use Round-Up on the 3-4 small spots of our lawn where the Poa Annua is present and then replace those spots with new sod.   Best regards, Matt Hiser Cell:<personal data hidden>     From: ask=<personal data hidden> <ask=<personal data hidden>> On Behalf Of Ask Extension Sent: Tuesday, May 16, 2023 4:28 PM To: Matthew F.
