I want to mulch around my bushes/flower beds.?

If I lay down plastic first, will this stop weeds from coming up ? Should I pull most of the weeds out first or use spray weed killer ?

Don't use plastic they make something called landscape fabric. It lets the rain and your watering get through ,plastic won't. Pull most of the weeds first getting the root if possible. Using a weed killer will hurt the plants that you plant there.
Reply:The best thing to do is pull the weeds out first give a good fertelize then place down the plastic or get something called a landscape matting which will allow water to get to the ground but will stop weeds, then place mulch around nice and thick which this will also help keep the plants cool around the roots.
Reply:Pull the weeds first. weed killer might harm the bushes and flowers. Plastic works great but eventually, it will get tears and cuts in it but the mulch will also help with weed control.
Reply:I never use plastic or landscape fabric, because eventually the weeds push through. Use a weed killer 1st, then lay down the mulch.
